Research progresses of southern corn rust in China
Southern rust in corn is a fungal airborne disease caused by Puccinia polysora Underw..It is a major disease in the main corn production areas of China,seriously endangering the yield and quality of maize.Once it occurs,it is extremely difficult to control.This article reviews the harmfulness,influencing factors of epidemics,detection methods,pathogenic mechanisms,and control methods of southern corn rust in China in recent years.It also summarizes the genetic basis and germplasm resources of maize resistant to southern corn rust.This article proposes future research directions to provide references for the prevention and control of southern corn rust.
