What are the common pests and diseases in the cultivation of green peppers in peacetime? Green pepper is an annual or perennial herb, and the newly cultivated varieties are red, yellow, purple and other colors. The following is an expert analysis and research on the cultivation techniques and pest control of green pepper, and puts forward suggestions and effective measures to Ensure high yield and stable yield of green pepper cultivation. 1 Main types of pests and diseases 1.1 The main diseases are: viral diseases, epidemics, anthrax, scab, bacterial leaf disease, root rot and physiological diseases. 1.2 The main pests are: sassafras, aphids, whitefly, tobacco budworms, and snails. 2 Pollution-free comprehensive prevention and control technology Adhere to the "prevention of prevention, comprehensive prevention and control", giving priority to the use of agriculture, physics, cattle control, and scientific and rational chemical control. 2.1 Rotation and soil disinfection. Green pepper continuous crops increase the occurrence of various diseases, and can be used for 2 to 3 years with non-solanaceae vegetables. Protected cultivation can deepen the soil by more than 30 cm in high temperature in summer, and then cover the mulch and continue to expose for 10 to 15 days. The seedbed can be mixed with 50% carbendazim, 50~80g per cubic meter of bed soil, and the soil disinfection can be 50% carbendazim or 75% jiato 1kg per 667 square meters. Mix the fine soil and then turn the ground. It is also possible to spray the surface of the wetland with 200 times of formalin for 1 week, and sow or colonize after 2 weeks of air release. 2.2 Varieties Choose varieties that are resistant to and resistant to green pepper virus. 2.3 Cultivate disease-free and strong seedlings. (1) Seed treatment. Soak seeds in warm water at 55 °C for 10~15 minutes. Be careful to keep stirring. When the water temperature drops to 30 °C, stop stirring and then soak for 4 hours to prevent fungal diseases: soak seeds in 10% trisodium phosphate solution at room temperature for 20 minutes. After washing, the seeds can be sterilized by immersion and germination to prevent viral diseases: soaking seeds with 50% carbendazim 500 times for 2 hours, or 50% carbendazim WP or 50% thiram WP for 0.4% of seeds. Species, or 25% metformin WP, seeded with 0.3% of the seed amount to prevent fungal diseases. (2) Spring and summer or summer and autumn seedlings cover the insect net, prevent mites and white powder mites, and prevent viral diseases. (3) Sowing at the right time, cultivating strong seedlings, controlling the temperature and humidity of the seedbed, the temperature during the daytime does not exceed 30 °C, and the temperature is not lower than 15 °C at night, pay attention to the ventilation and dehumidification of the seedbed, timely seedlings, and find the diseased plants, immediately remove them, bring out the seedling bed depth Buried, and treated the diseased hole. 2.4 Implement scientific field management. (1) The sorghum cultivation is carried out in the protected area, and the mulch film is covered, and micro-drip irrigation or sub-film submerged irrigation technology is applied. The protection ground facilities adopt no drip film, strengthen the indoor temperature and humidity control of the shed, timely ventilation, properly control the watering, avoid watering in rainy days, timely drain the water after watering, try to prevent leaf surface condensation, to control the occurrence of diseases. (2) Timely pruning and wiping, timely removal of diseased leaves, diseased flowers, diseased fruits, removal of old leaves that have lost function in the lower part, and improvement of ventilation and light transmission conditions. After pulling the cockroach, remove the sick body in time, and pay attention to the operation of the farmer to prevent the disease. (3) In the facility, the wind will be released at night in the morning, so that the temperature of the chamber will increase rapidly. When the temperature rises to 30 °C, the air will start to release; when the temperature drops to 20 °C, the vent will be closed to delay the temperature drop; the minimum temperature at night will remain at 12~15°C to prevent gray mold. 2.5 Biological control (1) A yellow plate can be set in the protected area to trap white-spotted mites, mites, and scorpion flies, which are yellow-trending pests; (2) Use 2% gram gram (Ningnanmycin) 200~250 times solution to prevent and treat viral diseases in the early stage of the disease: use 1% agricultural anti-wuyinmycin 150~200 times solution to prevent gray mold in the early stage of the disease. (3) Using 0.9% worms 4000 times solution to control spotted fly, cabbage caterpillar, etc., or using 10% Liuyangmycin emulsifiable concentrate 1000~1500 times solution, 5% card dead emulsifiable concentrate 1000~1500 times solution to prevent scutellaria And Ye Hao. (4) Use 72% agricultural streptomycin 3000~4000 times solution or 25% Qingkuling WP 500 times solution to control bacterial diseases. 2.6 Chemical control Because green pepper belongs to the continuous harvest of vegetable crops, chemical control must be strictly in accordance with the safety interval, concentration, and application methods. To avoid the time of picking and applying medicine, it should be picked first and then applied. Chemical pesticides are strictly prohibited for 7 days before harvesting, and biological agents or natural enemies should be preferred. Try to use different types of pesticides as much as possible to control pests and diseases. (1) Prevention and treatment of epidemics. After planting, it can be sprayed with 80% mancozeb wettable powder 600 times solution for protection, once every 15 days. In the early stage of the disease, 40% Phytophthora WP 250 times solution or 58% metalaxyl Mn-Zn WP 500 times solution, 72% DuPont WP WP solution, 60% Anke Mn-Zn wettability can be sprayed. Powder 1500 times solution, 58% Redolmer WP 800 times solution, etc., interval 7 to 10 days, 2 to 3 times in a row. 45% chlorothalonil can be used in the shed, and 3~4kg per hectare. (2) Prevention and treatment of anthrax. In the early stage of the disease, it can spray 70% thiophanate-methyl WP 600-800 times or 80% mancozeb WP 500 times or 50% anthrax WP 400 times or 1: 1:200 times. Bordeaux mixture. Once every 7~10 days, even spray for 2~3 days. (3) Prevention and control of gray mold. Before transplanting, the seedlings were sprayed with 50% keering WP 1500-2000 times solution or 50% phlegm WP 1500 times solution. In the early stage of the disease, 50% keering WP 1500~2000 times solution or 50% phlegm WP 1500 times solution and 60% anti-mildew 600 times solution can be used. 50% methyl thiophanate WP 1000 times solution, 28% gray mold WP WP 500~600 times solution, 65% methicillin WP 800 times solution spray control. (4) Prevention and treatment of viral diseases. Can be used 1.5% phytopathogenic 1000 times solution, 20% virus A wettable powder 500 times solution, 5% toxic water clearing agent 200 ~ 300 times solution or potassium permanganate 1000 times solution and love more than 5000 times liquid mixed spray control . (5) Prevention and control of aphids and whitefly. It can be controlled by spraying 2.5% of deltamethrin EC 2500 times, 10% Dagong WP 1000 times or killing 4000 times. (6) Leafworm control. It can be sprayed with 73% gram of emulsifiable concentrate 2000~2500 times solution, 12.5% ​​必林3000å€æ¶² or 48% ä¹æ–¯æœ¬ä¹³æ²¹ 600~800 times. The above is the main content of the main pests and diseases of green peppers and comprehensive prevention and control. I hope that it will help the majority of farmers and farmers.
