Status Analysis Of Insecticide Industry
Sep 21, 2018

1. The development requirements of new insecticides are getting higher and higher.

In recent years, the development direction of foreign pesticides is high efficiency, low toxicity, low residue, non-pollution, especially pesticides, embodied in the pursuit of "three high": high safety, which not only requires low toxicity, low residue, but also requires biodegradable, pollution-free; high bioactivity, the effective dose of newly developed compounds are mostly low-use. Quantity; high selectivity, almost all new varieties have a specific mode of action. The three high inactivity to crops other than target pests, beneficial insects are based on a common ground, that is, to protect the environment for human survival. In addition, in the development of new insecticides, it is also required to further reduce production costs.

2. Biogenic chemical synthesis has become the main way to develop new insecticides.

Since the 1980s, the development of traditional synthetic pesticides has become more and more difficult. The rapid development of modern technology and the improvement of biological science theory have promoted the development of synthetic pesticides based on natural active substances. Biogenic synthetic insecticides are natural toxins as lead compounds. After structural modification and optimization, new compounds have been developed. The success rate of this method is relatively high, and it has become one of the main ways to develop new and efficient insecticides. For example, pyridaben was developed from nicotine and chloronicotine, pyridaben was developed from rotenone and rotenone, and bromoconazole was developed from pyrrolidone.

3, high toxicity and high residue insecticides will be further restricted.

In recent years, due to improper application of highly toxic pesticides, human and livestock poisoning incidents occur frequently. In addition, some countries and regions exceed the scope, exceed the standard, abuse of high toxicity and high residue pesticides is very serious, which has brought serious harm to people's health and safety, but also destroyed the wildlife resources, and has a great impact on the ecological environment. For this reason, many countries and some international organizations have enacted laws to prohibit or restrict the use of high toxic and high residual pesticides. For example, the United States promulgated the Federal Food Safety Act, which requires a comprehensive risk assessment of each pesticide, including organophosphorus and carbamate. The Food and Agriculture Organization of the United Nations and UNEP have formulated the PIC Convention, which imposes import and export restrictions on 22 pesticides, including four highly toxic organophosphorus pesticides. The European Union has issued a directive to enforce the maximum residue limits for 108 pesticides in tea, most of which are pesticides and the most vocal are pyrethroids. Therefore, it can be foreseen that with the increasing awareness of the protection of human living environment and natural ecology in the world, high toxicity and high residue pesticides will be further restricted, not only more and more banned species, but also the banned scope will be more and more widespread.

4, the market potential of developing highly toxic insecticides to replace varieties is huge.

Sustainable development strategy is changing the structure of the world's pesticide industry. It restricts the production and use of high toxic and high residue pesticides through various regulations. It also provides new opportunities and markets for environmentally friendly pesticides. According to the Pesticide Outlook, the total value of the pesticides to be replaced is more than 9 billion US dollars, including 3.3 billion US dollars for high toxic organophosphorus compounds and 1.5 billion US dollars for high toxic carbamates. At present, the production of high toxic organophosphorus pesticides in China is very large. According to the Tenth Five-Year Plan, the total output of five high toxic pesticides (methamidophos, parathion, methyl parathion, Monocrotophos and phosphamide) will be reduced from 120,000 tons to 20,000 tons, and will be suspended nationwide from January 2007.

In addition, the Ministry of Agriculture has recently begun to restrict the use of omethoate, methamidophos, isocarbophos, terbutamidophos, methylthiocyclic phosphorus, borer control phosphorus, methylisosalicylphos and endophosphorus as well as aldicarb, carbofuran and methomyl carbamate pesticides. This will provide a huge market for the development of high toxic insecticides in China.

5. High efficiency and low toxicity insecticides will be used more and more widely.

In recent years, high-efficiency, low-toxicity and low-residue insecticides have developed rapidly all over the world, and new products have been developed successfully and popularized rapidly, such as imidacloprid, acetamidine, thiamethoxam, thiabendazole, thiamethoxam, fipronil, acarid ester, imidamide, bromoconazole, pyrazinone and acetamidazole. As well as insect growth regulators in lice mite urea, pyrifos urea, fluorourea, difluorocarbamide, tebufenozide, formyl hydrazine, cyclohexanone, pyridinone, pyrrolidone, spironoid, etc. Because of their novel structure, unique action mechanism, high biological activity, environmental friendliness and resistance, these new varieties have gradually replaced high toxic organophosphorus pesticides and become an important part of pesticides. Compared with heterocyclic insecticides, insect growth regulators have narrow activity spectrum and poor quick-acting, but insect growth regulators are environmentally friendly, especially suitable for sustainable agricultural development. At the same time, it should be noted that the introduction of heterocyclic structure and fluorine atoms in the development of insect growth regulators has shown good prospects for development.
