Which pesticides can be applied to vegetables?
Which pesticides can be applied to vegetables? Which pesticides are prohibited from use? With the growing severity of vegetable diseases and insect pests, more and more pesticides are being used on vegetables. Because vegetables are an essential daily food for people, their roots, stems, leaves, flowers, and fruits are used as edible parts, and some can also be eaten raw. If pesticides that cannot be applied to vegetables are used at will, they will cause pollution to the vegetables and cause chronic accumulation of human and animal toxins or acute poisoning. Therefore, quasi-pesticides should be used on vegetables, and products should be marketed after safe intervals.
(1) Pesticides that are banned on vegetables: 1 Very toxic pesticides: such as phosphoamine, methamidophos, monocrotophos, carbofuran, 3911, 1059, 1605, methyl 1605, Suhua 202, chlorpyrifos, isopropyl Phosphorus, trisphorus, zinc phosphide, aluminum phosphide, cyanide, fluoroacetamide, arsenic, chloropicrin, pentachlorophenol, dibromochloropropane, 401, etc. These pesticides are highly toxic to humans and animals and can enter the body through people's mouth, skin and respiratory tract to cause acute poisoning. 2 Highly toxic, long-lived, pesticides that can cause accumulation of poisoning: such as mercury preparations, Saili San, and Xi Lisheng. These pesticides have a long residual effect and have a half-life in soil of 10 to 30 years. They can cause cumulative poisoning in human and livestock nervous systems. 3 Pesticides with low toxicity and long residual effect, which can cause accumulated poisoning: For example, HCH, DDT, chlordane, Toxicene, and Dieldrin have been banned by the central government for a long time. These pesticides are chemically stable, not easily decomposed by the effects of sunlight and microorganisms, and have a small volatility. They can be eliminated in the soil for 10 years by 95%. It is also a fat-soluble drug that can accumulate in plant and human and animal fats. Insecticides can cause chronic poisoning in humans and animals and are banned on vegetables.
(2) Pesticides approved for use on vegetables: 1 Biopesticides. These pesticides are non-toxic to humans and animals, and have no pollution to the environment. They are pollution-free pesticides, such as insecticide-toxin insecticides, 7216 bacteria, and Bacillus thuringiensis; fungicides such as DT. 2 Efficient, low-toxicity, low-residue pesticides such as dichlorvos, trichlorfon, dichlormic acid, dimehypo, phoxim, marathon, fenvalerate, transfluthrin, dicofol, carbaryl, Dimethoate, omethoate, acephate, campestris, fenthion, isoprophos, diazinon, phenazine, permethrin, etc. 3 High-efficiency, low-toxicity, low-residual bactericide pesticides such as Trichoderma, carbendazim, chlorothalonil, beta-aluminum, thiophanate-methyl, thiophanate-methyl, sterilized dan, zesin, dexamethasone, and generations Senmangan, Desenonium, Lithium Sulfur, Bordeaux, Copper Soap, Fumei Shuang, Formamide, Copper Sulphate, Perbosome Net, Potassium Permanganate, Formaldehyde, Sulfur Powder, Manganese Zinc, Triadimefon, Agricultural Resist 120, 83 increase agent and so on. Herbicides: such as trifluralin, herbicidal ether, herbicide No. 1, paraquat, and cable.
