First, the use of high-efficiency and low-toxicity pesticides It is strictly prohibited to use highly toxic and high-residue pesticides, such as 1605, 007 omethoate, formazan, etc., use high-efficiency, low-toxicity, low-residue pesticides such as carbendazim that have a low lethal effect on natural enemies. Chlorothalonil, cymetoxon, mancozeb, crocetin, etc. Second, the choice of production base Pollution-free vegetable production base to stay away from industrial and mining sources of pollution, to avoid "three wastes" pollution, environmental quality in line with DB221-946-2001 regulations. Third, the selection of species selection of disease-resistant pests, high quality and high yield, strong resistance, good product performance varieties, such as the protection of cucumber varieties can choose green number one, Jinchun series, eggplant varieties can choose to use Jige two, black Bright and so on, pepper varieties can choose Baojiao, Zhongjiao No. 4 and so on, tomato varieties can choose Jifen No. 3, Jiafen 15 and so on. Cucumber varieties can be exposed in the open use Jiza No. 2, Jiza No. 4, green pepper varieties can choose Jijiao No. 2, Jijiao No. 3, etc., Eggplant varieties can choose to use Shen Wei, No. 2, Jigen No. 1 and so on. IV. Pest Control 1. Agricultural Control: Before planting, we must remove stubble leaves, weeds, and diseased plant residues from the field, and transport them out of the field to be buried or burned. Avoid non-undergraduate crops for more than 3 years of rotation, avoid heavy-duty, black-seed pumpkin as an anvil graft and other measures to prevent pests. 2. Biological control: Use natural enemies, such as the use of licorice bee to prevent greenhouse whitefly, use biological pesticides to prevent pests and diseases, 2% wumaimycin agent 200 times solution to control cucumber anthrax, 4% of kasugamycin wettable powder 1000 times liquid to prevent cucumber bacterial angular spot, Bacillus thuringiensis WP 2.25 kg / ha foliar spray can control aphids, spider mites. 3. Physical prevention and control: The use of yellow plates to induce fleas and silver-gray membrane strips to prevent and control aphids, set insect nets or shade nets to prevent insects, high temperature stuffy sheds, and the temperature in the shed reaches between 42 and 45°C for 1.5 to 2 hours. Cucumber downy mildew, warm soup soaking with 50 ~ 55 °C warm water soaking for 20 minutes up to the seed disinfection. 4. Chemical control: Do a good job in predicting and forecasting pests and diseases, and prevent them in advance. Appropriate doses of appropriate drugs and chemical agents should be used to prevent and treat disease at the right time, depending on the severity of the disease. In the initial stage of disease, spray once every 7 to 10 days, and even prevent 3 to 4 times of the same pesticide species. Can not be used continuously for 3 times, should be used interchangeably. According to the different types of bacteria, the disease can be controlled by the corresponding pesticides. 72% Kelu, 69% Ankang Zinc, 75% chlorothalonil, 70% Mancozeb, 50% carbendazim, 50% thiophanate-methyl and other wettable agents to prevent downy mildew, disease, anthracnose and other fungal diseases, use 72% of streptomycin sulfate in agriculture, 77% can kill WP, 30% DT WP to prevent bacterial leaf spot disease and other bacterial diseases; use 5% bactericidal WP 20% virus A WP to prevent viral disease. Select 1.8% insects Manchurian EC, 1.8% piroxol WP, 50% phoxim 2.5% Chlorine, Argon, Cyanide, Chrysanthemum EC, and 2.5% Deltamethrin EC to control pests. Fifth, formula fertilization should be made more decomposed good manure, pig manure mixed fertilizer, preferably biogas residue, due to different types of vegetables and fertility, the amount of fertilizer is also different. Strictly control the amount and type of chemical fertilizers, potassium fertilizer should be applied with potassium sulfate fertilizers, potassium chloride fertilizers should not be applied, nitrogen fertilizers should be applied with ammonium nitrogen or ammonium phosphate fertilizers, nitrate nitrogen fertilizers, and the amount of fertilizers used for solanaceous fruit should be strictly prohibited. 300 kg of hectares of phosphoric acid diamine and 50 kg of potassium sulfate. After flowering, the fruit began to top-dress after fruit enlargement, followed by the organic fermentation of fermented and fermented 1 or 2 times. In the production of pollution-free vegetables, reduce the amount of chemical fertilizers, and use more biological fertilizers, such as fruits, Tianda -2216, etc., pollution-free bacterial fertilizer in the fruit and vegetable excrement in the period of the thunderbolt, young fruit, and fruiting period Spraying once can increase production by more than 20%. Six, strictly control the safety interval of pesticides used in different intervals of different safety intervals are not the same, 3 times permethrin, chlorothalonil 7 days, 25 days fast-king, mango manganese 10 days, timely vegetables quality The test ensures that when the vegetables are on the market, the pesticide residues do not exceed the relevant standards, and timely harvesting is performed after the safety interval. The tools used for harvesting should be clean, hygienic, and free of pollution. Author unit: Huiyang County Chaoyang Town Agricultural Station
