The root rot of capsicum is usually limited to the root and stem base. Plants are stunted and shorter. The diseased plants in the later stages are wilted during the day and can be restored in the early morning to the early morning of the next day. After repeated days, the plants die. In the early spring and early summer, the rainy weather, high temperature, high humidity, and warm and cool nights favor the onset of disease. Water in the planting fields is low, water in the fields is closed, high humidity in the fields, and wounds in the stems and knots are often harmed, or soil fertilizers that have not been adequately decomposed are used. Will increase the condition. Successively, low-lying land and clay land are heavy. 1 Agricultural measures are suitable for planting early-maturing varieties. The application of adequately decomposed organic fertilizers and the use of formula fertilization techniques can reduce the incidence of disease. 3 to 5 year rotation with leguminous and gramineous crops. Disease-free seeds were used to collect seeds from disease-free fruits. Prior to colonization, the roots of the pepper were soaked with 10 mg/L ABT4 rooting powder solution and then colonized. After planting, the temperature was controlled at 20-30°C, the ground temperature was 25°C, and the humidity was not higher than 90%. Make seedlings thrive. Take ridge cultivation. Avoid flood irrigation, timely drainage after the rain, to prevent the accumulation of water in the field. Irrigation and timely cultivating tillage after rain, enhance soil permeability, promote root wound healing and root development. 2 In the early stage of the disease prevention, spraying or watering 50% thiophanate-methyl-sulfur suspoemulsion 800 times, or 50% root rot WP 800 times, or 50% sterilizing water-soluble 1000 times, or 50 times % carbendazim WP 500 times, or 50% dexfen wettable powder 800 times, or 50% thiophanate-methyl wettable powder 500 times, or 10% double-effect water repellent 200 to 300 times , Or 75% of dexamethasone WP 800 times, or 40% of thioanisole suspension 500 times, 50 liters per 667 square meters of spray liquid, once every 10 days, 2 or 3 times in a row. The drug was stopped 3 days before fruit picking. Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
