小麦赤霉病在穗期多雨、气候潮湿的长江中下游冬麦区和东北春麦区发生严重,在其他麦区也经常发生,引起损失较大。由于目前大面积生产上种植的主要为感病或中抗品种,化学防治仍是控制赤霉病的重要手段。生产上防治该病的药剂以多菌灵及其复配剂为主,长期使用已出现了抗药性,因此新品种的开发极为重要。另据南京农业大学对小麦赤霉 Wheat head blight occurs in rainy and wet climates in the middle and lower reaches of the Yangtze River winter wheat and northeastern China spring wheat serious occurrence in other wheat areas, causing a greater loss. Due to the current production of large-scale production of susceptible or moderately resistant varieties, chemical control is still an important tool to control scab. Production of the prevention and treatment of the disease with carbendazim and its compound-based drugs, long-term use has emerged resistance, so the development of new varieties is extremely important. According to Nanjing Agricultural University on wheat scab
