To cultivate pollution-free eggplants, it is necessary to take the prevention-oriented guiding ideology to treat the pests and diseases of eggplant. If pests and diseases occur, first of all, comprehensive prevention and control should be considered, such as the use of natural enemies of pests (Trichogramma, Ladybug, etc.) and the natural enemies of the bacteria. "(such as jinggangmycin, streptomycin, avermectin, etc.), and with other high-efficiency, low-toxic, low-residue, and environmentally friendly chemical pesticides. The first thing to do is to avoid using the following pesticides:
First, the production of pesticides prohibited: 666, D D T, insecticidal mites, fluoroacetamide, arsenic, Xi Lisheng, Sanli San.
Second, high pesticides: methamidophos, phorate (3911), bismuth phosphorus (Suhua 203), parathion (1605), methyl parathion (methyl 1605), internal phosphorus (1059), Killing carbaryl, phosphonium, isopropoxide, trithiophos, omethoate, acesulfame, chloropicrin, dibromochloropropane, 401, dihydropermethrin, methyl isoflavin.
Third, high residual pesticides: dicofol, chlordane.
4. Pesticides compounded with the above-mentioned high-level pesticides and high-residue pesticides: such as compounding and compounding with methamidophos and sulphate.
5. The registered pesticide varieties can be used without verification on vegetables.
Secondly, we must pay attention to the problem of safe interval of application: What is the safe interval for pesticide application? Pesticides can be gradually reduced to the allowable standard by the action of enzymes in vegetables, the action of soil microorganisms, the isomerization or cleavage of pesticides themselves, and photolysis and alkaline hydrolysis, especially under the influence of climatic conditions. The number of days between the medicine and the harvest date ensures that the residue of the harvested vegetables will not exceed the standard, which is called the safety interval. Generally, the temperature is 7-10 days when the temperature is high, and 10-15 days when the temperature is low. If the safety interval of the specific pesticide is not very clear, it is best to apply the last half of the month before the vegetable is marketed.
