It is the most threatening disease for highland barley planting. It has a wide range, great harm and fast transmission speed, and often has a huge impact on the yield of highland barley. Stripe rust mainly damages the leaves of highland barley, and damages the leaf sheath part, stem and ear part, glume and awn of highland barley. In order to improve the yield and quality of highland barley and promote the economic benefits of farmers, it is very important to do a good job in the prevention and control of highland barley stripe rust.
