小麦根病是由长蠕孢菌、全蚀病菌、镰刀菌等多种致病菌复合侵染的一种根腐病,往往造成小麦减产10～80％,严重地威胁小麦的生产。我们在以前试验的基础上,采用内吸性杀菌剂羟锈宁、粉锈宁进行拌种试验和大田示范,平均防效可达60％左右,保产效果为17％左 Wheat root disease is a root rot caused by compound infection of a variety of pathogenic bacteria, such as C. longum, total ectomycorrhizal fungi and Fusarium, which often results in 10-80% reduction of wheat yield and seriously threatens wheat production. On the basis of the previous experiments, we used the systemic fungicides Hydroxyphenylalanine and Triptorelin for seed dressing experiments and Daejeon demonstration with an average control efficiency of 60% and a guaranteed effect of 17%
