Under the condition of field, through the use of chlorothalonil, difenoconazole, and kresoxim-methyl in the perennial three-year peanut seedling, the initial flowering and full bloom flowering in different combinations of spraying treatment to explore three kinds of pesticides even peanut Effect of Leaf Spot Control and Yield. The results showed that the spraying agent treatment zone had some control effects and increased yield on leaf spot disease.
