How to solve the problem of pepper with blight? In the process of planting peppers, the disease that can be seen is blight. Once the pepper is infected with blight, the pepper plants will wither and slowly die. Therefore, the planters should pay more attention to the prevention and control of pepper blight. Xiaobian said that peppers are affected by the control measures of blight. First, the disease factors and characteristics 1. The pathogen of blight is called Fusarium, which can survive for a long time and is resistant to winter and cold, and then spreads through soil, irrigation water, rainwater, etc., and repeatedly invades the root wound of the plant. 2, the bacteria like high temperature, can survive at 20-35 degrees, especially at 26 degrees, the most active in the temperature of the bacteria, once the disease, within 15 days can lead to plant death. 3, the bacteria like to moist. Low sputum water, too much irrigation, if you do not pay attention to drainage, it is easy to create a good environment for the disease. 4. Once the disease occurs, the leaves of the lower part of the pepper plant begin to turn yellow and become wilted, and then slowly fall to the top to spread the disease. In severe cases, the stem cortex and roots will be water-soaked and the vascular bundle will turn brown. Second, pepper wilt disease prevention and control measures 1, selective disinfection Before planting, select the varieties with better disease resistance and soak seeds for disinfection. 2. Controlled wet drainage Pepper grows like warm, hi water, and hi-fertilizer. When the pepper plant suffers from blight, it needs to be timely and cut according to the growth stage of the pepper. When planting and pulling, it is necessary to do drainage measures in advance to ensure that the humidity can be controlled; When watering, avoid flooding with large water to prevent water accumulation. 3. Destroy the diseased plant During or after planting, the diseased plants are discovered and destroyed in time to prevent the disease from continuing to infect. 4, the correct management The base fertilizer is sufficient to ensure the nutritional needs of pepper growth. Strict control of planting density. 5, disease management Once blight occurs, you can use 99% carbendazim 3000-4000 times to spray the roots of the pepper.
