biological pesticides have the advantages of safety, no toxic side effects and no environmental pollution. It has become an inevitable trend to vigorously develop biological pesticides. Biological pesticides are an important guarantee for green food production. Developing pollution-free agriculture and producing green food is one of the national development goals. It has been clearly stipulated in China's green food production standards that biological pesticides such as Bt, Nongkang 12 and Jinggangmycin should be used in AA-level green food production. Beijing, Shanghai, Shandong, Guangzhou, Fujian and other provinces and cities have formulated pollution-free production regulations, which clearly prohibit the use of highly toxic pesticides and some highly toxic pesticides in vegetable production. In the next few years, five highly toxic chemical pesticides, which account for about 7% of China's pesticide use, will be withdrawn from the market and replaced by low-toxic biological pesticides.
In 26, the total demand of various biological pesticides in China reached 145, tons, and the total sales volume was about 8 million to 1 billion yuan. Bt pesticides in China account for only 2% of the market, cotton bollworm virus pesticides account for .2%, agricultural antibiotics account for 9%, and botanical pesticides account for .5%. In the next 1 years, biological pesticides will replace more than 2% chemical pesticides. There is a great demand for biological pesticides in China. The planting area of wheat, rice, corn and cotton in China is about 9 million hectares, and the planting area of vegetables and tobacco leaves is about 3.3 million hectares. Every year, pests such as Helicoverpa armigera, Plutella xylostella and Spodoptera exigua harm about 2 million hectares, and rice sheath blight, rice blast, bacterial blight, wheat powdery mildew, rust, scab, plant nematode disease and virus disease harm about 27 million hectares. Therefore, there is a great demand for pesticides. Therefore, the development potential of biopesticides in the future is huge.

Achievement name: Research and popularization of biological pesticides to control rice diseases and insect pests
This topic has found out the major changes of rice diseases and insect pests after the adjustment of agricultural structure in this city. Some major pests and diseases are rampant again due to the use of chemical pesticides, varieties and climate, and some minor pests have become major pests. Such as rice leaf roller, rice planthopper, rice sheath blight, rice blast and so on, have become the main pests and diseases. Chemical control is still the main measure to control rice diseases and insect pests. The control effect of biological pesticides on rice diseases and insect pests was studied, and the varieties of biological pesticides and the most suitable dosage were screened out to replace the chemical pesticides with high toxicity and high residue. Using biological pesticides to control rice diseases and insect pests reduces the environmental pollution caused by chemical pesticides, protects beneficial organisms in nature, protects ecological balance, realizes the sustainable management of diseases and insect pests, ensures people's health, improves people's quality of life and promotes the harmony between man and nature.

Project leader: Product name of Minhang District Agricultural Technology Service Center, Shanghai: Preparation and production technology of active oligosaccharide bio-pesticide
This achievement was successfully developed for the first time at home and abroad and applied to oligosaccharide bio-control pesticide for preventing and controlling plant diseases such as cotton verticillium wilt and soybean virus disease. It provides an effective biological pesticide for the prevention and treatment of cotton verticillium wilt and soybean virus disease. According to the requirements of the new pesticide registration regulations of the Institute for Pesticide Testing of the Ministry of Agriculture, two-year and multi-regional field experiments have been completed. Zhongke No.3 (Kaide) won the pesticide production approval certificate of the State Bureau of Petroleum and Chemical Industry (No.:HNP2179-D1992) on October 1, 2, and the temporary pesticide registration certificate of the Ministry of Agriculture (LS21533) on October 1 of the same year. During the period, it was repeatedly demonstrated by the State Planning Commission, and the industrialization project with an annual output of 5, tons of oligosaccharide biological pesticides was officially listed as a high-tech project of the State Planning Commission at the end of 2. The control effects of seed soaking treatment with Zhongke No.3 on cotton verticillium wilt and foliar spraying treatment on soybean mosaic disease are equivalent to or higher than those of conventional pesticides currently used. Because the action mechanism of this pesticide is different from that of traditional pesticides to inhibit or directly kill pathogenic microorganisms, it induces a new plant immune response, so it will not produce drug resistance, and has the characteristics of safety, non-toxicity and low dosage. Zhongke No.3 has adopted modern bioengineering technologies such as specific fungal fermentation, cell collection, bacterial powder enzymolysis, enzymolysis and membrane separation, and formed a mature, feasible, easy-to-scale technology and production route with independent intellectual property rights in China. The pilot test of 2L fermentor scale has been completed, and 128 tons of oligosaccharide biopesticide has been produced, which lays the foundation for industrial production.
