Because the disease symptoms of the current crops are not very typical, there are even more mixed pests and diseases. Therefore, there may be multiple possibilities for eggplant graying, such as gray mold, plague, brown streak, brown spot, etc., which will have gray lesions. The disease of eggplant occurs more frequently, and it is easy to be infected during flowering period. Therefore, prevention is the main method. In the early flowering stage of eggplant, it is recommended to spray with 50% xanthophyll 800 times + 40% pyrimethanil or 50% procymidone 1000 times, once every 7 days, for 34 times in a row. When pyrimethanil is added to prevent disease. For diseased fruit branches, timely removal of diseased leaves and fruits, throwing away from the plot, and adding organic fertilizer, phosphorus and potassium fertilizer, and controlling nitrogen application can reduce the occurrence of diseases. In addition, Hummer and Red Spider are more serious recently, paying attention to prevention and treatment.
