悬浮剂的内控指标与检测方法

外观、有效含量、悬浮率、密度、细度、分散性和稀释稳定性、离心稳定性、pH值、冷热贮稳定性、粘度以及水质、水温适应性等，具体要求如下：

1. 外观

包括颜色、物态、气味等。颜色一般为乳白色最佳，物态一般为粘稠的可流动性的悬浮液体。

2. 有效含量测定

有效成分为5%~80%，多数为40%~60%。根据有效成分的性质确定相应的分析方法，然后进行制剂的含量分析，一般采用液相色谱分析。

3. 悬浮率测定

称取1g左右的悬浮液于250 mL量筒中，用342 ppm的标准硬水稀释，然后上下振荡30次，30℃恒温水浴中静置1个小时后，取走上层225 mL的悬浮液，用蒸馏水将余下悬浮液转移至小烧杯中，烘干（80℃）后用甲醇溶解并定容至10mL容量瓶中，用液相色谱分析。

4. 密度测定

取10mL容量瓶一只，称取待测悬浮剂质量a (精确至0.1mg)，再用吸管吸取水悬浮剂于10mL容量瓶中并定容至10mL，称取两者质量b，以（b-a）/10即得水悬浮剂密度（g/mL）。重复三次，取算术平均值。

5. 细度测定

水悬浮剂径粒一般控制在1~5µm。径粒的测定方法多种多样，归纳起来分为两种：一种是目测法，借助显微镜观察统计，计算出该悬浮剂径粒的算术平均值，具有相对的准确性；另一种精确的方法是采用先进的仪器测定，如采用光透射式粒度分布测定仪、微机处理粒子谱和激光衍射粒度分布测定仪等进行测定。

6. 自动分散性及稀释稳定性测定

于100mL具塞锥形量筒中，装入99.5mL标准硬水，用注射器取0.5mL待测水悬浮剂样品，从距量筒水面5cm处滴入水中，观察其分散状况。按其善的好坏分为优、良、劣三级。

优级：在水中呈云雾状自动分散无可见颗粒下沉。

良级：在水中能自动分散，有颗粒下沉，下沉颗粒可慢慢分散成轻微摇动后分散。

劣级：在水中不能自动分散，呈颗粒状成絮状下沉，经强烈摇动后才能分散。

稀释液30倒置次后置于30±1℃的水中，静止1h。若上无漂浮物下成沉淀则为合格。

7. 离心稳定性测定

取3支带刻度的5mL锥形玻璃管，每支准确加入5mL待测悬浮剂，然后对称放入离心机中，以3000r/min离心30min后取出，观察记录析水和沉淀情况。按析水和沉淀体积多少分为优、良、劣三级。

按析水情况分级：

优级：析水体积＜1%或无析水

良级：析水体积＜5%

劣级：析水体积＞5%

按溶液体积多少分级：

优级：沉淀体积＜1%或无沉淀

良级：沉淀体积＜5%

劣级：沉淀体积＞5%

8. pH值测定

PH值一般控制在7~9。测定方法：于100mL烧杯中，称取0.50g待测悬浮剂，用蒸馏水稀释至50.00g，混合均匀后用PH计测定。

9. 热贮稳定性测定

将待测水悬浮剂样品用安培瓶密封后放于54±2℃的烘箱中，静止热贮14天后取出，分别检测记录外观、流动性、分散性、径粒、有效含量、悬浮率等各项指标有无变化。若贮前与贮后相同或有轻微变化（其变化应在允许范围内），视热贮合格。其中，物理稳定性方面，若有油或沉淀析出为不合格，析水率以小于5%为合格。其结果相当于常温下贮藏两年，产品合格。

10. 冷贮稳定性测定

将待测水悬浮剂样品用安培瓶密封后放于0℃、-10℃和-20℃下贮存一定的时间，取出后观察结冻情况。然后在室温条件下静置融化，并分别检测记录外观、流动性、分散性、径粒、有效含量、悬浮率等各项指标有无变化。若贮前与贮后相同或有轻微变化（其变化应在允许范围内），视冷贮合格。其结果相当于常温下贮藏两年，产品合格。

11. 水质适应性试验

取100mL具塞锥形量筒三个，分别装入0ppm、342ppm、500ppm硬水99.5mL。用注射器分别取0.5mL待测悬浮剂依次从量筒水面上5cm处滴入水中，观察分散性和悬浮稳定性。若能自动分散，振荡后静置1h后，上无漂浮、下无沉淀即为合格，表明该悬浮剂对水质的适应能力强；反之，则适应能力差，悬浮剂不合格。

12．水温适应性试验

取100mL具塞锥形量筒三个，分别装入15℃、25℃、35℃ 342ppm标准硬水99.5mL。用注射器分别取0.5mL待测悬浮剂依次从量筒水面上5cm处滴入水中，观察分散情况。若能自动分散，振荡后静置1h后，上无漂浮、下无沉淀即为合格，表明该悬浮剂对水温的适应能力强；反之，则适应能力差，悬浮剂不合格。

13. 粘度测定

粘度是影响农药悬浮剂稳定性的主要因素之一，因而是农药悬浮剂的主要技术指标。

测量粘度的仪器有多种，常用的有N式粘度计、旋转式粘度计，根据农药悬浮剂的性质，一般选用旋转式粘度计测定简洁方便。

欧盟生物杀灭剂有效成分评审计划

2012-07-03T20:04:00.000-07:00

上海老顾杀菌博客：http://www.shajunji.blog.sohu.com/

欧盟生物杀灭剂有效成分评审计划

根据BPD法规要求，需要在欧盟层面通过技术评审建立一个准许用作生物杀灭剂产品的有效成分清单，也就是BPD法规的附件I或IA。只有被列入到附件I或是IA 的物质才能被用作生物杀灭剂产品投放到市场；与此同时，对2000.5.14日之前在欧盟市场上已存在的生物杀灭剂用途的物质，可以通过BPD缓冲期条款获取被列入或不被列入附件I或IA评审决议前的临时授权在市场上流通。这里涉及到的附件I和IA，就是欧盟BPD法规下进行的有效成分评审10年工作计划（以下简称：“评审计划”）的目的。

评审计划分三个阶段进行：

第一阶段，市场上的物质信息排查：2000年7月9日，EC. 1896/2000号指令，要求业界对用于生物杀灭剂产品用途的有效成分进行认定并提供产品相关信息的通报（截止通报日期2002年3月28日）。

