Embodiment 1

[0029] Example 1. The bactericidal effect of the mixed medicament of fenoxastrobin and difenoconazole

[0030] 1. Preparation of medicament

[0031] The difenoconazole (98%) used in this example was purchased from Shenyang Research Institute of Chemical Industry, and the difenoconazole (95%) used in this example was purchased from Jiangsu Qizhou Green Chemical Co., Ltd.

[0032] The 9 compounding agents used in this example were prepared according to the following method:

[0033] Dissolve ketoxifen and difenoconazole in dimethyl sulfoxide to make 1.0×10 4 μg / mL mother liquor is reserved. The two mother liquors of oxystrobin and difenoconazole were made according to the volume ratio 1:9, 2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2, 9 :1 A total of 9 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 compounding agents, and set the concentration of each compounding agent to 0, 0.05, 0.1, 0...

Abstract

The invention discloses a bactericide of Ustilaginoidea virens or a reagent for prevention and treatment of Ustilaginoidea virens. The active ingredients of the reagent are composed of (E, E, E)-N-methyl-2-[((((1-methyl-3-(2, 6-dichlorophenyl)-2-allyl)imino)oxy)methyl)phenyl]-2-methoxyimino acetamide and (RS)-3-chloro-4-[4-methyl-2-1H-1, 2, 4-triazole-1-ylmethyl)-1, 3-dioxylpentane-2-yl)phenyl-4-chlorophenyl ether that are in a mss ratio of 1-4:9-6 or 7:3. The reagent provided by the invention solves the drug use problem in actual rice production, and has wide application prospects in the field of agricultural bactericides. The application of novel agents and blending of reagents with different action mechanisms help delaying the generation of drug resistance, and the reagent has significant social benefits.

Description

Technical field [0001] The invention relates to a mixed medicament of difenoxan and difenoconazole for preventing and treating rice smut disease, belonging to the technical field of pesticides. Background technique [0002] Rice is one of the most important food crops in the world and also the most important food crop in my country. The total area, total output and output per unit area of ​​rice all rank first in my country's 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 smut is an important disease in the process of rice production, and the disease 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 areas and the changes in cultivation methods, the occurrence of rice smut has been increasing year by year. The disease mainly damages rice ears, forming ...
