Eggplant Mushroom disease caused by the rot of fruit pieces, is one of the important diseases of eggplant, commonly occurs in various places, eggplant can be affected during each growth period. The general loss is 20% to 30%, and when it is severe, it is more than 50%. The result is also a period of prosperous period, and rainy areas and years are often outbreaks. First, the symptoms of M. blight mainly damage the fruit, but also harm stems, leaves, flowers. In the early stage of disease, the fruit surface is a water-stained round lesion, which is slightly sunken, yellow-brown or dark brown, and develops rapidly under appropriate conditions, gradually causing the entire fruit surface to rot. In conditions of high humidity, the diseased part produces dense white cotton floc, dark brown flesh, rot, disease easily detached, or shrinkage becomes stale fruit. Can also damage the leaves, stems, flowers, diseased stems form water spots, dark green or purple brown spots, when the humidity is sparse white mold. The seedlings were killed and the base of the stems became watery and necrotic, causing cataplexy. Second, the incidence of disease Eggplant Mushroom disease is a fungal disease. It mainly depends on soil and rain. High temperature and humidity, rain after rain, excessive plant density, poor air and light transmission, low altitude, and high incidence of soil viscidity. III. Comprehensive Prevention and Control For greenhouse eggplants to be sown in August, the following preventive measures may be taken: Selection of resistant (resistant) disease varieties: the general round tomato varieties than the long eggplant varieties than disease resistance, such as ink black eggplant, nine leaf eggplant and so on. In addition, thick-skinned varieties are more disease-resistant than thin-skinned varieties, and early-maturing varieties are more disease-resistant than late-maturing varieties. 2. Seed Disinfection: The seed is disinfected before sowing, such as soaking in warm water at 50°C-55°C for 7-8 minutes, which can greatly reduce the incidence of M. blight. 3. The use of plug seedlings: 288 holes can be used six holes, one seed and one seed, adequate nutrients, developed roots, planting does not hurt the roots or less wounds, enhance the disease resistance and reduce the chance of infection. 4. Implementation of crop rotation: To rationally arrange plots, avoiding tomatoes, peppers and other solanaceae and gourd crops. In general, more than three years of rotation will be implemented. 5. Carefully selected. Attention should be paid to the selection of high-dry, well-drained plots, and the use of deep-ditch sorghum cultivation to facilitate drainage after the rain. Try to avoid the heavy soil and the land that is easy to accumulate after the rain. For exposed eggplants that are in fruit setting period, the following prevention measures can be taken: Film Covering: Covering the ground with black mulch or paving between rows, it can block the spatter propagation of Solanum spores in the soil. Sunlight can also be used for high temperature sterilization and to prevent the growth of weeds. 2. Scientific fertilizer: Apply sufficient fertilizer to farm manure, increase phosphorus and potash fertilizer, apply topdressing fertilizer at appropriate time, and do not collect water with fine water. After pouring rain, water should be poured immediately to resist the infection and enhance plant disease resistance. 3. Fine management: timely pruning, hit the old leaves, to improve ventilation and light conditions in the field, timely removal of diseased leaves, diseased fruit, and bring the sick body out of the field to prevent re-infection. 4. Chemical control: The eggplant bed was sprayed with 50% Kedan Dan wettable powder 500 times before colonization of eggplant. Can also be used 50% of carbendazim wettable powder 5 kg mixed soil 100 kg, scattered into the planting hole. After the seedlings are replenished, the roots of the plants are sprayed with 70% of the dexamethasone WP 500 times or 70% dexamethasone WP 500 times and sprayed once every 7 to 10 days. As soon as the central disease strain has emerged, it should be immediately removed, destroyed and sprayed. During the result period, especially before the rain, spraying protection is required. A 1:1:200-fold Bordeaux mixture is sprayed every 7 days to prevent disease. Immediately after the onset of drug application, the drug can be 75% chlorothalonil 500 to 600 times, 50% thiophanate-methyl WP 800 times, 40% EB aluminum WP 200 times, etc., alternating medication, generally Spray once every 7 to 10 days, and spray 3 to 4 times.
