Eggplant Mushroom Disease is one of the most important diseases on eggplant. It occurred from April to June in various parts of Fujian Province. It generally lost 20-45% and weighed 100%, causing huge economic losses to vegetable farmers in our province. Prevention and treatment of the disease should be based on the scientific selection of disease-resistant varieties, do a good job in the pastoral cleaning, implement a reasonable rotation, scientific fitness cultivation, immediately remove diseased plants and spray protection at the beginning of the disease, and now provide comprehensive prevention and control measures. reference).
1. The resistance of disease resistant varieties to the disease is very different from that of the disease resistant varieties. The cultivation can be done on the surface of the plant. Varieties such as "Nazi vine eggplant or purée eggplant" and other late-maturing varieties, conventional varieties remain in the second pods of eggplant branches, mastered in the eggplant plant height above 25cm, to reduce the germ invasion, to prevent seed fungus.
2. Before cleaning the pastoral eggplant, pepper, tomato, potato, etc., it is necessary to remove the residues of the vegetable garden, clean the countryside, and plow the land; during the growing season, the diseased branches, diseased leaves, and diseased fruits must be brought out of the vegetable garden to be burned.
3. Implement rotations to make reasonable arrangements for cornices and avoid continuous or adjacent planting of solanaceous and cucurbitaceae vegetables, implement a three-year rotation system, and promote ridge cultivation or planting on slopes.
4. With meticulous selection, the scientific fitness cultivation will be based on high-lying, well-drained and sandy loam soils, and the use of deep trenches and sorghum for fine soil preparation. According to different species, it will be planted scientifically and densely. For example, the local “Daizi eggplant†will grow 1300-1400 plants per 667m2. , Reduce the humidity in the field, reduce pathogenic bacteria infestation; Apply sufficient basic fertilizer, increase phosphorus and potassium fertilizers, apply fertilizer in a timely manner, apply scientific fertilization to enhance plant disease resistance; timely drainage in rainy days, no water in the field, reduce field humidity; remove diseased leaves in time, Diseases, and the sick body brought out of the field to prevent re-infection; early season cultivation method, planting in mid-September ahead of August 20th sowing, and strive to start the eggplant fruit in early December that year, to avoid In the rainy season from April to April, rain shelters can be used to prevent rain in April-May, and high-temperature and high-humidity pay attention to pulling up the surrounding film to reduce the occurrence of diseases.
5. Reasonable use of pesticides Eggplant colonization After spraying, use 70% zein zinc wettable powder 500 times solution to spray protection. During the result period, especially before the rainy season, spray the pesticide to prevent the occurrence of diseases; at the beginning of the disease, the diseased plants should be immediately removed and burned and sprayed. According to the test, the agent used 64%?f cream. Manganese zinc (anti-mite) wettable powder or 58% methane manganese zinc wettable powder 500 times or 72% manganese zinc. Cream urea (Kelu) wettable powder 600 Double liquid or 69% manganese zinc. Acryloyl (ank manganese) powder powder 800 times spray, the effect is good, 7-10 days to prevent once, depending on the disease prevention 3-4 times, focus on spraying fruit and leaves, for To prevent drug resistance, use different types of drugs alternately.
