Fruit and vegetable disease prevention and control method
Fruit and vegetables that are affected by the disease, the plants grow weak, the fruits lose their commodity value, and the whole plant is seriously dead. The disease can damage seedlings, leaves, stems, and melons on melons. After stems and leaves become infected, the water stains appear dark green patches at the beginning, and the diseased parts are rotted grayish brown or dark brown. When the humidity is high, sparsely powdery white molds appear on the surface; the fruit is affected, mostly from the fruit pedicle, and it is dark green at the beginning. Small spot stains on the spot, after the lesion expands and sag, the flesh soft rot, a white powdery mold layer appears on the fruit surface. The disease can damage leaves, stems, and fruits on peppers. Diseases at the seedling stage mostly occurred at the base of the stems, and the diseased seedlings showed plague-like or litter-like deaths. In the adult stage, the leaves became infected and black-brown plaster-like lesions appeared. The boundary between the diseased part and the healthy part was not obvious. The stems became infected, and most of them started from the nodules and showed brown rot in the wet rot, resulting in the death of the branches and leaves (also called stem branch disease). The fruit is affected, mostly from the pedicle, showing dark green rot or soft rot. The disease can occur during the entire growth period of peppers. Control methods: On the basis of good water and fertilizer management, strengthen disease prevention work. In the pre-disease or early stage, use long-acting, high-quality protective agents to prevent, such as the use of DuPont Meng kill 600 times liquid spray; when the disease occurs, must use special effects, long-acting agents to resist the continued germs Infection. DuPont's fast-acting net is a new generation of pharmaceuticals with fast sterilization and long-lasting drug efficacy. The use method is 2,000 times higher than water, and it is sprayed 2 to 3 times during the disease occurrence period, each time for 5 days.