第二阶段：提交正式卷宗：2003年11月4日，EC. 2032/2003号指令。此阶段主要工作包括：1）在第一阶段的基础上构建已有有效成分清单(Existing Active Substance List)；2）已通报待评审物质清单；3）评审计划时间表，包括评审的优先级，卷宗的提交截止时间等；4）不被准许用于生物杀灭剂用途化学物质清单；5）前2种优先评审类物质评审发起国清单；6）卷宗提交，评审及沟通程序。

第三阶段：卷宗评审：2007年12月4日，EC. 1451/2007号指令出台。在前两阶段的基础上，第三阶段的主要工作是对已收到的注册卷宗评审。主要规定了评审的具体步骤和办法，并在其附件-II中列出了所有通报物质评审相关的物质CAS及EC编号，评审发起国、产品用途等信息。

通过第一阶段，欧盟完成了964个在2000年5月14日在市场上用作生物杀灭剂用途的有效成分认定，其中416个物质完成了一个及几个用途下的通报评审，此外的548个（约60%）已在2006年9月1日前退出作为生物杀灭剂用途的市场。截止2008年3月1日，约一半的通报物质（包括物质下的产品用途）没有提交完整卷宗授权申请。根据最初评审计划，每个物质评审需要2年时间，完成所有卷宗评估工作应该会在2010年结束。但由于评审工作的复杂性，当局机构缺乏足够的技术工作人员，缺乏相关物质的评审经验，需要开发各种用途下的测试方法和暴露场景等原因，导致实际每个物质的评审时间至少需要3年，平均需要4-5年。随着卷宗评估工作的逐步开展，目前只有少部分物质完成评审被列入到Annex-I（54个）或 IA（2个）[截止到2012年5月12日]，尚有300多个有效成分在评审中，最新的评审计划完成时间已被推迟到2014年。此外，根据新法规的变动，ECHA将于明年逐步接管评审工作。

BPD法规的实施及评审工作的开展对欧盟杀灭剂市场将造成如下影响：

1）被准许使用的有效成分大大减少。据统计，自BPD生效到2010年，欧盟市场上1000多种约2/3的有效成分由于各种原因被淘汰，并随着评审的进行，还将有很多在评审中的物质或是用途不被列入到附件中。预计到2014年欧盟市场上准许使用的有效成分可能会少于300个。

2）市场存在一定程度的垄断，产品价格将会提高。由于应对BPD法规的成本花费很高，只有一些少数化工巨头有实力和意愿去应对，并且授权物质将有10年以上的数据保护期，很多中小企业不得不退出市场或被一些大的企业所并购，形成市场垄断，同时推高市场上相关产品价格。

3）新产品上市速度下降。由于生物杀灭剂类产品的很多细分市场并不是很大，与相应的产品研发及法规应对成本不对称，导致很多业内企业采用防御性市场策略，缺乏开发新产品的源动力。

4）某些有害生物对产品的抗性会加剧，主要原因是可选的有效成分减少，缺乏足够的替代产品。

Dinotefuran research and development concern

2011-08-05T01:01:00.001-07:00

Given Dinotefuran good market prospects and applications for domestic and foreign varieties of pesticides features faster updates, relevant domestic agencies should increase Dinotefuran research and development efforts, increase the new neonicotinoid insecticide create work .

       Dinotefuran East Chemical Co., Ltd. is Japan's Mitsui development, and in 2002 listed the new neonicotinoid insecticide. It is the only non-chlorine pesticides, alkali atoms and aromatic rings, called third-generation neonicotinoid insecticide, has a super-efficient, broad-spectrum, with less toxicity is low (slightly toxic preparation level), lasting effect, without injury to crops, the use and safety. With the Chinese market in the near future, the patent is about to expire, Dinotefuran with good prospects for the development and application, should attach great importance to the industry.

        Special structure and excellent performance. Dinotefuran other neonicotinoid insecticides with different structures, characteristic of the (±) tetrahydro -3-- methyl furan structure, rather than all the other neonicotinoid-based material has the pyridine structure. As the special structure, performance, compared with more traditional neonicotinoid insecticides excellent, not only in rice, vegetables, fruit trees, flowers on the Hemiptera, Lepidoptera, Diptera, Hymenoptera beetles and the total head pests efficient, and effective on the pests have become a very promising development, structural novelty, there may be a large world-wide variety of pesticides.

        Demand prospects. Neonicotinoid insecticides on the market to become mainstream in recent years, domestic and foreign varieties of pesticides and good momentum of development, imidacloprid, acetamiprid, nitenpyram, imidaclothiz, thiacloprid, have already produced domestically; pesticides "four kings" is one of fogo new neonicotinoid insecticide thiamethoxam and new varieties of insects benzamide compound of chlorine products, as domestic rice fields one of the largest amount of pesticides. It is predicted that by 2012, global neonicotinoid insecticide sales will reach $ 2.5 billion, jumped to the entire class of pesticides will be the first of pesticides. Neonicotinoid insecticides not only environmentally friendly, low toxicity, and is consistent with the national conditions of China's crop, a new neonicotinoid insecticide can control the various varieties of rice insect pests. Rice is the first major crop, planted area of 43,000 acres, domestic rice prices soared in recent years, rice yield and quality by the state's attention, no doubt greatly promote a new neonicotinoid insecticide market demand; the same time, a ammonium phosphate, five kinds of highly toxic pesticides delisting, the disabled Fipronil insecticide to the domestic market leaving a huge supply gap. In recent years, foreign multinational giants vied for pesticide paddy field pesticide market is indicative of the potential of the domestic market attractive. As countries continue to increase environmentally unfriendly pesticides remediation efforts, the development will bring new neonicotinoid pesticides historic opportunity.

        Resistance factor is low. With the neonicotinoid pesticides widely promoted, many pest species on the main neonicotinoid pesticide imidacloprid has generated a certain amount of resistance, the data reported shows that in a region already acetamiprid and Nitenpyram also had a resistance. Furosemide is not yet listed as the first generation of pyridine amine neonicotinoid insecticide alternative varieties, the future does not exist within a short time a similar problem.

        Patents about to expire. Dinotefuran since 2002 in Japan, in 2005 in the United States, then in Europe, 2012 listed in mainland China, the patent expired in 2014, currently doing the preparatory work should begin.

