Scientific selection of pesticides in the cultivation of pollution-free crops

1. Priority should be given to bio-pesticides. The biological insecticidal and acaricidal agents commonly used in production are: Bt, avermectin, Liuyangmycin, Huaguangmycin, anisole, rotenone, matrine, veratrine, etc.; fungicides are: Jinggangmycin, Chunramycin, polyantibiotic, Wuyimectin, agricultural streptomycin and so on.

two。 Reasonable selection of chemical pesticides. It is strictly forbidden to use highly toxic, highly toxic, highly residual, highly bioenriched, high-grade three (teratogenic, carcinogenic, mutagenic) pesticides and their compound preparations. Such as methamidophos, carbofuran, 1605.3911. Omethoate, chlordimeform, methotrexate, chlordimeform, methomyl, methomyl, zinc phosphide, methamidophos, methyl parathion, parathion, monocrotophos, organic mercury preparations and so on. Choose chemical pesticides with high efficiency, low toxicity and low residue. The chemical insecticides and acaricides that are limited to use are: trichlorfon, phoxim, dichlorvos, Lesbon, cypermethrin, deltamethrin, fenvalerate, propargite, dimethoate, nisolan, aphid fog, Yitabao, diflubenzuron, thiazinone, etc.; fungicides include Bordeaux liquid, DT, carbendazim, carbendazim, chlorothalonil, methyl thiophanate, zinc, ethyl phosphine aluminum, metalaxyl, trisodium phosphate and so on.
