The main diseases of green pepper are: seedling disease (sickness disease, blight), viral disease, anthracnose and scab (bacterial perforation); insect pests mainly include aphids, cotton bollworms, and tobacco budworms.
1. Prevention and control of seedling diseases (1) Spread 70% of the original Agki's original powder 25-30 kg per acre before turning the ground.
(2) 50% carbendazim emulsifiable concentrate per square meter of seedbed soil is sprayed evenly at 1:1000.
(3) 2-3 weeks before sowing, 40 ml of formalin plus water 2-4 kg per square meter of bed soil, poured on the bed soil, and then soiled after two weeks.
(4) If there are a few rickets and blights in the seedling stage, they can be timely prepared with 70% nitrochlorobenzene, 5 g of dry soil and 15-17 kg of dry soil, and sprinkled into the roots and shoots.
2, prevention and control of aphids (1) at the beginning of the seedling period with the use of drugs, especially in early June after planting, focus on prevention and control.
(2) Selection of the agent: 40% omethoate emulsifiable concentrate 1000 times liquid spray; 50% malathion 1000-1800 times liquid spray, spray evenly every 7-10 days to improve the control effect.
3. Prevention and control of cotton bollworm and tobacco budworm. In early June and early July, the 1-2 generation larvae occur, and 80% of the trichlorfon original powder can be diluted with water to prevent 1000 times spray control.
4. Prevention and treatment of viral diseases. After planting, before the bud, the mites are sprayed with 5%-15% zinc sulfate once every 7-10 days.
5, bacterial spot disease and anthrax prevention (1) 75% chlorothalonil WP 600 times liquid spray;
(2) 50% anthrax Fumex wettable powder 300-400 times liquid spray;
(3) 200 ppm spray of agricultural streptomycin or neomycin. Generally, even if you spray 2-3 times, you can get better results.
