Wheat scab is a fungal disease. How to control it?

Wheat scab is a fungal disease. How to control it? Wheat scab is also called ear blight and red head disease. Wheat scab is most likely to occur at heading and flowering stage, and it will not have serious consequences until filling stage. However, it is difficult to control the disease when other diseases occur, so we should focus on preventing wheat scab. Wheat is harmed by scab from seedling stage to heading stage, among which ear rot is the most serious. When scab invades wheat ear axis, it will cause withering and white ear above the damaged part, so it is also called "half ear", which is also one of the important characteristics of wheat scab recognition. When the humidity is high, a red or pink mold layer can be seen on the surface of the diseased tissue.

Choosing disease-resistant varieties, one of the reasons for wheat scab is that fertilizer-intolerant and late-maturing varieties are susceptible to infection, so when planting, we should choose varieties with strong disease resistance. When choosing wheat varieties, you should ask the local agricultural stores. Basically, they all know the relevant varieties and choose the suitable varieties to plant locally according to local conditions. There are many drugs that use pesticides to control wheat scab, such as carbendazim, fast poly, kebaijun, Surek, etc., which have strong control effects on wheat scab. The prevention and control of wheat scab should focus on the flowering period of wheat. Buying pesticides at flowering stage and spraying them according to relevant drug standards can effectively prevent wheat scab.

Rational irrigation and rational use of fertilizer One of the reasons for the formation of wheat scab is that it is necessary to carry out reasonable drainage because of poor drainage. Reasonable irrigation should be carried out in combination with local soil moisture. Of course, if there is too much water in the soil, it should also be drained. Rational use of nitrogen fertilizer can make wheat plants have higher disease resistance. In the process of planting wheat, we should be able to prevent and treat common diseases. Communicate with local agricultural institutions and agricultural technicians to understand the relevant prevention and control work, otherwise it is difficult to have high yield of wheat only by extensive management.
