Preservation of special soybean downy mildew for fresh food

Downy mildew generally occurs in the soybean producing areas in China, and occurs in areas with cold and heavy rain during childbirth. The disease is harmful to soybean seedlings, leaves, pods and beans, resulting in plant dwarfing, leaves withered early fall off, and even dead. The 100-seed weight of the damaged soybean was reduced by 4% to 16%, the oil content was reduced by 7.5%, and the protein content was reduced by 1.8%. The increase in imperfect grains, moldy grains, and heterogeneous grains seriously affects the edible and economic value of soybeans. Soybean downy mildew is a fungal disease. Irregular grayish white cream on the surface of the diseased granules is the oospores and hyphae of the bacteria. The cotyledon does not show symptoms. The adult plants have round or irregular pale green and yellow patches. , scattered or connected together, the leaves back with gray mold, soybean meal surface generally no obvious symptoms, peeling open the pods visible pods within the irregular block gray mold-like material. The pathogenic bacteria used oospore to overwinter on the seed and diseased leaf tissue, and mainly used the oospores on the seeds as the source of the first infection. The northern part of the country began to occur in the middle and late June, and July to August was the epidemic period. Rainy and humid years were favorable for the onset of disease. Control methods: 1 Breeding and planting disease-resistant varieties, controlling the occurrence of diseases and the spread of the physiological race of a certain pathogen. 2 Seed treatment, fungal diseases caused by seed bacteria. Before sowing, 3.5% metalaxyl or 50% thiram can be used for seed dressing. 3Cultivation measures: Non-legume crops should be selected for deep turning and rotation, and should not be rotated with the host crop of pathogens; weeds and weeds should be removed to remove the diseased plant residues from the field to reduce the bacteria source, remove water, and increase phosphorus and potassium fertilizers to increase plant growth. Disease resistance. 4 Chemical control, timely use 58% metalaxyl MnZn WP, 72% Kelu wettable powder or 64% antivirus WP in accordance with instructions, spray once every 7-10 days, even spray 2 to 3 times; 75% chlorothalonil WP can also be used 700 ~ 800 times, 50% carbendazim WP and 65% zein zinc WP 500 times spray to control the spread of the disease has a certain effect.
