Abstract:In order to clarify the occurrence regularity of wheat sharp eyespot in Yantai area,the occurrence of wheat sharp eyespot at different growth stages in field was investigated using the five point sampling method,and the resistance of different varieties to wheat sharp eyespot was identified by preliminarily confirming the relationship between disease occurrence and meteorological factor.The results showed that the wheat sharp eyespot were detected during all the growth stages of wheat from wintering period in 9 counties of Yantai area.The incidence at peak stage was 60.63% to 81.28%.The incidence was the highest in Laizhou and the lowest in Longkou.The wheat sharp eyespot could be found from seedling stage to maturity stage in Yantai area,which was closely related to temperature,rainfall and humidity.In 31 wheat varieties,there were no immune,high resistance and medium resistant varieties,9 moderately susceptible varieties,and 22 high susceptible varieties.
