The stalk and petiole were immersed brown soft rot. Second, prevention and control measures 1. Select species of species. The disease-resistant, coated seeds are selected and the uncoated seeds are sterilized with a seed dressing or a seed soaking agent. When soaking, soak it in warm water of 55°C for 15 minutes to strengthen the ventilation and disperse moisture. Greenhouses can be cultivated during the summer period, the sheds are filled with water, covered with plastic film, and sterilized by high temperature. If the dead trees or nematodes are serious, the soil (lime nitrogen) is thrown deep into the soil. 2. Reasonably dense planting.

Remove diseased fruits. After the fruiting saplings of the young squash should be removed in time, the diseased fruit should be promptly removed and then buried or burned. When the flowers, stems, and petioles of the squash were affected, the residual flowers were removed in time, and a 1:50-fold killable paste was applied to the diseased parts. The results were good. 5. Chemical control. After sowing, the soil was covered with pesticide, sprayed with insecticides before transplanting, and 863 fungus was applied at the time of colonization to prevent disease and raise roots. Before and during the disease, 72% Jinnuo Duomei WP 600 times, 25.5% Bu Yijia suspension agent 1000 times or 77% WP can be used to control the spray.
