Vegetables make people's daily necessities, if there is residual pesticide adhesion on the surface of the leaves, it will directly affect people's health. In severe cases, the consequences of poisoning events will be unimaginable. Therefore, it is necessary to be cautious when applying bio-pesticide on vegetables. Here are three things to note:
1. Pesticide varieties Generally, pesticides cannot be applied randomly after the occurrence of pests and diseases. When pesticides must be applied, they should be applied according to national regulations: highly toxic pesticides and pesticides with long residual period are not allowed to be applied on vegetables, and only high-efficiency and low-toxicity can be applied. A pesticide that is easily decomposed and has a short residual period. It is necessary to select the right-handed variety from the pesticides such as dimethoate, phoxim, methyl thiophanate, carbendazim, triadimefon, and streptomycin sulfate.
Second, the amount of concentration and the concentration is too large will not only cause phytotoxicity in vegetables, but also easily cause personal poisoning. China Pesticide Network reminds that when using pesticides, it must be in accordance with national regulations: when applying 40% dimethoate emulsion, the dilution concentration is 800-2000 times liquid spray, the amount of mu should not exceed 0.1-0.2 kg; when applying 80% dichlorvos emulsion, the dilution concentration is 500-2000 times liquid spray, the amount per mu should not exceed 0.2-0.4 kg.
Third, the time to stop the application of pesticides on vegetables, must stop using drugs 10-25 days before harvest, especially with organophosphorus pesticides, such as malathion, phoxim, dimethoate, etc., should be strictly controlled, otherwise It is easy to cause poisoning in life.
Pesticide manufacturers remind everyone to strictly control the above three levels, to achieve scientific and rational use of drugs to improve drug efficacy, to avoid the occurrence of pesticide safety accidents.