Research has been based. Currently part of the research structure has been carried out Dinotefuran and synthesis intermediates, synthetic route as reported in the literature many domestic research focused on the malonate and ethyl bromoacetate as the starting material for synthesis of 3 - tetrahydrofuranmethanol and further prepared by reacting an important intermediate 3 - tetrahydrofuran methylamine, then the other intermediate O-methyl-N-nitro-N '- phthalimido different urea synthesis furosemide pyridine amine. Currently has three companies Jiangsu, Zhejiang industrial production Dinotefuran key intermediate 3 - tetrahydrofuran methylamine, and export reports, the quality of products fully meet the foreign production Dinotefuran requirements.

        Given Dinotefuran good market prospects and applications for domestic and foreign varieties of pesticides features faster updates, relevant domestic agencies should increase Dinotefuran research and development efforts, and Dinotefuran and with other common pesticides agents such as pyrethroids, organophosphate, carbamate complex with the study of imitation at the same time, should learn from foreign advanced experience, increase new neonicotinoid insecticide create work.

SC pesticide problems in the production process summary

2011-08-03T22:13:00.001-07:00

Oh, this is some of my friends asked, I made some simple answer, because the specific equipment and processes depends on the difference, then make some adjustments to the corresponding. Oh, there may be problems this group of colleagues is no stranger to it, because the same set of questions may also be asked several of our senior technical staff, alas! Perhaps few of us the answer is the standard of the cross.

1, SC large-scale production, the temperature at 30 degrees below room temperature at 30 degrees or more, do get it? What are the requirements of the condensate?

A: The temperature at 30 degrees below, you can control that, if use of groundwater, or condensing heat exchanger using water temperature can also drop off.

2, SC in large-scale production, particle size testing instruments need to complete it? Also need to measure what the instrument or test which indicators?

A: Yes, with a particle size analyzer, without conditions, if the fixed species and processes, grinding the slurry to send in the vicinity of the detection unit for inspection, sorting out the number and size of the abrasive relationship between the future is business as usual. Particle detector is basically the main instrument.

3, SC, when large-scale production, the added amount of defoamer is how to control and determined? To what extent to remove the bubble can only be packing?

A: The beginning part of the deployment are added to the slurry, the slurry after grinding later observed bubbles situation. If increased significantly and difficult to eliminate, as part of continuing additional defoamer. Basically, in order to eliminate the bubble does not affect the extent of the standard cans, for example: 200ML bottles fitted 200G, found in or near the bottleneck of the overflow is still needed on the defoaming products.

4, large-scale production SC, sanding there creaming What causes this? How to solve it?

A: The direct and formulation screening of a great relationship, not the best optimized formulation screening point. But in the process of large-scale production problems exposed.

5, SC packaging materials are no restrictions or how to choose?

A: SC package no special restrictions on the basic material, commonly used bottle is possible.

6, SC large-scale production, if the original drug into particles or a large block, need to pre-crushed (jet mill) it?

Homogeneous machine or directly into homogeneous?

A: The discovery of the original drug in large particles and block the original drug, it is best not to directly feed, easy to damage your machine or homogeneous locking motor burn. Generally require pre-crushing machinery like, not necessarily the air, you can crush the ordinary.

7, SC return if there is how to solve quality problems? (Agglomeration, stratification)

A: unpacking, ready to rework. Packaging materials, transportation, labor, wear and tear is inevitable. Analysis of hierarchical agglomeration of the reasons that have been layered slurry for processing. If the large particles, you need to re-sanding, Pour the clear liquid, the lower recovery of the active ingredient, the final concentration in the sample test, re-determine the content of preparation. If the slurry to flow, little change in size, to analyze whether or corruption caused by the lack of thickeners, fungicides may be additional thickener solution.

8, suspended emulsion (SE) processes which are now the most popular? (By hanging tricyclazole propiconazole emulsion, for example)

9, laboratories SC configuration, the material than how much? (We generally use 1:1-1:2)

10, large-scale production SC, three sanding is how to do is two or three series it is a cycle?

A: We are using imported sand mill, grinding efficiency is much higher than domestic. General domestic line is at least two series sanding, if the conditions that three series, set different grinding accuracy and efficiency.

11, large-scale production SC, the weather temperature (temperature above 35 degrees or below 10 degrees cold) What is the impact of processing?

A: The temperature is generally not much of an impact, only a positive effect.High temperature, then easily lead to evaporation of water, bubbles increased, the slurry temperature is too high, causing the cream of the phenomena.

12, SC formula, why not use PVA as a thickening agent (I think the pva color is good, but also to prevent coagulation)? PVA solution process is complicated reason?

A: The trouble is not dissolved, because as a thickener xanthan gum thickening effect a good, easy to use. So rarely use PVA, unless made in a number of FS in the film former (and be vigilant, because the harm likely to lead to closed types).

13, SC formulations, with a strong dielectric (high concentration) as the dispersion medium (the application has affected the additives), how to choose the right agent? (Glyphosate salt solution to make media)

A: There is no good way, only you do more screening formula, whether or thickening agent system, system of high-electrolyte systems are not ideal.

14, I have tested the seed coat of different companies at home and abroad suspension products, domestic general place six months to a size 70-100um, foreign countries can also control the 5UM below. It can be seen, the domestic chaos and the quality varies greatly additives, the additives in China to develop? Haha.

Some of the things on paraquat

2011-08-03T01:23:00.001-07:00

Some time ago that a news is the inclusion of paraquat PIC export restrictions on a list of news, which led to panic. We take a look at the reasons included in the PIC:
1 paraquat itself dangerous, the most likely cause of illness and death; 2 did not fully fulfill the obligations of the risk; 3 did not fully warn coverage can lead to illness and death. Read these reasons, we can not help but feel a little far-fetched, as the pesticide paraquat toxicity is definitely yes, if the man's suicide led to paraquat to back this offense, I think other varieties of the same pesticide is to be prohibited. Or to see our experts say and recommend it.
Shandong Pesticide Research Institute, Li Dejun that, objectively, in the production and distribution of paraquat and the normal application process, harm human health and the environment is extremely meager, man-made suicide are intentional misuse, but are not recognized by conventional orpractices lead to accidents. PIC Convention, of course not included in the list as the reason.
    This Lide Jun proposals, one management immediately stop pesticide paraquat new registration, the existing product label paraquat on uniform regulations and standards manual and promotional materials, all the labels, logos, brochures and other promotional materials must be significantly location paraquat risks to human health to illustrate the text with eye-catching, eye-catching label must be a unified set of poisoning helpline phone number, note the use of paraquat, paraquat on the characteristics of human health hazards and emergency rescue method. Do not follow regulations and standards and other promotional materials printed label products, to cancel the registration.
    Second, the national product standards and national standards committee report recommendations, modify standard products, uniform packaging specifications shape, from product performance (such as solid dosage forms, viscosity, etc.) and increase consumer packaged form or wrongly taken poisoning impulse difficult. Effective relief of human health hazards.
    Third, the proposed China Pesticide Industry Association, the organization up and paraquat, paraquat to establish a safety management of the Fund, its purpose is: to establish a standard to prevent pesticide poisoning and first aid platform to enhance the training of primary health care system, medication safety for farmers and characteristics of paraquat poisoning and emergency first-aid training, relevant international organizations and experts to appeal to our reason and scientific basis. Paraquat printed promotional materials or CD-ROM with the knowledge, widely posted and disseminated.
    Fourth, to promote the central and local pesticide management and law enforcement agencies to increase enforcement of the paraquat national standard. Organization of paraquat product quality checks, the proposed two random failure of the manufacturers, should revoke the registration of their products.
Do not know these bits, the fate of paraquat did not help. After all, as the world's second largest selling varieties of pesticides paraquat and China as the world's largest supplier of injury is difficult to afford ah.

