Many years of continuous cropping caused the serious occurrence of potato scab,and the lack of resistant varieties and special control agents in production made it difficult to control the disease.The occurrence characteristics of scab disease are analyzed from three aspects:the classification of Streptomyces causing scab disease and the characteristics of pathogenic factors,the resistant varieties of potato and identification methods,the physical and chemical properties of soil and soil microecology.A comprehensive control strategy for scab disease is proposed,which provided ideas for the study of the pathogenesis of scab disease and the comprehensive prevention and control in the field.
