Current situation and management strategies of Fusarium head blight in China

Fusarium head blight (FHB) caused by Fusarium graminearum species 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.
