Eggplant Mushroom Disease, also known as rotten eggplant, egg drop, and water rot, is one of the most important diseases of eggplant, and it is common in all parts of the country. After the onset of the disease, it spreads very quickly and often causes the entire fruit to rot and fall off. According to statistics, the rotten fruit rate can reach 30%-40% due to illness, and the weight can reach 50%-60% in severe cases, which seriously affects the eggplant yield.

Blight disease can occur in various parts of the plant, but the incidence of fruit is the heaviest. When the fruit is onset, the lower part is more severe than the middle part and the upper part, and it can be affected regardless of the size of the fruit. At the beginning of the disease, water spots on the fruit surface were spotted, gradually expanded, and finally spread throughout the fruit surface. The disease department is slightly depressed and is yellow-brown to dark brown. At high humidity, the diseased area produces a dense white cotton floe, and the internal pulp turns black and rot. When the lesion expands to half of the fruit surface, it is easy to fall off, but the young fruit does not have to fall or fall. Whether or not the fruit is shed, it will be covered with mildew on the surface of the lesion when wet, and finally shrink into dark brown and brown fruit, which is difficult to pick up. Fruit that has been infested by the bacteria but has not shown symptoms will rot soon after harvesting. When the stems and stems and leaves are infested, the color becomes black and white molds are produced until they die.
Prevention and cure of eggplant Mushroom disease should be mainly to strengthen the cultivation and management, combined with pharmaceutical protection, two-pronged approach, prevention and control.
1. Use resistant varieties.
2. Create environmental conditions conducive to the growth and development of eggplant during cultivation, which are not conducive to bacterial infection, such as cultivation in high ridges, fruit picking in early harvest, timely removal of yellow leaves, and application of organic fertilizers.
3. Implement rotation. It is best to rotate with legumes and vegetables.
4. Before and after or before and after watering, spray once every 5-7 days 80% mancozeb WP 500 times, 75% chlorothalonil wettable powder 600 times, 50% WP wettable powder 400 times liquid or 60% methylaluminium copper wettable powder 500 times liquid and so on. Can also be used 0.1% zinc sulfate + 0.2% potassium dihydrogen phosphate + 0.4% urea + 0.25% cytokinin + 0.3% DT fungicide spray mixture to prevent.
5. The main source of infection of M. blight is the spores of pathogens in the soil. Black or colorless plastic films can be laid on the ground to prevent bacteria in the soil from splashing on the fruits of the eggplant by drip-proof membranes. This measure can also increase the ground temperature, reduce ground water evaporation, and reduce the number of watering.
