With the advancement of society, people’s material lives have been continuously improved. All these should be attributed to the successive implementation of the “vegetable basket†and “rice bag†projects by the country. The great wealth of material life has made people begin to pay attention to spiritual enjoyment, and at the same time, they are more concerned with their own health. At this time, the ever-present environmental pollution, pesticide residues, and excessive chemical fertilizer application have become the most talked-about topics on people's tables. The Ministry of Agriculture has launched a "pollution-free food action plan". This publication has opened up an expert information desk for the implementation of this action plan. This issue also invites experts in this area to talk about: “How to choose pesticides for green fruitsâ€. The use of pesticides in green fruit production must comply with the "Guidelines for the Use of Pesticides for the Production of Green Food." Full prohibition of the use of highly toxic, highly toxic, high residue or carcinogenic, teratogenic, mutagenic pesticides; prohibit the use of pesticides that the country explicitly prohibits the production, sale and use of; prohibit the use of total killing and can make the pests produce high resistance Pesticides; Strictly control the use of various genetic engineering microbial agents and hormone drugs. Pesticides prohibited from use 1, pesticide-free registration certificates, and production licenses for illegal pesticides The State "Regulations on the Administration of Pesticides" (issued on May 8, 1997) stipulates: "No unit or individual may produce pesticides without production license or pesticide production. The approved pesticide shall not be produced, operated, imported or used by any entity or individual without using a pesticide registration certificate or pesticide temporary registration certificate.†2. The “Pesticide Use Guidelines for the Production of Green Food†stipulated by the State forbidding the use of chemical pesticides. The pesticides that are forbidden to be used in fruit trees are calcium arsenate, lead arsenate, zinc methyl arsenate, ferric ammonium arsenate (Tian'an), Formamide, Formamide, Triphenylacetate tin Diphenyltin chloride, toxin tin, ethyl mercuric chloride (Xisheng), phenylmercuric acetate (Sai ​​Li San), calcium fluoride, sodium fluoride, sodium fluoroacetate, fluoroacetamide, fluoroaluminate Sodium, Sodium Fluorosilicate, DDT, BHC, Lindane, Aldrin, Dieldrin, Dicofol, Dibromoethane, Dibromochloropropane, Phosphor, Tetraphos, Monocrotophos, Parathion , methyl parathion, methamidophos Treatment of Phosphorus, Methylisotriphos, Omethoate, Phosphamine, Indole, Indole, Carbofuran, Aldicarb, Methomyl, Insecticide, Pentachloronitrobenzene, Rice Blast Alcohol, herbicidal ether, herbicidal ether and organic synthetic plant growth regulators. 3. In addition to the banned pesticides listed above, the State no longer approved the registration of pesticides. In 1997, China also imposed restrictions on the production and use of some pesticides. The insecticides that are no longer subject to approval and registration include dimethoate, trichlorfon, phoxim, bromophos-phor, malathion, fenitrothion, methomyl and other organophosphorus pesticides, extermination, and rapid extinction. Kill Pyrethroids and Detoxify Pyrethroid Pesticides; Fungicides include Mancozeb, Fumei Shuang, Fumei, Anthraquinone, Alpha-phosphorus, etc.; Herbicides include Sodium Perchlorate, Glyphosate, Dibutaryan, etc. Dimethyl tetrachlorine, quinclorac, etc.; fumigants are aluminum phosphide, chloropicrin, omega, etc.; hormonal agents can help prime, ethephon, gibberellin, paclobutrazol and so on. Advocates for the use of pesticides 1, mineral sources Pesticide minerals source of pesticides have the advantages of long duration of efficacy, crops and humans, livestock, birds, bees safe, no obvious pollution of the fruit, easy to use, cost-effective. The most used and most effective ones in fruit production are lime sulfur and Bordeaux mixture. 2. Plant-derived pesticides There are many types of plant-origin pesticides, including pyrethrin, rotenone, phthalein, nicotinic acid, allicin, buckwheat, chuanxiongsu, sesamin, chlorhexidine, and natural plant protection agents. (Pepper, star anise, fennel), etc. These pesticides are characterized by stable and long-lasting bactericidal and insecticidal effects. They do not pollute the environment and crops. They are safe for humans, livestock, birds and bees, and are not susceptible to pests and germs. 3. Biological pesticides Biopesticides have been widely used in the production of fruit trees in recent years. The commonly used biocidal agents are polyoxin, kasugamycin, jinggangmycin, agricultural antibiotic 120, huaguangmycin, Liuyangmycin, and bacteria. Toxic, etc.; commonly used biocides, acaricides are wind and thunder, Qi Qi Su, Abantin, Aifuding, A Wei insect clear oil, etc.; commonly used biological insecticides are Artemisinin, Su Yun's Bacillus (bt), insecticidal bacteria, nuclear multi-body viruses, etc. 4, insect growth regulators are the most representative, the most widely used, the most effective insect growth regulator diflubenzuron pesticides. These pesticides have a long duration of efficacy, do not harm natural enemies, do not pollute the environment, and are safe for humans, livestock, birds and bees. They are the best choice for green food production and are regarded as the fourth generation of pollution-free pesticides in the world. 5. Efficient and low-residual selective pesticide Due to the long-term large-scale use of highly toxic organophosphorus pesticides and permethrin pesticides, high resistances to small pests such as cockroaches, creepers, cocoons, leafworms, and thrips are produced. More and more difficult to control. In the case where the above-mentioned non-environmental pesticides are difficult to be fully applied in the short term, it is necessary to select some highly-efficient and low-residue monosultap pesticides instead of traditional ones. For example, the use of acetamiprid (imidacloprid) instead of dimethoate emulsion and omethoate to control most resistant aphids, migratory locusts, hibiscus, leafworm, thrips, leafminer, etc. .
