Since most of the areas since March, the weather is normal and the sunshine is sufficient. The relative humidity of the soil is basically maintained at 70-80. %, climatic conditions are conducive to the formation of diseased ascospores. It is expected that the meteorological conditions along the Huaihei River in Anhui Province in 2011 are not suitable for the occurrence and development of winter wheat scab; the meteorological conditions between the Jianghuai are basically suitable for the development of wheat scab.
