摘　　要：通过比较不同用量、不同噁霉灵药剂产品对防治番茄枯萎病的效果,探索噁霉灵防治番茄枯萎病的田间药效。结果发现,施用基肥时,0.1%噁霉灵颗粒剂防治效果因施用量的增大而提高,且施用简便、省时,每667 m^(2)节省成本375元左右。植株发病初期,采用70%噁霉灵可湿性粉剂喷雾能控制病害的发生,但盛果期发病时田间操作难度大。综合考虑,0.1%噁霉灵颗粒剂可有效防治番茄枯萎病,同时降低单位面积生产成本,提高种植效益。By applying different dosages and different hymexazol products,the field efficacy of hymexazol on the control of tomato Fusarium wilt was investigated.The results showed that the control effect was improved with the increase of application amount when applying 0.1%hymexazol granule together with base fertilizer.The application method was simple and time-saving.The cost was decreased by 375 yuan per 667 m^(2) compared with the traditional application method.At the early stage of the disease,spraying 70%hymexazol wettable powder could control the disease,but the application method was difficult to operate at fruit-setting stage.Taken together,the application of 0.1%hymexazol granule can effectively control tomato Fusarium wilt and reduce the production cost.