Failure to identify four methods of pesticides

2011-08-02T01:23:00.001-07:00

Intuitive method for powder pesticide, pharmaceutical exterior look, if you have that wet agglomeration, Smell no smell and thick, or other groups can be twisted by hand, indicating that it has basically failed; of pesticide emulsions, first bottle standing, If the liquid turbid or stratification that oil-water separator, a generation or floc sediment suspension, indicating that agents may have failed.

Heating method for powder pesticide. Take 5 to 10 grams of pesticides, on the sheet metal on the heat, if they have a lot of white smoke, and have strong pungent odor, indicating a good agent. Otherwise, the note had expired.

WP floating method for pesticides. 200 grams of water glass first, then weigh 1 gram of pesticides, gently and evenly spread on the water look closely, within 1 minute and can sink into the wet water is not expired pesticides, or is the failure of pesticides.

Hot-melt emulsion method for pesticides. To have even the bottle of pesticide sediment into the warm water in the wet with not too high, to 50 ℃ ~ 60 ℃ is appropriate, for 1 hour after the observation, if the precipitate slowly dissolved, indicating agents has not yet expired, until the precipitate dissolvedcan continue after the re-use; if precipitate insoluble or insoluble, indicating that has failed and can no longer work.

"Fwelve Five" Pesticide Industry Development Plan (Full Text)

2011-08-01T22:55:00.001-07:00

Pesticides is an important agricultural production and relief supplies, the prevention of agricultural pests, to protect agricultural production and rural incomes and agricultural storage plays an indispensable role. At present, China 90% of the pesticides used in agricultural production, non-agricultural use of pesticides accounted for about 10%.
First, the Status and Problems of Development
(A) Status
        After years of development, China has formed, including research and development, the original drug production, formulation processing, raw materials and intermediates, pesticides, supporting more complete industrial system, pesticide production capacity and production has been in the forefront of the world, steadily improve product quality, variety increasing the quality and efficiency of agriculture provides a strong support.
         Industries have been expanding. As of 2010, more than 1,800 pesticide manufacturers in China, where more than 500 original drug manufacturers, the industry employed 16 million people. By 2010 sales value of 158.96 billion yuan at current prices, profit 8.69 billion yuan, total assets of 124.69 billion yuan.2010, China produced 2.342 million tons of pesticides (active ingredient fold), an increase of 20.4%, export 613,000 tons, an increase of 20.8%. In 2010, China's pesticide production capacity of over 2 million tons, preparation of production capacity of more than 500 million tons, sales of more than 1 billion business over eight pesticides, the main business for the 18 pesticides listed companies. Shown in Table 1.
Product mix continued to improve. At present, China can produce more than 260 perennial species of the original drugs, more than 3,000 varieties of preparations, highly toxic pesticide reduction plan implemented smoothly and in 2007, methamidophos, monocrotophos, five kinds of highly toxic organophosphate to stop production and all varieties used by a number of high efficiency, low toxicity pesticide products to optimize production processes, efficient residue varieties accounted for 95%. Three varieties from the structure, the declining proportion of pesticides in 2005 from 41.8% down to 31.4% in 2010, the proportion of fungicides and herbicides from 2005 to 10.1% and 28.6%, adjusted to 2010 was 7.1% and 45.0%, the structure of varieties have been greatly improved. Table 2.
Research and development capabilities have been enhanced. "Eleventh Five-Year", China's increased investment in research and development, the establishment of a north-south Pesticide Center, relying on the existing strength of pesticide research, create a group with independent intellectual property rights and efficient pesticide varieties, such as insect pesticide sulfur nitratephosphorus, the grass herbicide-propyl ether, morpholine fungicides such as fluorine.
(B) problems
          China's rapid industrial development of the pesticide, long-term accumulation of contradictions and problems have gradually emerged.
          1 industry concentration is low, small scale enterprises. China's current pesticide production enterprises more than 500, scattered layout, smaller, has not yet internationally competitive enterprises. The following sales of 50 million yuan more than 250 companies, top 10 pesticide companies the proportion of sales accounted for only 21.9% of the industry.
           (2) capacity for independent innovation is weak, the low level of technology and equipment. The vast majority of agricultural pesticide R & D investment accounted for sales of less than 1%, only a few companies in the production of individual products to achieve a continuous, automated, most companies still focus on using process parameters shown in situ or manual remote control, capacity The increase also depends on the expansion of a single product. China created only 27 varieties of species, species grade, quality, compared with developed countries there is a big gap. Basic research is weak, insufficient capacity for new product development.
            3 product structure needs to be further adjusted. Methamidophos has been completed in five kinds of highly toxic organophosphate pesticide reduction and substitution, as well as tert-parathion, phorate, methyl isofenphos varieties are still high-toxic pesticide production and use, these highly toxic pesticides varieties need to be further reduced and replaced. Pesticides, herbicides and fungicides ratio still needs to adjust the needs of agricultural production, fungicides a relatively small (only about 10%), especially for fruits, vegetables and other crops, fungicides less variety.
             4 reduction and heavy task, the lack of effective means of disposing of waste disposal. Pesticide manufacturing by-products and unreacted raw materials, low recovery rate, high water salinity, high concentrations of biodegradable organic pollutants, some of the specific pollution factors means the lack of effective treatment. Most of the original drug manufacturers do not have the ability to deal effectively with specific pollutants. EC and other preparations containing toxic organic solvents is still more environmental problems can not be ignored. Pesticide packaging waste recycling has not been fully carried out.
   Second, the trend
            From an international perspective, with the United States and Europe increasingly high environmental standards, as well as more details of the international division of labor, developed the original drug and the manufacturing capability to gradually transfer to developing countries, international pesticide in domestic construction of large companies have wholly-owned, joint venture and research institutions, China's pesticide industry is both an opportunity and a challenge, one of leading enterprises can take advantage of foreign advanced technology to enhance their skills on the other hand the impact of weak competitiveness of domestic enterprises. With the development of pesticide technology. In addition, the EU's "Registration, Evaluation, Authorization and Restriction" (REACH regulation) and anti-dumping litigation will be China's pesticide exports have been affected.
            Domestically, international pesticide giant has been the continuation of "Zhuanli pesticides - huge profits - R & D investment - new patent Nongyao" development path, while most domestic enterprises in the imitation stage, has created new varieties of intellectual property is still in the initial stage. Pesticide industry, the macroeconomic impact is less than the demand by the general chemical products, while agricultural demand for pesticides under the influence of the major pests and climate is directly related to the other country for the protection of agricultural production will increase investment demand for pesticides and secure. In addition, with the rapid economic development and rising living standards, environmental protection and people's growing awareness of food safety, pesticide production process "wastes" emissions continue to increase supervision of agricultural pesticide residue limits established by the standard will become more stringent, the layout of the pesticide business, new product development, new technology and put forward higher requirements. China's pesticide industry, industrial upgrading, will accelerate the pace of mergers and acquisitions, pesticide production will further large-scale, intensive direction, toward the high pesticide products, security, economic and environmental-friendly direction.
Third, the guiding principles and development targets
             (A) guiding thoroughly implement the scientific concept of development, to further adjust the industrial layout and product mix to meet the needs of agricultural production and enhance food security support capabilities, accelerating technological innovation, promote industrial upgrading and industrial concentration, improve product quality and grades, the implementation of circular economy, reduce environmental pollution, increase resources, comprehensive utilization of energy, improve waste disposal management, to improve the international competitiveness of the pesticide industry, pesticide industry to promote the long-term stable and healthy development.

