Symptoms: Pepper wilt is one of the main diseases of pepper. At the early stage of disease, a large number of lower leaves fell off, and water-stained decay was found on the base of the stem near the surface. Sometimes the disease occurs only on one side of the plant, resulting in longitudinal, stripe-shaped necrosis. The aboveground stems and leaves quickly dehydrate and necrosis and show a blue and dry form. Finally, the whole plant dies. The root system of the diseased plant was also watery and rotted like the base of the stem. The cortex was easily peeled off, and the lignified part of the root system turned dark brown. In wet conditions, white moldy plants grew on the diseased part. Control measures: 1 Strengthen field management. Cultivate strong and strong seedlings, cultivate high glutinous rice, prevent flooding, and do not make continuous crops. 2 chemical control. In the initial stage of disease, spray 50% carbendazim WP 500 times, or 40% polysulfide suspension 600 times, or 14% urea ammonia solution 300 times to irrigate the roots. The average per irrigation solution is 250 grams. The degree of occurrence of disease, continuous irrigation 2 to 3 times.
