摘　　要：小麦赤霉病已成为当前制约我国小麦生产安全及麦类食品质量安全的最重要的病害之一。本文分析了当前我国小麦赤霉病发生及危害现状,解析了赤霉病频繁暴发危害的原因,综述了国内外小麦赤霉病防控研究进展。针对当前形势,提出"立足预防、分区施策、全程防控"的赤霉病防控对策建议。Fusarium head blight（FHB）caused by Fusarium graminearumspecies complex has emerged as the most serious disease on wheat in China.FHB causes not only yield losses but also mycotoxin contamination in infested grains that poses a serious threat to human and animal health.Here,we summarize the situation of FHB occurrence and damage in China,and analyze the major reasons of FHB outbreaks during the last decades.In addition,we highlight the advances in resistance breeding,mechanisms of fungal pathogenicity and mycotoxin biosynthesis,and chemical control of this disease.Finally,we propose a technical approach for management of FHB,which is based on the prevention and control of FHB by using distinct strategies in different regions during the whole growth stage of wheat.
