Abstract

The invention discloses a bactericidal composition containing tebuconazole and imazalil and application of the bactericidal composition. The effective components of the bactericidal composition disclosed by the invention contain tebuconazole and imazalil, wherein the mass ratio of tebuconazole to imazalil is (20: 1)-(1: 20). Tebuconazole and imazalil are compounded for use, the action mechanisms of the effective components are different, the bactericidal control spectrum is expanded, the synergistic interaction is remarkable, and the generation of drug resistance of pathogenic bacteria is delayed. The invention also discloses application of the synergistic bactericidal composition in prevention and treatment of diseases of wheat, rice, grapes, strawberries, tomatoes and mulberries. The bactericidal composition has obvious effects on prevention and treatment of wheat scab, wheat powdery mildew, wheat rust, rice bakanae disease, rice seedling rot, grape gray mold, strawberry anthracnose, tomato leaf mold, mulberry sclerotiniose and other diseases, has obvious synergism, reduces pesticide consumption, has synergism, and is environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of fungicides, in particular to a bactericidal composition containing tebuconazole and imazalil and application thereof. Background technique [0002] Fusarium head blight (FHB), caused by Fusarium graminearum species complex, causes serious damage to both wheat and barley worldwide. The occurrence and prevalence of wheat scab is mainly related to factors such as wheat growth period, climatic conditions, and bacterial sources. Wheat can be damaged at all stages of growth. Infection at the seedling stage causes seedling rot, and infection in the middle and late stages causes stem rot and ear rot. Ear rot is the most harmful, resulting in loss of wheat yield and quality decline. In addition, wheat diseased kernels contain deoxynivalenol (DON) and its acetylated derivatives, 3-acetyl-deoxynivalenol (3A-DON) and 15-acetyl-deoxynivalenol (15-acetyl-deoxynivalenol, 15A-DON), nivalenol (nivalenol) and T2 toxin, a...
