Abstract

The invention relates to a fungicidal composition with chlorothalonil and triazole compounds, which comprises an active component A and an active component B, wherein the active component A is selected from chlorothalonil, and the active component B is selected from one of bitertanol, metconazole, triticonazole, ipconazole, or fenbuconazole; the weight ratio of the effective active component A and B is 1-80%:1-60%; additives and excipients are added into the effective active components to prepare wettable powder, water dispersible granules, suspending agents, suspending emulsions, or suspending seed coating agents; the invention is applicable to the control of powdery mildew, botrytis, downy mildew, rice blast, glume blight, rust disease, anthracnose, alternaria mali roberts, rot disease, brown rot, scab, leaf spot, epidemic diseases, melasma, brown spot disease, scab disease, and leaf blight, is low in drug dose, is rainwash resistance, and has obvious synergistic effect.

Description

Technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a bactericidal composition containing chlorothalonil and triazole compounds on crop diseases. technical background [0002] Chlorothalonil, English name: chlorothalonil Molecular formula: C 8 Cl 4 N 2 Chemical name: Tetrachloroisophthalonitrile (2,4,5,6-tetrachloro-1,3-phthalonitrile), structural formula: [0003] [0004] Chlorothalonil is a non-systemic broad-spectrum fungicide, which has a preventive effect on a variety of crop fungal diseases. It can bind to the cysteine ​​protein in the glyceraldehyde 3-phosphate dehydrogenase in fungal cells, destroy the metabolism of the cell and lose its vitality. Its main function is to prevent fungal infection, without systemic conduction, but has good adhesion on the surface of plants, is not easy to be washed by rain, and has a longer efficacy period. [0005] Bitertanol (bitertanol), molecular formula: C 20 H 23 N 3 O 2 ,...
