Soybean cyst nematode(SCN)disease is a serious disease in soybean production,causing significant production and economic losses.At present,screening and planting disease resistant varieties,agricultural control,biological pest control and chemical control are common control methods in integrated control of SCN.In terms of disease resistance research,the rhg1 and rhg4 loci in soybeans are the most important resistance sites to SCN disease.This article reviews recent research on SCN disease in order to provide reference for the study of SCN resistance mechanisms and the improvement of prevention and control techniques.
