Bitter gourd Wilt is a fungal disease that occurs in the stem branch of the main vine, and symptoms of water scalding occur at the beginning of infection, and the disease department quickly expands up and down the internodes. Later, the diseased part turned brown and rotted and contracted. The disease can also occur in the ground roots. It also appears as a hot water symptom at the beginning of infection, followed by browning and rotting of the diseased part, and the plants in the shoot lose water and wither. If it is not controlled in time, bitter gourd will cause serious reduction in production. The following describes the prevention and treatment of bitter gourd blight:
First, cultivation and prevention
1. Select resistant varieties. 2. Soil treatment. During the preparation, the soil was exposed for 5 days to 7 days and the soil was fully weathered and whitened. Lime 50 kg -75 kg per acre, neutralize the acidity of the soil and inhibit the growth of germs. 3. Gaochun pit. It is prone to blight with high temperature and humidity. The sorghum deep-hole planting method is used to reduce the groundwater level, prevent water accumulation after the rain, and ventilate the surface soil, which can reduce the disease. 4. Cut the leaves. When the disease begins to occur, the base leaves are sparsely sheared to allow ventilation and dehumidification of field plants and leaves. This can inhibit the development and spread of germs and reduce disease occurrence.
Second, chemical control
When the disease begins to occur, the diseased plant is quickly removed and sprayed with 75% chlorothalonil 500-800 times, or 50% carbendazim 500-600 times, or 70% enemy powder 500 times. 800 times liquid, spray once every 7 days -10 days, 3 times - 4 times. Each time the liquid is sprayed on the stem of the lower part of the plant, spraying to the leaves to the degree of wet not dripping, can receive better results.