Japanese rice fields floating granules (herbicides) demonstration test

2011-08-01T22:52:00.001-07:00

This is a Japanese rice field with a floating granules have been recognized for the commercialization of products in circulation, is a friend asked additives sent from Japan! By the collapse of trials found in the water, and our country are studying the floating granules (effervescent type) or have some differences:

    1 Japan's floating agents like to emphasize its floating nature, always floating on the water. And "wet" as if the two concepts, floating particles are wetting agent is not sinking;

    2 particle disintegration and rate of spread in the water did not imagine the fast, stir in the water even in the case, there was no collapse of drawing the trailing phenomenon, only the slow disintegration of the water separation. Likely to use in paddy fields, when the final requirements to be evenly spread out.

    3.A and B the difference is not great. Type B is introduced in accordance with the first sink and then float, a little effervescent mean!

    4 bags of soluble fast, have seen a lot of domestic capacity bags can be done, but have not seen such a good solubility.

     5 Finally, the color of floating debris is not pure white, I feel should be used for packing plant sources.

     6 At present, the additive has began to promote in the country, and some manufacturers have registered and engineered a number of products, rice fields in the Northeast a good market feedback. In fact, the Northeast market really has a lot of rice fields have the technical characteristics of small applied a good variety of dosage forms, there are bottles of spilled drops before with good results.

    7 formulations in the labor savings, it should be this large a dose "use features."

    8. A description: The original form is a liquid has a solid, liquid chlorine acetamide original drug to the original drug-based.

Attention! New Foreign Trade e-mail scam

      We do lazy sofa, mattress sets foreign trade factory, recently, we have a factory to do the Spanish guests goods, the product is successfully completed out of stock, had shipped about 10 days, the guests and I said on MSN Let them arrange the balance to us as soon as possible, because our ship received the guests feel like satisfied guests very readily agreed to pay the balance to us, and not two days after I contacted the guests, the guests have been honest very good, before we always chat on MSN, including the case of orders which are to communicate on MSN, and occasionally send email.

   After about three days, guests sent messages from MSN and asked me how is it? ? I thought to myself, this guest Zhendou, goods are out, it is difficult to have any other questions? Can not be the product of the problem, a large cargo ship has not yet arrived Yeah, I say how the matter? Guest said: your bank account change it? We are a small factory, a are all export and foreign trade companies, and our foreign trade company can not we do not know where to change the bank account, then sent me a lot of guests text message, the content is generally said To a reasonable tax avoidance, the guests hit the money to another account, I searched all my mail, I do not give guests two days of email records, suddenly my heart felt very wrong, the guests received the day after I sent e-mail address through their bank account, the account is in Singapore. We called the police, the police said they can not control international, and what we are victims.

  Means to expose a liar:

  I had been given the message by touching imitation consistent format, and I like to use Gmail mailbox to send a message my guests, it is really like, most people will not see it, let the guests to another exchange account is the balance of the order , e-mail the following contact information and phone numbers are similar with and my hair in the past, following a telephone contact we tried it, is to open up the mobile phone, mobile phone number displayed in Tianjin.Guests to give back to my correct email address but I could not receive.Fortunately, however, my guests and I am sure a bit, or really by these shameful liar defrauded of our hard-earned money.

   I did not find the problem, how do you know our guests is completed the balance of the order the specific amount, by the way what kind of information to know why I made the right guests and I can not receive mail? ? ? If a hacker I think we will not steal the information of this small factory, and I now really want to call in the past accused the liar! ! ! !

