In recent years, Sclerotinia has risen as a major disease affecting rapeseed production. However, during the early stage of rapeseed growth, farmers often neglected the prevention of sclerotinia and caused loss of production. Therefore, we should start with basic integrated prevention and control and prevent it as soon as possible. In addition to the selection of disease-resistant and disease-resistant varieties, comprehensive agricultural measures must be comprehensively applied. The first is to implement flooded and dry crop rotation in Daejeon, which is susceptible to perennial diseases. The second is to apply nitrogen compound fertilizer for the application of ternary compound fertilizers. The third is to improve the facilities of rapeseed water plants in the field. The key is to do rain and dry fields. The fourth is to rationally configure density. Fifthly, at any time during the initial stage of disease, the old leaves of the basal sensation are removed at any time 2 to 3 times. Through these measures, the disease can be effectively reduced. At the same time, we must promptly carry out chemical prevention The focus of prevention and control should be better growing, shading larger rapeseed base and field soil. In the early flowering period, one can spray 8 billion units of Bacillus licheniformis 800 times, two can spray 72% of Streptomycin Sulfate WP 2000 times, and the third can use the same type of Bordeaux solution to spray 100 pounds per acre. Four can use 40% gray nuclear 100 grams of water 100 kg sprayed. When the main stem of the rape blossoms 95~100%, use 40% sclerotia net 75~100g or 25% tebuconazole WP wet powder 60~70g watered 100 kg spray, or use 70% thiol Bujin WP can be sprayed 500 to 800 times.
