Eggplant Mushroom Disease is a major disease in the cultivation of eggplant. In the northern region, it occurs in the hot and rainy season of July to August in summer. Once the disease occurs, it spreads very quickly and usually causes large areas of eggplant to rot and fall off. Seriously affect the normal production of summer autumn aubergine eggplant. Therefore, various measures must be taken for comprehensive prevention and control.
1. Symptoms of disease Eggplant M.blight disease mainly affects the fruit, but it also affects the leaves, tender stems and other parts. When the fruit is victimized, the damage to the old fruit near the ground is more serious. At the early stage of disease, the bacteria first invade the surface of the fruit, and the diseased part has a water-stained round yellow-brown lesion and a slight sag, and then the lesion gradually expands and finally spreads to the entire fruit. With the expansion of the lesion, most of the disease will be Falling off and rot, when the humidity is high, a white flocculent mycelium grows on the surface of the lesion, and the internal pulp turns black and rot. The incidence of leaf disease mainly starts from the edge of the leaf blade and the tip of the leaf. The lesions are round water-stained, mostly dark brown with obvious ring patterns. When the weather is wet, the diseased department will grow sparse white mold. The stem was infected. The diseased part was initially stained with water and turned brown and decayed. The branches and leaves above the diseased part were wilting and drooping.
2. The cause of the disease Eggplant Blight is a fungal disease. The pathogenic oocysts can overwinter in the soil with the diseased body. After wintering, the fruits, stems and leaves near the ground are first infected, and then sporangia are generated on the lesions, and the sporangia are then transmitted through wind, rain, and irrigation. The optimum temperature for the growth and development of M. blight is 28 to 30°C, and the relative humidity is required to be above 85%. Therefore, high temperature and high humidity conditions are conducive to the occurrence of diseases. The northern region is in the rainy season from July to August, and the temperature is relatively high, so this period has become the epidemic period of eggplant disease in open field. Especially in the soil with heavy clay, low-lying land, poor drainage, excessive planting density, and poor ventilation and ventilation, the incidence of land is more serious.
3. Control methods
3.1 Agricultural control selection is suitable for local cultivated disease-resistant varieties, according to different varieties to determine a reasonable planting density, general early-maturing varieties should be controlled at 4000/667 square meters, middle-late-maturing varieties controlled at 2500 to 3000/667 square meters; For the crop rotation system of more than one year, it is best to use crops such as legumes or leeks and garlic, and avoid continuous cropping with solanaceae and gourd crops; the selection of cultivation plots is suitable for sandy loam soil with fertile soil and convenient irrigation and drainage. The method of deep ditch and sorghum is used for soil preparation, and the basic fertilizer is mainly applied to mature organic fertilizers. During the cultivation process, some phosphorus and potassium fertilizers are added appropriately, nitrogen fertilizer is reduced, robust plants are cultivated, and disease resistance is improved; timely cultivating, weeding, and Pruning, snoring, timely removal of the lower diseased leaves, diseased fruit, improve ventilation conditions in the field, reduce the source of re-infection; also pay attention to the summer heat period, immediately after noon rain poured cold water, and to exclude the field water Clean, this can reduce the field temperature and humidity, reduce the incidence of disease.
3.2 Before the onset of chemical control, spraying protection should be carried out in time to prevent the occurrence of diseases. Immediately after the onset of drug application control, reduce the harm caused by the disease. Pharmacy can choose 72% of DuPont Kelu wettable powder 800 times liquid; 77% can kill wettable microparticle powder 500 times; 58% metalaxyl manganese zinc 400 ~ 500 times liquid; 69% Anke manganese zinc wettable powder 900 times liquid; 75% chlorothalonil wettable powder 500 to 600 times; 50% thiophanate-methyl WP 800 times; 72.2% Prec fluid 700 to 800 times and so on. Spraying can be based on the condition, spraying once every 7 to 10 days, generally 3 to 4 consecutive medications.
