Sclerotinia is rape susceptible to spring disease, damage rape stems, causing plants to wither early, has a great impact on yield and quality. Prevention and control should grasp the following measures. First, clear ditch row stains. In spring, there are more rainwater, rape fields are vulnerable to waterlogging, and the respiration and absorption capacity of rapeseed roots are affected at least, and the bad stems of rapeseed roots are affected, which affects the yield. Due to the high humidity, Sclerotinia sclerotiorum is prone to reproduction. Therefore, it is particularly important to clear the trenches in spring. Second, cultivating loose soil. According to the characteristics that the sclerotium is not easy to germinate when it is buried in soil at a height of 10 cm, cultivating tillage 2 or 3 times before rape blossoms can not only control the growth of weeds but also bury sclerotia, can effectively reduce the occurrence of diseases, and at the same time improve the soil. The permeability performance. Third, timely hit the leaves. After the occurrence of Sclerotinia sclerotiorum, the old leaf is most likely to be transmitted to the stems. The old leaves of the base of rape must be stripped in the early stage. Especially during the flowering stage, the old leaves in the middle and lower parts should be stripped in time to reduce the incidence of disease and improve the field. Ventilation and light transmission, reduce germ propagation. The old leaves should be dried after sunny dew, and the old leaves laid should be taken out of the fields for manure. Fourth, increase potassium fertilizer. Potassium fertilization in rapeseed in the spring can enhance the disease resistance ability of rapeseed, and it is generally conducted from late February to early March. Potassium chloride 5 kg to 6 kg per 667 square meters is used, and the roots of water canola are poured on sunny afternoons. Fifth, pharmaceutical control. The focus of pesticide control is continuous cropping plots, low waterlogging paddy fields, and partial overexploitation of nitrogenous fertilizers. Generally, it is used when the diseased leaf rate reaches 8% to 10% in the early flowering period to full flowering period, and 40% for every 667 square meters. Carbendazim glue suspension 100 grams, or 40% of the sclerotium net wettable powder 150 grams, or 50% of fast-inking wettable powder 50 grams, 50 to 75 kilograms of water after spraying 1 to 2 times. Spraying should be sprayed on the stems and leaves in the lower part of rapeseed in order to improve the control effect.
