Mixture of Triadimenol and Enoxastrobin for Controlling Rice Smut

Abstract

The invention discloses a fungicide of Ustilaginoideavirens or a drug for preventing and treating Ustilaginoideavirens. The active ingredients are composed of 1-(4-chlorophenoxy)-3, 3-dimethyl-1(1H-1, 2, 4-triazole-1-yl)-2-butanol and (E, E, E)-N-methyl-2-[((((1-methyl-3-(2, 6-chlorophenyl)-2-allyl) imino) oxygroup) methyl) phenyl]-2-methoxy imino acetamide, wherein the mass ratio of the 1-(4-chlorophenoxy)-3, 3-dimethyl-1(1H-1, 2, 4-triazole-1-yl)-2-butanol to the (E, E, E)-N-methyl-2-[((((1-methyl-3-(2, 6-chlorophenyl)-2-allyl) imino) oxygroup) methyl) phenyl]-2-methoxy imino acetamide is (2-6): (8-4) or (9:1). The triadimenol and syp-1620 mixed drug disclosed by the invention solves the drug use problem in practical rice production and has a wide application prospect in the field of agricultural fungicide. Industrialization is carried out on the triadimenol and syp-1620 mixed drug to bring economic benefit, novel drug is adopted and drugs with different action mechanisms are mixed to beneficially delay the generation of resistance to drugs, and the triadimenol and syp-1620 mixed drug has remarkable economic, ecological and social benefits.

Description

technical field [0001] The invention relates to a mixed medicament of triadimenol and enoxastrobin for preventing and treating rice false smut, and belongs to the technical field of pesticides. Background technique [0002] Rice is one of the most important food crops in the world. In my country, the total area, total output and output per unit area of ​​rice rank first among food crops. In the process of rice production, disease is the main factor restricting the yield and quality of rice, often causing huge economic losses. 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. The disease mainly damages rice spikes, and forms rice curve balls on the grains to reduce yield; it can reduce t...

Problems solved by technology

[0005] Regardless of whether it is triadimenol, enoxastrobin, or other high-efficiency fungicides, if used alone for a long time, it is easy to cause disease resistance, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to environmental sustainability. sustainable development
