Abstract

The invention relates to a bactericidal composition containing prothioconazole, which contains active ingredient A and active ingredient B, wherein active ingredient A is selected from prothioconazole, and active ingredient B is selected from thiophanate-methyl, multibacterium One of Ling and prochloraz, wherein the weight ratio of active ingredient A to active ingredient B is 1:80 to 80:1, made into wettable powder, water dispersible granule, suspending agent, suspoemulsion, water emulsion, Microemulsion, used to control powdery mildew, sheath blight, fusarium wilt, leaf spot, rust, sclerotinia, viral disease, anthracnose, gray mold, ring spot, bakanae disease, rice blast, early blight, Diseases such as green mold, pedicle rot, penicillium, flax spot, scab, blight, etc. have the characteristics of small dosage, resistance to rain erosion, and obvious synergistic effects.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a fungicidal composition containing prothioconazole to crop diseases. technical background [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. [0003] Prothioconazole is a new triadimefon systemic fungicide, which acts as a demethylation inhibitor (DMI) to inhibit the precursor of sterol in fungi - lanosterol at 14- or -24 Demethylation of methylene dihydrolanosterol. Through a large number of field efficacy tests, the results show that prothioconazole not only has good safety for crops, but also has a good effect on disease prevention and treatment, and has a significant increase in yield. Compared with triazole fungicides, prothioconazole has more Broad-spectrum bactericidal live, and lon...
