What do you know about the common pesticides used in pollution-free vegetables?

guidelines for the use of pesticides for AA-grade green food and vegetables

AA-grade green food and vegetables refer to the place of origin where the ecological environment quality meets the requirements and specifications, and no harmful chemical synthetic substances are used in the production process. Production, production and processing, product quality and packaging system inspection according to special production safety operation procedures, inspection of goods that meet special specifications and are evaluated by the competent authorities and approved to apply AA-level green food marks. Under special circumstances in the production process, the following standards should be followed when applying pesticides.

It is allowed to use green plant-derived insecticides, pesticide fungicides, repellents and synergists. Such as pyrethrin, derris root, cigarette water, allicin, melia azedarach, melia toosendan, neem, sesamin, etc. Allow the release of parasitic foraging nemesis small animals, such as Trichogramma, drifting insects, predatory mites, various nemesis search engine spiders and insect pathogenic ciliates. It is allowed to use insect pheromones in insect traps, such as sex attractants or other animal and plant attractants. Mineral oil solvent and edible oil solvent are allowed.

sulfur preparation and copper preparation in mineral source pesticides are allowed to be used. Such as sulfur granules, wettable sulfur and omethoate; Sodium thiosulfate, basic copper sulfate, agricultural streptomycin etc. It is allowed to use live microbial pesticides to a limited extent, such as bacterial preparations, pathogen preparations, virus infection preparations, Bacillus, antagonistic microbial agents, insect pathogenic ciliates, plasmodium, etc.

limited application of agricultural machinery antibiotics, such as kasugamycin, polyoxin (polyoxin), Jinggangmycin, Nongkang 12, etc. is allowed to control bacterial diseases and insect pests, and Liuyang bacteriocin is allowed to control mites. It is strictly forbidden to use organic chemical insecticides, acaricides, pesticide fungicides, herbicides and green plant naphthylacetic acid. It is strictly forbidden to use various preparations of chemical pesticides mixed with microbial pesticides. The pesticide application rules for producing grade A green food vegetables allow the application of green plant-derived pesticides, small animal-derived pesticides and microbial strains-derived pesticides.

sulfur preparation and copper preparation are allowed to be used in mineral pesticides. It is strictly forbidden to use pesticides that are toxic, hazardous chemicals, high residues or have "three causes" (carcinogens, fetal malformations, and genetic mutations). It should be emphasized that illegal pesticides that are used in the production and manufacture of basic vegetables and have been used in small quantities must be prohibited from being used in the production of green food vegetables, such as dicofol, omethoate, carbofuran tablets, methomyl, monocrotophos and methamidophos.

various herbicides and organic green plant naphthylacetic acid, although the reasons for their prohibition are not listed, cannot be used for the production of green food and vegetables. If green food and vegetables are really essential, some chemical pesticides are allowed to be used in the production base to a limited extent. Micro-toxic pesticides and some medium-level toxic and side effects pesticides should be used. However, the dosage, application concentration, application frequency and the observation period from the last spraying can be strictly controlled, and each chemical pesticide is only allowed to be applied once in the growth period of a plant.

application standard of pesticide for pollution-free vegetables

when controlling vegetable diseases, we should consider all the ecosystems such as vegetables and diseases, and implement the strategic policy of "nip in the bud, comprehensive control". Based on the prevention and control of agriculture and animal husbandry, comprehensive utilization of various prevention and control countermeasures will create environmental standards conducive to the generation of unfavorable diseases and the reproduction of various nemesis, maintain the balance and species diversity of agriculture and animal husbandry ecosystem, and reduce the damage caused by various diseases.

reasonable non-chemical control methods such as microorganism, physics and green ecological control should be selected as far as possible. When applying chemical pesticides, efficient and safe chemical pesticides should be selected, and the Standards for Safe Use of Pesticides and Guidelines for Rational Use of Pesticides should be strictly observed, which should not exceed their application scope. The pesticide residues in vegetables should meet the requirements of relevant national quality standards.
