花生白绢病是土传性真菌病害,花生苗期即可染病,多在荚果膨大期至成熟期才表现出明显症状,严重发病后用药防治效果较差。另外,目前生产上使用的花生品种普遍对白绢病抗性差,难以通过选用抗病性强的品种来控制病害发生。合理轮作,特别是水旱轮作有利于减轻病害发生。花生播种前后用药进行种子处理或土壤处理,有一定的防治效果。种子处理可以选用戊唑醇及其与多菌灵的混配剂等药,土壤处理可以选用五氯硝基苯等药。在花生发病前或病害发生初期,可以选用异菌脲、菌核净、噻呋酰胺以及戊唑醇、丙环唑及其与多菌灵、甲基硫菌灵 Peanut Sclerotium is a soil-borne fungal disease, peanut can be infected at seedling stage, and more in the pod enlargement period to maturity showed significant symptoms, after the onset of serious drug control effect is poor. In addition, the peanut varieties currently used in production generally have poor resistance to Sclerotium, and it is difficult to control the occurrence of diseases by selecting varieties with high disease resistance. Reasonable rotation, especially the rotation of flood and drought is conducive to reducing the occurrence of diseases. Peanut before and after sowing seed treatment or soil treatment, there is a certain control effect. Seed treatment can choose tebuconazole and its mixture with carbendazim and other drugs, soil treatment can choose pentachloronitrobenzene and other drugs. Before the onset of peanuts or disease early, you can choose iprodione, sclerotimine, thifluzamide and tebuconazole, propiconazole and its carbendazim, thiophanate-methyl