Main weed of farmland

2011-06-10T00:53:00.001-07:00

I. Occurrence of weeds
1, fast growth: the use of light, water and fertilizer than crops, the ability of strong growth of the asexual reproduction of the weeds very fast, compared with earlier partial mature crops.
2, more solid, continuous strong resistance, floor: It can produce 1-3 generations, tens of thousands - hundreds of thousands of seeds, ripe seeds fall off the general is likely to result, causing soil infection. Weeds take up space in the short term, covering the ground, because a greater amount of seed per plant. As thousands of times to generate weed seeds, weed control measures are effective even if a few thousand plants per acre of farmland weeds in the year left, can produce tens of millions or even hundreds of millions of seeds, next year's still a serious place.
3, seedlings mature mixed: weed seeds, crops mature earlier than the maturity stage is also inconsistent, usually flowering side, while strong, mature side, with the maturity of the field scattered with the loss, breeding several generations a year. For example, small pigweed in the Huang-Huai River Basin in late April each year to early May flowering, fruit ripening in late May until October still flowering and fruiting. Therefore, these weeds in the wheat field, Akita, vegetable fields and orchards, such as different field or have occurred in different seasons.
4, the weed seeds are ripening more features, some are flowering weeds are removed, the fertilized ovules can develop into seeds. Some post-weed, barnyard grass, such as rice paddies, fruit ripening rice generally higher than 10 to 20 days in advance. Wild oats in wheat, Alopecurus, sophia mature wheat and other weeds usually fall off before the fruit has matured. Most of the seedling weeds is not neat, such as shepherd's purse, pigweed, chickweed and other weeds in addition to January the coldest and the hottest August 7 does not occur, the emergence of flowering all the year round. Digitaria sanguinalis, Setaria viridis, Eleusine indica, Eragrostis, iron, amaranth, and black nightshade, etc. 4 August emergence could grow corn, cotton, soybean, peanut and other autumn crops and vegetable fields and orchards of the main weeds. Each field in a pouring rain one drop of water or weed emergence will have a peak, it is easy to form grass weed shortage of farmland and difficult to remove the main reason, but also to Control in inconvenience.
5, long life (sleep): cress seeds life of 40 years, field bindweed can survive for 50 years.
6, plasticity, and stress resistance: the ability to survive under adverse environmental conditions and adaptation is more prominent, have a greater priority than the crop type.
7, a variety of reproduction and pollination ways: asexual reproduction by seed or root, stem, bud propagation, different flowers can be both self-pollination, by wind, insects, animals, people can be pollinated.
8, a variety of modes of transmission: the seed by wind, insects, animals, livestock, water, agricultural machinery, irrigation, farmyard manure mixed with crop seeds, grain.
Mimicry of: such as millet and rice, and millet Setaria similar morphological and physiological behavior, labor and machinery than grass is very difficult.
Second, the harm of weeds
1, and crop competition for fertilizer, light, water, space: weeds have developed root system, stem node prostrate on the ground can take root, strong absorptive capacity, seedling stage of fast growth, photosynthetic efficiency, the product quickly to the new leaf photosynthesis conductivity distribution, and rapid vegetative growth to reproductive growth transition, with a special performance of the crop interference, capture water, nutrients and sunlight is much greater capacity than the crop. Has superior growth characteristics and prominent environmental adaptability.
2, lower crop yield and quality: poison mixed with wheat after wheat, ground into flour poisoning effect on people, people if eaten can cause dizziness, coma, nausea, vomiting, diarrhea, cramps, severe cases can cause death. Livestock poisoning from eating a certain amount of feed wheat, the same can cause poisoning or death. With barnyard grass in rice will reduce the grain quality, the meter rate. Overgrown orchard fruit color and quality is also affected.
3, impeding agricultural operations: if the wheat in Galium aparine, sophia, Cephalanoplos profusion of barnyard grass in rice, amaranth Monochoria more grass and water, the crop is easy lodging of grain weight, reduce the yield. Rice lodging, the harvester can harvest. Soybeans, corn in large velvetleaf, serious weeds, harvesting grass easily blocked failure. In addition, if the harvest is mixed with more difficult to dry grass, prone to mildew, resulting in losses.
4, the breeding of pests and diseases (intermediate host): If the mass poisoning of plants, some weeds virus transmission by insects infected with the virus, then the insects spread the virus on to weed crops, and thus become pathogenic virus disease occurred in one of the important ; aphids in the thorn vegetables, shepherd's purse and other winter weeds; barnyard grass is planthoppers and leafhoppers in the middle of the host.
5, the impact of human and livestock health: Toxic wheat flour led to more than 4% of people were poisoned or even death; livestock poisoning from eating a certain amount of feed wheat, the same can cause poisoning or death. Therefore, the drug was listed as the national wheat quarantine. Cattle eat feed with wild oat seeds, often caused by the mouth, esophagus and gastric mucosal inflammation; ragweed pollen can cause allergic symptoms were sensitive.
6 of water conservancy facilities and river navigation: the canals, slowing water flow, sedimentation, and provide habitat for the rodent nesting conditions for the dam damaged.
Third, the classification of weeds
Weeds: Africa is the cultivation of agricultural plants, agricultural plants more harm than benefit. There are 50,000 kinds of weeds in the world, of which there are 5,000 agricultural weed, China has 580 kinds of agricultural weeds.

