Vegetable pest control techniques

Soil, deep secret agents, rational close planting, ground cover, deep groove Takakuro, or dark micro irrigation and ventilation lower humidity, high temperature and nausea and other measures to reduce pests and diseases shed. 8, grafting roots: control of fusarium wilt, verticillium wilt, bacterial wilt, and nematodes and other soil-borne diseases, but also waterlogging prevention, anti-alkali. Third, the physical control 1, the facilities protection: protection of the facilities at the air vents or windows cast insect nets, plastic film covering the summer, insect nets and shade nets, can be rain, sun,[link widoczny dla zalogowanych], anti-pest invasion. 2, booby-traps: the avoidance of the use of pest control. Black light to trap and kill pests, hang yellow sticky insect trapping board or yellow oil board aphids, whitefly and leaf miner, etc.: sweet and sour liquid trap and kill pests such as moths Division. Fourth, biological pest control technology Songyue Min damage vegetables SOUTHERN Zhao Zhiming 1, insect predators: If Trichogramma control Pieris rapae, Plutella xylostella, Spodoptera litura, vegetables borer, Helicoverpa armigera and other Lepidoptera insects, lacewings to prey aphids , whiteflies, spider mites and a variety of Lepidoptera pests eggs and newly hatched larvae, ladybugs, hover flies, hunting bugs and other predatory insects are natural enemies. 2, microbial control: Bacillus thuringiensis, Beauveria bassiana, Metarhizium anisopliae to control diamondback moth,[link widoczny dla zalogowanych], cabbage caterpillar, insect viruses such as beet armyworm nuclear polyhedrosis virus can prevent bollworm and tobacco budworm, prevention and treatment of red Abamectin , white spiders. 3, biological agents: antibiotics, such as agricultural antibiotic 120 agricultural and multi-antitoxin can prevent damping off, downy mildew,[link widoczny dla zalogowanych], powdery mildew, fusarium wilt, black spot and blight, blight prevention Jinggangmeisu, Sclerotium rolfsii, pattern blight, etc.; streptomycin soft rot and bacterial spot disease prevention and control; botanical pesticides such as azadirachtin, veratryl alcohol solution of alkali reduce diamondback moth, beet armyworm, whitefly, etc., matrine, neem, tobacco alkali and other insects on a variety of vegetables have some preventive effect. 'Five, chemical control is not pollution-free vegetables without using chemical pesticides, use of chemical pesticides is effective means to control vegetable pests and diseases, especially epidemic disease, pest outbreak control measures more effective, the key is scientific and rational drug use, it is necessary to control pest damage, but also reduce pollution, the vegetables in the control of pesticide residues in the allowed range. 1, the correct selection of agents: According to the kinds of pests, pesticide properties, using different fungicides and insecticides to control, so that the right medicine. All use of pesticides must be registered by the Ministry of Agriculture, do not use without obtaining registration and licensing of pesticides does not produce, in particular, counterfeit pesticides. 2, prohibit the use of highly toxic, high pesticide residues: the common pesticides. Highly toxic pesticides and phorate, parathion; highly toxic pesticides such as benzene parathion, monocrotophos, methyl parathion, isocarbophos, methyl parathion, Central, isofenphos methyl, endosulfan, Omethoate and other prohibited use of vegetables. Some pesticides such as dicofol, although acute toxicity is not high, but stable, spray or soil after long-term crop residue and difficult to break down, is one of the important reasons of environmental pollution, but also prohibit the use of vegetables. 3, with non-toxic, no residue or low toxicity, low residual pesticide: �� Select pesticides or chemical and biological agents of biological pesticides, such as BT, Beauveria bassiana, insects, bacteria and so on. �� Select specific insect growth regulator pesticides. Such as: diflubenzuron, diflubenzuron and so on. �� Select efficiency and low toxicity pesticide residues. �� pests and diseases in the disaster will cause devastating losses, the only choice for the moderate toxicity and efficacy of pesticide residue, such as dichlorvos, dimethoate, speed kill the small enemy Nixon and so on. 4, control spraying time: According to the occurrence of pests and diseases, find the weak links, timely spraying, can have a multiplier effect. 5, spraying the weather: sunny generally carried out in the absence of wind, the temperature on the efficacy but also to a certain extent. Therefore, according to weather conditions, flexible use of pesticides. 6, strict compliance with guidelines for safe use of pesticides: �� interval of strict control: the safety of all pesticides of different intervals, usually 7 days in summer and winter for 10 days. �� in strict accordance with the provisions of pesticide application: the scope of compliance with pesticide use,[link widoczny dla zalogowanych], control objects, dosage, drug limit inferior, and may not blind to change. �� operating procedures to comply with the safety of pesticides: Pesticides should be stored in a safe place, dispensing body protection must operate to prohibit smoking, drinking, eating, not hand Cazui, face, eyes, and generally not every day application time more than 6 hours, such as adverse reactions should be immediately stripped of contaminated clothing shoes and hats gloves, rinse, scrub your hands, face and other exposed parts of the skin, promptly sent to hospital for treatment.
