As the greenhouse cucumber area increases year by year, the disease has become the main obstacle to the cucumber yield and quality. The main diseases of cucumber in the overwintering greenhouse are cucumber downy mildew, blight, powdery mildew and gray mold. In the prevention and control should be based on the use of disease-resistant varieties and nurturing disease-free seedlings, combined with chemical pesticide control, scientific prevention and control to achieve the purpose of increasing production and income. 1. Use resistant varieties. There is a big difference in maturity, yield and disease resistance among varieties. In order to achieve high yield and good quality, we should choose varieties with good disease resistance and resistance, low sittage of melon, good precocity and good commodity, Such as Lu Cucumber 10, Jin Chun 3, Jin You 3 and so on. 2. Pharmacy treatment. Before sowing seeds available 55 ℃ temperature