Alternanthera: also known as water, peanuts, Amaranthaceae Alternanthera, perennial or annual herbs, mainly in winter stems and leaves, shoots mainly asexual reproduction, distribution, the southern provinces of China; infestation of rice, vegetables, cotton, orchards and lakes, a moist The main regional crops refractory weeds.
Six main Cyperaceae weeds:
Cyperus rotundus: also known as sedges, perennial herb, underground tubers, or nuts breeding, to grow a few roots, extend and grow tubers, the roots and tubers, breeding fast. June-July 8-October flowering seed. Located in the South, East, Southwest and other places, against peanuts, cotton, soybeans, vegetables, orchards, and other pests, or planthopper host. Shaped sedge: Cyperus spike the ball, also known as, seed breeding, annual herbs, seeds, small and light, can be scattered with the wind, with water rafting, or with the seeds, spread of animal activities; occur commonly, especially in low-lying paddy fields serious harm.
Cattle blankets: also known as ox hair grass, creeping underground rhizomes with a very thin, rhizomes and seed propagation, burning the body, although small, highly reproductive, spreading rapidly; distribution of the country, seriously affecting the growth of rice for weed.
Ying Lin: also known as small water onion, seeds and roots fan plants, perennial herbs, seeds spread by water; distribution of the country, against heavy weeds in paddy fields.
Flat bar standard grass: also known as Tri-grass, perennial paddy weeds, roots and seeds to reproduce, life 5 - 6 years, almost all over the country, is a rice field weed.
VII Weeds measures:
1, agricultural measures
A crop rotation: cropping system, crop rotation; rotations, crop rotation and the rotation period of different combinations on weed communities in different degrees; human impact of the succession of weed communities.
B deep plowing farming: plowing (turning ridge, flat turn with; deep plowing, shallow plowing alternate), V turn, turn autumn, autumn plowing.
C Selected varieties: a variety of weed seeds vary widely, that is the same weeds in different ecological conditions, seed size is also inconsistent. People mainly use the weed seed size, weight, there is no Mount Mount, smoothness, different floating ability, mechanical, wind, sieve, water and workers in the seizure, removal of the weed seeds, leaving no seeds, no The full robust grain pest species, as used to reduce the spread of harmful weeds, reduce pests and diseases, increase crop yield.Others in the field for chip select, plant ear election or elections, specifically the selection criteria for disease-free ear of robust, without any weed seeds, after singles by species as a seed to give full play to the advantage of two to reduce the complexspread and damage the grass. For example, to prevent the spread of the spread of wild oat, wheat and wild oat take full advantage of different seeds, and wind sifting election, removing a large number of wild oat seeds and other seeds, to prevent the spread of the spread of weeds. In the post-harvest seed for soybeans, soybean dodder seeds are often mixed in the seed, the use of dodder seeds of soybean and soybean of different sizes, with the screening method can clear out the soybean seed Dodder, Cuscuta reduce the spread of soybean spread strains up to 80-90% control efficiency. Soybean Seed plots, a long weed velvetleaf, you can unplug the velvetleaf (immature seeds), and finally closed breeding fighting reserved. Featured weed plant and seed varieties, is an important method to reduce weed infestation.
D Composting: the eradication of organic fertilizers important means of seeds.Organic fertilizer is the main fertilizer sources in rural areas as farmland, but also the root causes of the spread of weed spread. Complex when the sources of raw materials as manure, not only straw, leaves, green manure, garbage, etc., but also with weeds manure, contains a lot of weed seeds inside, without a lot of seeds in high-temperature composting again into the field, to complement and increased the number of weeds, not composting and fertilizer containing weed seeds occur leading to serious Weeds One of the reasons, in the production of this issue should be high priority, high-temperature composting to kill weeds is to prevent the weed seeds an important part of hazard.
E high-density planting: In the Weeds Control in the measures, often using plant height and density of shading effects to control and eradicate weeds, namely, "the grass seedlings bully" and "high-control grass", "to close off grass. "
Stalk crops such as corn, sorghum, sugar cane, most of the height of weeds in these crops lower than 80% to 90% of the weeds growing in the lower part of these crops.Stalk crops compete with weeds in the process, the occupied space, is the absolute advantage in crop photosynthesis, growth flourish. The weed grows in the lower part of stalk crops, occupying less space, light is poor, few see the light, photosynthesis was inhibited, so that weeds are very little nutrients, resulting in weak growth or death of hunger.
Induced by late sowing F: is the use of the biological characteristics of crops and weeds growth characteristics, organized and planned delayed crop planting, so that early weed unearthed, Control weeds before sowing method. Using this method can be directly targeted prevention and elimination of weeds, weeding received good results.
G management of water:
2, Plant Quarantine:
Quarantine regulations is to prevent the spread of weeds and effective communication methods. Quarantine objects such as ragweed, poison wheat, wild oats, dodder seed, sorghum and other highly hazardous to human, livestock, crops, weeds, and more frequently transferred from the kind of process, should be prepared in all aspects of quarantine and the quarantine, so that specialized seed production, processing, mechanization, quality standardization, qualification of varieties and management professional.
3, cultivation, weed: targeted, clean and thorough, simple technology, not only Control in weeds and crops but also to provide good conditions for growth. In the crop growth throughout the process can be repeated as necessary cultivation, weed,
Including: manual eradication, mechanical cultivation, weed and can promote plant growth while herbicides.
4, biological weed control: the use of biotechnology, including fungi, bacteria, viruses, insects, animals, nematodes, weeds and grass grams of grass and weeds using different strains of the role of such content.
Microbial Control in: One control soybean Paul Lu Dodder, F793 bacteria (a Fusarium) Control in melons Orobanche weed Control in such a way fungi;
Insects, animals Control in: ducks, such as rice, can eat some grass weeds in bud; use of geese in the sunflower fields, tobacco feeding parasitic weed Orobanche Tanaka; the western United States to introduce a beetle eradication of Hamas pasture grass, wing tip of a small internal volume has been found that Cyperus rotundus moth's natural enemies, can be spotted feeding on the water Potamogeton borer, living insect eats the negative mud Commelina Weed Control in insects are all methods used.
5, chemical weed control: Weed Control in short chemical herbicide. That the growth of crop and weed characteristics and laws of the type of chemical herbicides and the role of the principle of plants, the impact of various factors on herbicide and the technical requirements in the use of weed Control in the method proved herbicideweed control method is a modern method, which is to eliminate agricultural weed, crop production to ensure that important scientific instruments, has achieved remarkable economic and social benefits. Its characteristics are:
(A) weeding fast and efficient. V-type or motor with a back sprayer manual weeding weeding several times faster, respectively, compared to several hundred times a day aerial spraying herbicide spraying area of several hundred hectares.
(B) effective weed control, pesticide application in due course, one can solve weed spraying, and then people do not need to unplug. With 12.5% of Gallant Control in peanut, soybean, onion Tiandan cotyledons weeds, the control efficiency of 95% to 100%; with 45% of the fear of Control in soy beans, grass weeds up to 95% to 100% of malignant mixed Grass velvetleaf, morning glory, sedges and other effects of 90% to 95%. After application to weeds or the newborn period nipped in the bud, but also between strains of weed control is also relatively clean.
(C) yield significant results. Chemical weed control than manual weeding generally yield about 10%.
(D) of rainfall can not be overcome by manual weeding and mechanical weeding of shortcomings. Manual weeding and mechanical weeding is not carried out in the rain, rainfall after herbicide herbicides on soil moisture content just to meet water requirements, weed herbicides full effect.
(E) Chemical weed control is conducive to integrated control of pests and diseases.Timely elimination of chemical weed control weed, pest removal and cut off some of the intermediate host, wintering sites, as virus hosts, hobbies host, thereby reducing pest damage. Such as the elimination of Alopecurus, wild oats, crabgrass, chickweed, etc. to remove or cut the wheat aphid, Aphis binary intermediate hosts and yellow dwarf disease, scab virus transmission medium.
(F) is conducive to the reform of farming systems. Such as zero tillage, minimum tillage method, planting and reduce the spacing to improve air density, chemical weed control can only solve the shortage of grass, the crop from damage, this alone is difficult to implement manually removed.
(G) in favor of mechanization. Weed Control in a large area, such as when the mechanized spraying, weeding effect, fewer weeds, more conducive to mechanized harvest.

Plant growth regulators to a more rational use of scientific knowledge to

2011-06-06T23:47:00.001-07:00

CCTV 2 this evening of food safety press conference on the "terms of pesticide residue" by the Institute for Drug Control Po-kan, director of care as a pesticideexperts to answer the concerns of the media and consumers, in terms of agriculturalresidues to answer media questions and answers, the impression is too deep , Andbanana ethylene toxicity than table salt, is Forchlorfenuron toxic than table salt, andexcessive use is not much good, very clever answer.

