With the improvement of society and the continuous improvement of people's material life, these should be attributed to the country's vigorous implementation of the "vegetable basket" and "rice bag" projects. The greatness of material life has made people pay attention to spiritual enjoyment and pay more attention to their own health. At this time, the continuous emergence of environmental pollution, pesticide residues and excessive fertilizer application have become the most talked about topics on the table. The Ministry of Agriculture has launched the “Non-pollution Food Action Planâ€, and the following pesticide network will take you to learn about “how to use green fruits to select pesticidesâ€.
The use of pesticides in the production of green fruits must comply with the provisions of the Principles for the Use of Pesticides for the Production of Green Foods. Completely stop the use of highly toxic, highly toxic, high-residue or carcinogenic, teratogenic, mutagenic pesticides; stop the use of nationally prescribed pesticides to stop production, sale and use; restrict the use of all-killing and can cause high resistance to pests Pesticide; majestic control of the use of various genetically engineered microbial preparations and hormonal agents.
Stopping the use of pesticides 1, illegal pesticides without pesticide registration certificates, and the “Pesticide Management Regulations†(promulgated on May 8, 1997) stipulates: “No unit or individual may produce pesticide production licenses or pesticide production. Pesticides in favor of documents. No unit or individual may produce, operate, import or use pesticides that have not obtained a pesticide registration certificate or a temporary registration certificate for pesticides."
2. The chemical pesticides used by the state to stop the use of pesticides in the production of green foods, the pesticides used in the suppression of fruit trees are calcium arsenate, lead arsenate, zinc methyl arsenate and ammonium methyl arsenate (Tian An). , ç¦ç¾Žç”²èƒ‚, ç¦ç¾Žèƒ‚, triphenyltin acetate (tuber tin), diphenyltin chloride, toxic tin, chlorinated ethylmercury (Xilisheng), phenylmercuric acetate (赛力散), Calcium fluoride, sodium fluoride, sodium fluoroacetate, fluoroacetamide, sodium fluoroaluminate, sodium fluorosilicate, DDT, hexachlorocyclohexane, lindane, aldrin, dieldrin, dicofol, dibromoethane, two Bromochloropropane, phorate, acesulfate, monocrotophos, parathion, methyl parathion, methamidophos, strontium phosphate, methyl isophosphorus, omethoate, phosphonium, rice bran , different rice glutinous rice, carbofuran, aldicarb, methomyl, insecticidal cockroach, pentachloronitrobenzene, rice sterol, herbicidal ether, oxalic acid ether and organic synthetic plant growth regulator.
3. The pesticides that the state no longer approves for registration In addition to the pesticides used to stop the use listed above, in 1997 China also restricted the production and use of some pesticides. The pesticides that are no longer subject to the approval registration procedures include organophosphorus pesticides such as dimethoate, trichlorfon, phoxim, bromopropylphosphonium, malathion, chlorpyrifos, methomyl, etc. Killing chlorpyrifos and other pyrethroid pesticides; fungicides such as mancozeb, thiram, fumei, anthrax, ethylphosphorus, etc.; herbicides such as sodium chlorate, glyphosate, butachlor, Metformin, quinclorac, etc.; fumigant has aluminum phosphide, chloropicrin, o-methane, etc.; hormone drugs help melanin, ethephon, gibberellin, paclobutrazol and so on.
The pesticides advocated for use 1. The advantages of mineral-derived pesticides and mineral-derived pesticides are long-term efficacy, safe for crops, humans, animals, birds and bees, no obvious pollution to fruits, convenient and economical and efficient. Stone sulphur and Bordeaux mixture are the most used and most effective in fruit tree production.
2. Plant-derived pesticides There are many varieties of plant-derived pesticides. The production has been used with pyrethrin, rotenone, artemisinin, nicotine, allicin, tartary buckwheat, glycosides, sesamin, rot, and natural plant protection agents. (Pepper, star anise, fennel), etc. These agents are characterized by long-lasting sterilization and insecticidal effects, do not pollute the environment and crops, and are safe for humans, animals, birds, bees, and resistant to pests and germs.
3. Biological pesticides
In recent years, biological pesticides have been widely used in fruit tree production. The commonly used biological fungicides are polymycin, veramycin, jinggangmycin, agricultural anti-120, huaguangmycin, liuyangmycin, and bactericidal acid; Commonly used biological killings, acaricides such as wind thunder, Qiqisu, Abadin, Aifuding, Aweibo clear milk, etc.; commonly used biological insecticides are artemisinin, Bacillus subtilis (bt) , insect bacillus, nuclear multi-virus, etc.
4, insect growth regulator is the most representative, the most widely used, the most effective insect growth regulator to kill jujube pesticides. These pesticides have long potency, do not harm natural enemies, do not pollute the environment, and are safe for humans, animals, birds and bees. They are the best choice for green food production and are known as the world's fourth-generation pollution-free pesticides.
5. High-efficiency and low-residue selective pesticides Because of the long-term and large-scale use of highly toxic organophosphorus pesticides and whole-killing pyrethroid pesticides, high-resistance is caused by small insects such as cockroaches, creepers, cockroaches, silkworms and thrips. It is getting harder to control. In the case that the above-mentioned pollution-free chemicals are difficult to be fully utilized in the short term, it is necessary to select some high-efficiency and low-residue special-killing pesticides to replace the traditional drugs. For example, the use of ramie (imidacloprid) instead of dimethoate and omethoate is effective in controlling most of the resistant aphids, locusts, hibiscus, silkworms, thrips, and moths. .
