Last Updated: 2024/12/23, What are the common diseases of sesame? Please introduce the common diseases of sesame: first, the main diseases of sesame. Sesame stem blight, commonly known as "black root disease" and "black stem disease", is the most important disease in sesame production, with a general incidence of 10%, 15% and 60%, 80%, respectively, which mainly occurs in sesame flowering.

How to prevent from falling down when planting sesame? Please introduce the method of sesame lodging, which is the great enemy in sesame production. If sesame lodging is light, the yield will be reduced by 10% to 50% and heavy by 70%, which seriously affects the yield and quality of sesame and restricts the development of sesame production. To prevent sesame lodging, we must start from sowing. In addition to increasing the application of organic fertilizer and phosphorus and potassium fertilizer, spraying the inhibitory hormone paclobutrazol (early rather than late) in the true leaf stage of sesame 1-2 can inhibit the vegetative growth of sesame seedlings, promote the development of plant roots, increase and fasten the roots, reduce the height of legs and pods, and avoid the possibility of lodging caused by strong winds and heavy rains. The method is to spray 50 kg of water with 80 grams of paclobutrazol per mu. At this time, there are also early seedlings, if the whole seedling is not scattered, it will cause the young stem to grow up too fast, waste nutrition, and the plant is thin, shallow rooting, poor resistance, easy to lodge in the middle and later stage. Sesame seedlings should be dispersed immediately after emergence, the leaves should not touch each other, and the seedlings should be fixed in time during the period of 3-4 pairs of true leaves. In addition, 10-15 days after the first flowering of sesame, spraying 4-5g / mu of thalidomide could inhibit the ineffective flowering and capsule formation in the upper part, control the top growth, reduce the competition for plant nutrients in the upper ineffective capsule, enhance the nutrient supply of the effective capsule, and achieve the effect of capsule filling and yield increase.
