Old vegetable area, nest style, low-lying, Solanaceae vegetables cropping and near the plots of cucumber and tobacco, the incidence of heavier. Generally in the six true leaves of the disease. In recent years, my county is more common, but also the trend of aggravating the spread of a great impact on tomato production. In production practice, we take comprehensive control measures, the strain rate down to 3% or less. The specific approach is: First, the selection of resistant varieties such as Troy Pique, strong abundance, early abundance, early Quebec, good powder 10, 4, 5, 6 and so on. Second, seed treatment before sowing with water soaking 3-4 hours, and then
