Goldfinger grape is a high-grade grape variety, but its quality is good, but its disease resistance is poor. Especially in greenhouse cultivation, pests and diseases are heavier. In case of low temperature and humidity, poor ventilation and light transmission during flowering, cob brown rot is more likely to occur. . ã€symptom】 The disease mainly harms the cobs and pedicels of grape ears. The cob was initially a light brown water-stained lesion. After expansion, it gradually turned dark brown and slightly sunken. When the humidity was high, the brown mold layer was visible on the spot. If the small branches of the cobs develop, when the lesions are surrounded by 1 week, the buds or young fruit on them will also shrink, dry, and fall off. In severe cases, almost all buds or young fruit fall, seriously affecting the yield of grapes, and the prevention and treatment of this disease cannot be ignored. Incidence conditions The climatic conditions have a greater impact on the disease. Grapes at the young ear and flowering stage are seriously affected by low temperatures and excessive humidity in the shed. Different species have different disease resistance, Eurasian species are susceptible to disease, and European and American hybrids are more resistant to disease. How to control One is to remove dead leaves and rotten leaves in time before the shed, and eliminate pathogens. The second is to cover the film in the greenhouse and reduce the humidity inside the greenhouse. The third is to strengthen soil fertilizer management, increase tree vigor, and increase disease resistance. The proportion of N, P, and K is properly balanced, and attention is paid to the application of trace elements such as calcium, boron, iron, and zinc. The fourth is to pay attention to flowering, do not water, reduce humidity, and timely handling of the secondary tip to solve the problem of air and light transmission. ã€Pharmaceutical Control】 It can spray 8% Ningnanmycin 2000 times at the beginning or early onset of the disease, and spray it once every 7 days. It can also be sprayed with 80% tebuconazole 5000 times solution and 70% thiophanate-methyl 1000 times solution. The above agents can effectively control the harm of the disease as long as they are used at intervals of 7 days and are used alternately.
