A novel pesticide composition containing prothioconazole and triazoles

Abstract

The invention relates to a novel pesticide composition containing prothioconazole and triazoles, which comprises active ingredient A and active ingredient B, wherein active ingredient A is selected from prothioconazole, and active ingredient B is selected from epoxiconazole , Hexaconazole, 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, micro Emulsion, used to control powdery mildew, sheath blight, rice false smut, leaf spot, rust, sclerotinia, spotted leaf spot, gray mold, flax spot, scab, black spot, brown spot, For diseases such as black rot, it has the effects of small dosage, resistance to rain erosion, and obvious synergistic effect.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and relates to the application of a novel pesticide composition containing prothioconazole and triazoles on 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 bacter...

Examples
