Abstract

The invention discloses a bactericidal composition containing prothioconazole and thiocarbamate, the bactericidal composition containing active component A and active component B, the active component A is selected from prothioconazole, active Component B is selected from any one of the following fungicides: mancozeb, propineb, mancozeb or mancozeb, and the weight ratio of the two active components of A and B is 50:1-1:80. The composition of the invention can prevent crop scab, blight, downy mildew, powdery mildew, sheath blight, leaf spot, leaf spot, ring spot, rust and anthracnose, and has obvious synergistic effects Effect, and good safety for crops; also has the advantages of rain resistance, long-lasting efficacy, small dosage and so on.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the preparation and application of a fungicidal composition containing two active components. Background technique [0002] Prothioconazole, English name: prothioconazole, molecular formula: C 14 h 15 Cl 2 N 3 OS, chemical name: (RS)-2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl]-2,4-dihydro-1,2 , 4-triazole-3-thione. Prothioconazole is a new triazolethione systemic fungicide, which acts as a demethylation inhibitor (DMI) to inhibit the precursor of sterol in fungi - lanosterol in 14- or -Demethylation of methylene dihydrolanosterol at position 24. The active ingredient has excellent protective, curative and eradicative activity. [0003] Regardless of whether it is prothioconazole, zinc, zinc, zinc, mancozeb or other high-efficiency fungicides, if used alone for a long time, it is easy to cause resistance to the disease, resulting in increased dosage, redu...
