Does not work with susceptible tomatoes, cucumbers, peppers, and potatoes to block or reduce the source of soil contamination. Tomatoes, cucumbers, and peppers under shed conditions are cultivated in small sorghum to enhance the ventilation management after irrigation, and non-dropping membranes are used to prevent dripping from the membranes, and close-to-plant plants are used to improve air- and light-transmitting conditions between plants and reduce the temperature difference between day and night. Avoid the condensation of leaves and the formation of water film, and increase the application of phosphorus and potassium fertilizer.
All kinds of infected vegetables, found that the central disease should be promptly removed, and the use of 1:1:200 Bordeaux fluid blockade of the disease center.

Cucumber sheds for drug control: 75% chlorothalonil 600x, 50% cetanol 5000x, 64% antiviral M8 WP 500x, 25% trefenrel, and 54% thiram 1 1 mixture of irrigation roots. The potato late blight can be sprayed with 40% EB 200 times solution and 25% metalaxyl stalk and leaves; when mixed with early blight and late blight, 58% metalaxyl MnZn 500 times can be sprayed 2 times. -3 times.
