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

Japanese rice fields floating granules (herbicides) demonstration test
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.
