Abstract：In order to solve the disease problem in the process of potato planting,this paper takes No.3 potatoes as experimental material and adopted new drugs(19.0% pyraclostrobin·dimethomorph water dispersible) for prevention and treatment of potato early blight and potato late blight.The results showed that new drugs were effective in the prevention and treatment of potato early blight and potato late blight and they were suitable for application to the field.When the concentration of new drugs was 400g/hm2,its effect was the best,while the effect in the prevention of potato early blight was 88.80%,and the yield increase was 79.85%,while the effect in the prevention of potato late blight was 89.35%,and the yield increase was 69.70%.
