Agricultural control (1) Clearing sheds before planting and ploughing the soil to reduce the number of eggs remaining in the front shed. At the early stage of disease, diseased branches and leaves of the diseased plants were promptly removed and brought out of the shed to be destroyed in a centralized manner, which reduced the occurrence of diseases and insect pests. (2) Control the number of watering and the amount of water. At the same time, using good weather, timely ventilation, reduce the humidity within the greenhouse, reduce the incidence. 2, chemical prevention (1) Gray mold: In the early stage of disease, 40% Shijiale 1500 times liquid or 50% procymidone or 50% quickinking wettable powder 1000 times spray is used per acre of tomato. The eggplant uses 50% iprodione (promethine) WP 1000 times spray per acre. If the humidity in the greenhouse is too large, use 45% chlorothalonil or 15% procymidone aerosol 200-250 g per acre, place the smoke evenly in several places, and then close the fumigation room in the evening and open the next morning. (2) Epidemic disease: When a few leaves are found in the middle and lower parts of the tomato, 70% mancozeb 900 times liquid or 40% DuPont Fuxing Emulsion 8000 times spray can be used. (3) Leaf mold: In the early stage of disease, 47% Garethon WP 600 times solution or 58% metalaxyl MnZn wettable powder 500 times solution was used. (4) Liriomyza leaffly, Bemisia tabaci: leaf miner flies with 75% ciprofloxacin WP 3000 times. The powdered aphid was sprayed with 25% pymetrozine wettable powder 24g, or 5% methoquinone salt 15g sprayed on water 30kg. For sensitive plants such as strawberries, yellow traps can be used to ensure crop safety. The above medicaments are controlled once every 7-10 days, and are continuously controlled 2-3 times.
