Triadimenol and difenoconazole mixed medicament for preventing ustilaginoidea virens

Abstract

The invention discloses bactericide of ustilaginoidea virens or medicament for preventing ustilaginoidea virens. The active components of the medicament comprise 1-(4-chlorobenzene oxygroup)-3, 3-dimethl-1-(1H-1, 2, 4-triazole-1-radical)-2-butanol and (RS)-3-chlorine-4-[4-methyl-2-1H-1, 2, 4-triazole-1-radical methyl]-1, 3-dipentane-2-radical)phenyl-4-chlorobenzene ether, wherein the mass ratio of 1-(4-chlorobenzene oxygroup)-3, 3-dimethl-1-(1H-1, 2, 4-triazole-1-radical)-2-butanol to (RS)-3-chlorine-4-[4-methyl-2-1H-1, 2, 4-triazole-1-radical methyl]-1, 3-dipentane-2-radical)phenyl-4-chlorobenzene ether is 1-9: 9-1. The medicament solves the rice pharmacy problem in the actual production, and has wide application prospects in the field agricultural bactericide. The economic benefit can be obtained through implementing industrialization; the generation of relaying drug resistance is helpful through the application of novel medicament and the mixing of medicament with different action mechanisms; the medicament has prominent social benefit.

Description

technical field [0001] The invention relates to a mixed agent of triadimenol and difenoconazole for preventing and treating rice smut, and belongs to the technical field of pesticides. Background technique [0002] In the process of rice production, rice diseases are the main factors restricting the yield and quality of rice. Rice false smut is an important disease in rice production, which occurs in all rice producing areas in the world. Since the 1980s, with the continuous replacement of rice varieties in my country, the expansion of hybrid rice planting area and the change of cultivation methods, the occurrence of rice smut has been increasing year by year. At present, the disease has developed into one of the most important diseases of rice in my country. The disease mainly damages rice spikes and forms rice curve balls on the grains, resulting in yield reduction; it can reduce the nutrient transport of adjacent rice grains and produce toxins, which has a huge impact o...

Problems solved by technology

[0005] Whether it is triadimenol, difenoconazole, or other high-efficiency fungicides, long-term single use will easily cause disease resistance, resulting in reduced control effects, shortened duration of efficacy, and increased dosage, which is not conducive to environmental sustainability. sustainable development
