Abstract: Scab disease is one of the common diseases of potatoes at present,and it is a serious soil borne disease that widely occurs in China and even around the world.Infected potato tubers will produce concave or convex spots,which can cover the entire tuber in severe cases.The appearance and phenotype of the entire tuber will deteriorate,the overall quality will decrease,and it is not resistant to storage and is prone to decay.Potatocommon scab has become a major disease that restricts potato production in China,greatly limiting the development progress of the potato industry in China.Therefore,research on potato common scab is becoming increasingly important.This article summarized the symptoms,pathogenesis,mechanism,prevention and control measures and methods of potato common scab disease, and provided prospects for future research on potato scab resistance.
