According to the consultation and consultation among experts organized by the National Agricultural Technology Center, the late blight of potato in 2015 may be prevalent in the main producing areas in southwest, northwest, north and northeast, with an estimated area of 35 million mu. In order to control such serious diseases as potato late blight, the National Agricultural Technology Center has formulated a scientific control and prevention technology program. I. Prevention and Control Targets The prevention and control disposal rate in the restarting areas reaches 100%, and the prevention and control disposal rate in the areas with frequent occurrences is more than 80%, among which the special prevention and control measures are over 20% and the overall prevention and cure effect is over 80%, and the damage loss rate is controlled at Below 5%. Second, prevention and control strategy (A) the overall prevention and control strategy. The implementation of the promotion of disease-resistant varieties and virus-free seed-based seed potatoes Department
