I. Industry Overview of Pesticide and Pesticide Intermediates Pesticide refers to the chemicals used to control pests, weeds and pathogens that harm crops. The complete pesticide industry chain consists of three major sections: pesticide intermediates, pesticide technical synthesis and preparation processing. The upstream of the industry is yellow phosphorus, liquid chlorine and other inorganic raw materials and the basic end of methanol chemical industry, benzene chain production of three industries, etc. The organic raw materials are refined materials, and the detailed chemical industry is agriculture, forestry and animal husbandry, and the industry is related to biotechnology. The field of obstetrics and health dependence is large. The total investment in research and development is said to be large, and the industry is long-term in the agricultural and pharmaceutical period. The risk is high, and the success rate is low. The pesticide industry is one of the important industries supporting agriculture. Under the contradiction between the global population growth and the reduction of arable land, the widespread application of pesticides to increase the yield per unit area is an important way to solve the food problem. However, the use of pesticides also poses a direct or indirect threat to the environment and human health. Therefore, with the enhancement of environmental awareness, more and more attention has been paid to the toxicity and residues of pesticides. direction of dosage. Therefore, the strategic significance of the research on the structural adjustment and investment optimization of the pesticide industry is extremely important. my country's pesticide industry started late. Although a complete industrial chain has been established, there are still many layout problems, especially driven by the national strategy of "going out" and the deeper "coming in" of the world's pesticide giants. The pesticide industry, which is a basic agricultural industry, has more prominent contradictions in the industry. At this time, the research on the development history of the pesticide industry in developed countries has strong reference significance for the healthy and sustainable development of the pesticide industry and agricultural related fields in my country and other developing countries.

2. The world pesticide market The consumption of pesticides is greatly influenced by the laws of agricultural production, the scale of crop planting and the planting structure. Affected by the seasonality of agricultural production, the production and consumption of pesticides also show obvious seasonality. In my country, the peak period of pesticide use is from March to September every year, so the first half of the year is also the peak period of pesticide production. In addition, pesticides are still important disaster relief materials and require quantitative reserves. Therefore, the production of pesticides in our country has the advantages of other countries, especially regions. Features such as the United States, which has a large span, do not have. In addition, the pesticide industry is closely related to national agricultural policies and changes in farming systems and technologies. my country's agricultural production is relatively backward. Therefore, we summarize the development curve of the world's pesticide industry, learn advanced experience, and introduce advanced farming technologies, auxiliaries, and pharmaceuticals. It has strong guiding significance. l. The market scale has shrunk since the pesticide industry began to boom in the mid-1990s. It was not until 2003 that the world pesticide market achieved actual growth in terms of product structure changes, and then gradually entered a sales market. During the period of stability, the sales have stabilized at about 31 billion US dollars in recent years. Under the guidance of the industrial policy of the "Eleventh Five-Year Plan" and the national strategy change after the successful convening of the 17th National Congress of the Communist Party of China, the income of farmers will inevitably usher in a The third growth period after the founding of the People's Republic of China. The transfer of agricultural labor to industry, the growing area of ​​economic crops such as fruits and vegetables continues to grow, and the increased investment in means of production will vigorously drive the growth of pesticide consumption. Combining with the world's industrial background, the world's authoritative consulting agency predicts that my country's agriculture will grow at a rate of 7% in the next few years, and the steady growth of international and domestic demand will undoubtedly provide sufficient impetus for the development of the pesticide industry. 2. The development curve of the world pesticide industry (1) The transfer of the market. The pesticide industry in developed countries started early, has passed the period of rapid development, and the market tends to be saturated. The growth of the pesticide market is mainly concentrated in China, India, some countries in the Asia-Pacific region and South America, and the agricultural development of developing countries will become the driving force for the growth of global pesticides. The production capacity of pesticides in the world is also being transferred to relevant countries in order to reduce costs and sell them nearby. Relevant enterprises in my country should seize this opportunity to introduce and absorb the production management experience of advanced enterprises to run the modernization of agriculture. ( 2 ) The development of pesticides develops in the direction of high efficiency, low toxicity, low residue, high activity and high selectivity. This is the main reason why the demand for pesticides in developed countries tends to decline. In the next few years, biopesticides led by Bacillus thuringiensis pesticide (Bt) (currently biopesticides only account for 1% of the entire pesticide market) will grow strongly at a rate of about 10%, but chemically synthesized pesticides are still The main body of the pesticide market.
