White feather disease is a common fungal disease on the water chestnuts. When the disease conditions are appropriate, it will cause the entire diamond disk to rot. In an interview with Professor Li Liangjun of the Aquatic Vegetables Research Laboratory of the Yangzhou University, the reporter recently learned that mid-late to mid-August to mid-August is the peak period of white peony disease in the whole year, and production should be detected and prevented in a timely manner. Rhizoctonia solani, also known as Chrysospora sclerotiorum, and Phyllanthus spp., mainly damage the leaves. A small number of water-streaked yellow small lesions occur initially in the middle of the leaves. Afterwards, they increase and expand, and white thick mycelium grows on the leaves and leaves. Gradually, the entire leaflet yellows white and decays, spreading to neighboring leaves, and the entire diamond disk decays. Severe 2 to 3 days can cause discarded discs, resulting in lost. The disease is a fungal disease. The pathogen is small sclerotia of the genus Sclerotium. The mycelia and sclerotia are overwintered on the sick body, soil, and weeds surrounding cultivated fields. Mycelium and sclerotia spread with the water stream and contact with the leaves of the water chestnuts. In the future, the disease will be expanded through contact with diseased plants and propagation of hyphae. According to Li Liangjun, the white peony disease bacterium likes high temperature and high humidity. From July to August, if the temperature is high and the rain is heavy, it is most likely to occur and become popular when rain and hot weather repeatedly appear when it is sunny. After mid-September, as temperatures drop, old yellow leaves will gradually reduce the disease. Contamination of water quality, congested discs, and poorly managed ponds are usually more serious. Lianzhuang Liantang has enough pathogenic bacteria in the field and is more susceptible to disease. To prevent the disease, we should pay attention to reasonable close planting to prevent overcrowding of the water surface in summer and autumn; keep the water quality clean and prevent pollution; at the same time, pay attention to applying organic fertilizer, phosphorus and potash fertilizer, and avoid partial nitrogen fertilizer. In the early stage of disease, the diseased leaf or diseased disc should be removed in time, carried out to destroy or buried, and sprayed with bactericide to prevent and treat it. The agents commonly used for the control of fungal diseases such as thiophanate-methyl, procymidone, carbendazim, chlorothalonil and the like can be used. In addition, according to relevant information, the following measures should be taken to prevent the occurrence of Lingtang, which has occurred more severely perennial. The first is a crop rotation that can be practiced for 2 to 3 years with other aquatic crops. The second is to deal with Lingtang. Drainage and drainage of the convenient pond, in the water chestnuts after the completion of draining water, remove diamond residues and weeds, reduce the source of bacteria. In the second year of February before and after irrigation, keep the deep water layer for more than 60 days to inhibit the germination of sclerotia and salvage the pond residue. One month before the seedlings were drained, the water was dried in the pond for about 10 days. The 50% carbendazim wettable powder 500 times solution was used to sterilize the topsoil and the seedlings in the pond, and then the water was sowed.
