Eggplant, tomato, pepper, cucumber, soybean and other legume crops are easy to weaken. The biggest problem of preventing diseases with sclerotia in vegetables is that it is easy to be harmed by drugs. After spraying drugs, the leaves change color and even wither. Some leaves turn white while others turn dark brown. Eggplant, tomato, pepper, cucumber, soybean and other beans are easy to form weak vegetables. Taking medicine will not only change the color of branches and leaves, but also seriously affect the yield and quality. This medicine requires low concentration, and its efficacy is greatly reduced at low concentration, so its efficacy is poor. Therefore, vegetable farmers feel that it is useless to spend less and spend more, risking their lives. The solution is to use fumigation instead of spraying. Fumigation can be used in the shed without causing weakness. The method is to use 200 grams of 40% sclerotium wet powder per mu. After closing the warehouse at night, light firewood or corncob first, transfer the remaining fire to the warehouse after smoking, and sprinkle wet powder of sclerotium for smoking treatment.
