Embodiment 1

[0033] Example 1, the bactericidal effect of triadimenol and erythrostrobin mixed medicament

[0034] 1. Drug preparation

[0035] The triadimenol (≥97%) used in this example was purchased from Jiangsu Jianpai Pesticide Chemical Co., Ltd., and the enoxastrobin (98%) used in this example was purchased from Shenyang Research Institute of Chemical Industry.

[0036] 9 kinds of mixed medicaments used in the present embodiment are prepared according to the following method:

[0037] Dissolve triadimenol and enoxastrobin respectively in dimethyl sulfoxide to make 1.0×10 4 μg / mL stock solution for later use. The two mother liquors of triadimenol and enoxastrobin were mixed according to the volume ratio of 1:9, 2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2, 9:1 Nine different proportions are mixed to form a mixed mother liquor. Then use dimethyl sulfoxide to dilute each mixed mother liquor into a series of concentration mixtures. Based on the preliminary experiment, the concentration of each ...

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...
