In recent years, with the continuous expansion of the production area of ​​colored peppers in the summer facilities and the increase of planting years, the occurrence of various pests and diseases has become increasingly serious. According to the different growth periods of colored peppers, the comprehensive control techniques are as follows. 1, seed treatment (1) Select the corresponding commodity coated seeds for different control objects. (2) Prevention and treatment of viral diseases Dry seeds were placed in an oven at 70 ° C for 72 hours or soaked with 10% trisodium phosphate solution for 20 minutes. (3) Control disease, anthracnose and bacterial diseases, soak for 5 minutes with 55% warm water, then put in cold water to cool. 2. Nursery bed and seedling equipment disinfection (1) disinfection of seedbed soil with 30 to 50 ml of formalin per square meter, adding 3 liters of water, spraying the bed soil, sealing the seedbed with plastic film for 5 days, uncovering the film for 15 days, or sowing the bed soil before sowing. After that, spray the seedbed with 72.2% Plex water 400-600 times solution, use 2~4 liters per 667 square meters, or use 5 to 10 grams of gold leidomere per square meter of seedbed soil to prevent blight and blight. And stumbled. (2) Disinfection of the seedling device is sprayed or soaked with 300 times liquid formalin or 0.1% potassium permanganate solution. 3. Prevention and control of main pests and diseases in seedling stage (1) The seedbed is covered with plastic film, insect net, sunshade net, rainproof, mites, whitefly and sunscreen. (2) Half a month after emergence, 1 time 1 leaf and 1 time before transplanting, each time, Dak Ning 600 times liquid or Amishida 1500 times liquid, to prevent fungal diseases, and promote the robust growth of seedlings. (3) Spray the seedlings once with NS-83 enhancer 50 times solution 15 days before planting, and remove the virus disease plants in time. (4) The white powder mites were found in the seedling stage, and the seedlings were sprayed with AKTEC 2500 times. In order to prevent the harm of white mites after transplanting, AK～2500 times before the seedlings were transplanted, 1500～2500 times Spray the roots on the seedbed or nursery nutrient bowl, spray 2 to 3 kg of liquid per square meter of seedbed or 30 ml of each seedling. 4. Planting and pest control in the final stage (1) All vents are sealed with a 20-30 mesh nylon gauze to prevent the intrusion of aphids and whitefly. (2) Confined greenhouse before planting, use 2 to 3 kg of sulfur powder per 667 square meters of shed, add 0.25 kg of 80% dichlorvos, mix with sawdust, pile up and ignite, then close the shed for a day and night, completely eliminate all the shed Insects are replanted after being odorless in the ventilated shed. (3) When transplanting, use Jindudumir 600 times liquid to fill the roots, each irrigation 0.1-0.25 kg, to control the root rot, blight and disease of the pepper after transplanting. (4) Spraying Knin 600 times solution about 15 days after planting to prevent most fungal diseases. 5. Main pest control in the fruiting period (1) Remove the remaining petals in time to prevent the occurrence of gray mold. (2) Continuous application of Amishida 2 to 3 times from the initial stage of flowering to the peak period, with a spraying interval of 15 to 20 days. It prevents most fungal diseases and promotes the growth of flowering peppers and flowering and fruit setting. (3) After spraying 2 to 3 times of Amisida, spray with Dakoning, Shigao and Jinleidumir alternately, spraying once every 10 to 15 days. (4) The aphid and whitefly mites occur in the adult stage, and the Aketai 5000 times solution plus Kungfu 2000 times solution is used for prevention and treatment, and even sprayed twice, spraying once every 3 to 5 days. (5) Helicoverpa armigera and tobacco budworm occur, spray BT emulsion 200 times solution or 1.8% avermectin 5000 times solution or taibao emulsifiable concentrate 2500 times solution. (6) After pruning, apply 10 times milk powder solution or fresh milk solution to the wound to prevent the occurrence of viral diseases. Strictly according to the above application schemes to control pests and diseases, generally no disease, gray mold, powdery mildew, anthracnose and other diseases will occur. In the event of a disease, the appropriate medication should be taken immediately.
