1, the main diseases of pepper: damping-off, root rot, virus disease, disease, anthrax, bacterial wilt, powdery mildew, bacterial leaf spot and so on. 2. Main pests of pepper: cotton bollworm, tobacco budworm, aphid, red spider and so on. 3, the principle of prevention and control: (1) Adhering to the plant protection policy of "prevention as the mainstay and comprehensive prevention and control", according to comprehensive management of pests (adopting resistant and resistant varieties and pests, focusing on cultivation and control, biological (ecological) control and physical and chemical control A combination of comprehensive prevention and control measures. (2) Agricultural control: Use disease-resistant seed varieties, cultivate disease-free strong seedlings, strengthen cultivation and management, cultivate robust plants, and clean the pastoral area. Reduce the number of insects, implement crop rotation, change crops, use paddy-pepper, bean-pepper, etc., onion-pepper, cucumber-pepper, etc. to change the crops, reduce the intermediate host or initial infusion source, create suitable fertility conditions, and properly handle Waste, reduce the number of pathogenic and insect sources. (3)Scientific fertilization: Balanced fertilization by soil testing, increasing the use of fully decomposed organic fertilizers, composts, manure, biogas fertilizers, crop straws, peat, and cake fertilizers, and promoting application of raw bacterial fertilizers, including humic acid fertilizers and rhizobia Fertilizers, phosphorus bacterial fertilizers, compound microbial fertilizers, etc., and less applied chemical fertilizers to prevent soil salinization. Promote the use of special fertilizers for peppers, and prohibit the use of nitrate nitrogen fertilizers and compound fertilizers produced from nitrate nitrogen fertilizers. (4) Physical control: Insect killing traps are used to trap and kill insect pests using insecticidal lamps in the production base; yellow plates are trapped and killed, and yellow plates are trapped to kill insects such as locusts, leaf miners and other insect pests in Daejeon, a vegetable production base of peppers. The yellow board size is 25-40, suspended 30-40 pieces per mu, when the yellow board is full of insects, then re-coat a layer of oil, once every 6-7 days; use other repellent measures, silver gray film to avoid aphid. The scientific use of dry heat, warm soup seed treatment, with sweet and sour liquid to trap liquid moth pests. (5) Biological control Use biological or metabolic products to control the occurrence of pepper pests and diseases, actively protect and utilize natural enemies, and truly control insects, treat bacteria with bacteria, and treat bacteria with bacteria, such as the use of grasshoppers, seven-marked insects, etc. Prevention and control of hot pepper borer; use of Bacillus thuringiensis to control hot pepper larvae, use of S52 satellite virus to control green pepper virus disease, use of streptomycin sulfate, streptomycin, penicillin potassium chloramphenicol, agricultural anti-120 and other bacteria. Using 0.3% azadirachtin, Liu Taibao and other biological pesticides to control pests. Foliar potassium dihydrogen phosphate can be repelled by cotton bollworm, tobacco budworm spawning: foliar spray Opal organic fertilizer can increase plant resistance, prevent the occurrence of green peppers sooner or later. (6) Chemical prevention and control: scientific and rational application of chemical control techniques, adopting new pesticides with high efficiency, low toxicity, and low residue, suiting the right medicines, and preventing and controlling them at an appropriate time.
