Eggplant blight mainly affects the stem base. At the beginning of the disease, brown rots, and produces a white shiny silky mycelium and a yellow-brown rapeseed-like small sclerotia. When severe, the petiole and leaves wither and finally dry off or the whole plant withers.

Appropriate fertilizer application watering before planting full of organic fertilizer. Colonization should use large seedlings, disease-free strong seedlings. After 3 to 4 days after planting, select 1 day of water on a sunny morning, and drain the water in time until the door tomato “blinks” and then start watering and dressing. Before the eggplant enlarges, it needs less water, no water, and water is needed after the door and the eggplant are swollen. Usually with 5 to 6 days of harvesting, pour 1 water (ie, top-dressing water), and then pour water again. The watering must be in the sunny morning, water pouring, and cultivating after pouring to make the soil breathable and conducive to root growth. In the five greenhouses managed according to this method, the incidence rate of eggplant whitefly was below 1%, and the rate of 8 greenhouse disease strains planted by assault was 10% to 20%.

Removal of central diseased plant strains is a signal of disease occurrence. It must be accurately identified, removed early, deep-buried or fired, and mixed with 3 lime or 15% triadimefon wettable powder at a ratio of 1:120 to spread the disease. The soil in and around the hole can be disinfected. For the sick field, 20% methyl-dimethoprim EC can be used 800 times, or 20% triadimefon EC 2000 times, and every 667 square meters can be added to the agricultural use streptomycin sulfate 4 gram. 15% 4ml of Hymex Agent is sprayed on the ground, irrigated or applied 1 or 2 times, once every 15 to 20 days.

Strengthening cultivation, management, and cultivation and management are closely related to disease occurrence. According to the size of seedlings were planted separately. Select sunny morning hot soil transplanting, watering the transplanting seedlings in advance so that the soil blocks into groups, regardless of roots. The site preparation should be detailed, the soil should be straight, organic fertilizer should be put into place, and the air should be ventilated and exchanged in a timely manner. The planting hole is sealed with fine soil, exposing the bitterness and late cover, increasing the lighting time, and the rainy days are required to expose and scatter light. Using these management techniques can promote good plant growth and increase resistance to disease.
