Barley grains are highly susceptible to fungal contamination. Fungal infection of its kernels occurs in the field and is often associated with Fusarium species, which are phytopathogenic fungi. These fungi cause variety of diseases such as Fusarium head blight (FHB). FHB is one of the most studied diseases, which is responsible for worldwide losses in small-grain cereals. Losses are manifested as reduction in yield and quality of the grain, and the presence of mycotoxins in grain. Moreover, mycotoxins produced by the FHB pathogens are one of the most important groups of anti-nutritional substances found in feed. They are hazardous to animal and human health. Cases of mycotoxicosis caused by ingestion of barley contaminated with FHB mycotoxins have necessitated the need for resistant barley cultivars. That can limit mycotoxin production by the dominant causal pathogen, Fusarium graminearum. Various inoculation methods have been used to decrease the severity of the disease. Resistant cultivars and proper management of prevention methods could reduce damage from FHB. This review examines the progress of FHB resistance in barley, as well as, prevention methods. A combination of cultural practices, planting resistant varieties, chemical control, biological control and harvesting strategies is required. Combining these aspects leads to quality grain production and protects human and animal health.