Source: Pesticide Information Network

    This year, the domestic consecutive on "banana ripening ethylene harm to human health" as well as untrue reports "led to the leavening agent watermelon explosion" and "hormone cucumber" over-exaggerated, so that the application of plant growth regulator is being questioned. Not only caused panic consumers, but also to the supply of agricultural products and farmers income as well as plant growth regulators industries, adversely affected. The participants believe that the phenomenon, has complicated reasons, the current mainly in the following four areas:
    First, the lack of plant growth regulator application on the positive publicity, the public lack of plant growth regulators on the correct understanding, in case of false media reports, it is easy to panic in the community.
    Second, in the practical application of plant growth regulators, the error still exists use, excessive use and inappropriate use of time to technical problems, the use of not only difficult to achieve the desired effect, but also give farmers a significant economic losses.
    Third, some pesticide or plant growth regulator production enterprises, will be registered or not registered in the name of fertilizer products directly to the market.Some of these products not only of poor quality, but also in product identification and description is often used to expand the scope of exaggerated use of effects, easy to mislead the farmers, agricultural production hazards in the same time, the quality of agricultural products will also become a security risk.
    Fourth is the business of plant growth regulators are mostly generic production of foreign products, and less self-created formulations behind the product, it is difficult to meet the needs of agricultural development.

Comparison of the recent media and consumer attention to the problem of plant growth regulator, the Information Office of the Ministry of Agriculture today announced the press conference, in order to enable the public to the scientific understanding.Chinese Academy of Agricultural Quality Standards and Testing Technology Research Institute researcher Ye Zhihua, said in response to a question, plant growth regulators to a less toxic products, in accordance with the "Pesticide Management Regulations" provisions are of pesticides plant growth regulator the scope of management, it is only through licensed pesticide registration and access to the production of plant growth regulator products in order to carry out production, management and use.
    Reporter: The recent media reports prickly cucumber flowers top the plant growth regulator "pink" and what is the plant growth regulator? Plant growth regulator on the market How many? How to use?
    A: The plant growth regulator for regulating plant growth and development of a class of substances. Plant growth regulator, also known as plant hormone, usually through artificial synthesis or microbial fermentation produced, their physiological role and biological effects and the natural plant hormone (a naturally occurring plants compounds) the same or similar.
    Currently, the plant growth regulator widely used in the world agroforestry production, foreign varieties have been commercialized than 100, mainly ethylene, a piperazine onium, CCC, Thidiazuron, gibberellic acid, applied include vegetables, fruit, cotton, tobacco, rice, wheat, corn and soybeans and other crops. Registered for use of plant growth regulators in 38 varieties, commonly used are ethylene, gibberellic acid, nearly 10 varieties, mainly in horticulture, rice, cotton and other crops used.China has registered for use on cucumber varieties Thidiazuron, Forchlorfenuron, nucleotides, brassinolide, sodium nitrophenolate, NAA, IBA and other seven species, the main role is to promote the growth of female flower to improve fruit set and so on.
    Plant growth regulator as a less toxic products, if approved in accordance with national registration to use on the label and precautions to use, is safe. The use of plant growth regulator, not only to protect crop yield, improve the quality of agricultural products, but also can enhance the resistance of crops, so saving time and labor of agricultural production, efficiency of the section.
    Reporter: the state's use of plant growth regulators What are the requirements?
    A: According to the "Pesticide Management Regulations" provisions, plant growth regulators are the scope of pesticide management, pesticide registration and access is only through licensed production of plant growth regulator products in order to carry out production, management and use.
    Our very strict requirements on pesticide registration, application for registration of pesticide products need to be a lot of testing, from product chemistry, efficacy, toxicology, residues, environmental impact and other aspects of critical review and scientific evaluation, and only after scientific evaluation, proven good control effect, while human and animal health and environmental effects of controlled, consistent with protection of human health and environmental safety requirements, in order to obtain registration. Production and management of pesticides, to be approved by the relevant department with the label, clear and effective ingredients, and precautions such as use of the content. Plant growth regulator used in strict accordance with the use of labeled doses, the use of time and use of standard use, not abuse.
    Reporter: What is a plant hormone? Ripening of the fruit with the hormone will not harmful?
    A: The plant hormone is naturally occurring in plants on plant growth, a significant role in development of trace organic substances, also known as plant hormones or plant natural endogenous hormones. Its existence and effective regulation can affect plant growth and development, including cell growth, division, to take root, sprout, blossom, mature and fall off the whole process a series of plant life.
    Plant Growth Regulator is a natural plant hormone in understanding the structure and mechanism of action, the hormone through artificial synthesis and with similar physical and biological effects of substances used in agricultural production, effective crop fertility regulation process, to yield stable to improve quality, enhance crop resistance and other purposes.
    Registration of approval on the label by the use of dose, time and method of use of plant growth regulator will not cause harm to human health. If you are using does not appear on the standard, may cause excessive growth of crops, quality and taste of farm products will have some impact, but will not cause harm to human health.
    Reporter: The existing means of agricultural product quality safety supervision and can detect whether a plant hormone?
    A: The plant hormone into endogenous hormones and exogenous hormones. Only exogenous hormones (plant growth regulator) has detected problems. Approved for use by the state of plant growth regulator, has a corresponding detection methods.Agricultural products quality and safety of existing regulatory and professional testing organizations, all agricultural products with detection ability of plant growth regulator, can accurately detect whether a plant growth regulator, needs to be noted that, due to major in plant growth regulator supporting the use of plant growth process, the general public in a mature fruit or low residue products, sophisticated analytical instruments required for accurate quantification.

Avermectin pesticide processing problems and development direction

2011-06-02T18:14:00.001-07:00

Conference Introduction

      Avermectin antibiotics as a new biological pesticide, since the market has by virtue of the new structure, efficiency, safety, livestock and other characteristics of dual-use and popular, through its structural transformation of a series of activitieshave developed a more High, more selective, better security, new varieties ofderivatives. With the highly toxic pesticides out of the market, and abamectinapplications in rice, the market demand for avermectin increased significantly.

      Development opportunities in that same time, we also see there are a series ofproblems avermectin. Such as drug resistance, complex means of waste watergenerated in the production process, residue treatment, which are seriously restricted the development of avermectin, leading to price volatility.

     Avermectin industry opportunities and challenges, market competition is heating up.
