Embodiment 1

[0029] Example 1, the bactericidal effect of the mixed medicament of oxastrobin and difenoconazole

[0030] 1. Drug preparation

[0031] The enoxastrobin (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] 9 kinds of mixed medicaments used in the present embodiment are prepared according to the following method:

[0033] Dissolve enoxastrobin and difenoconazole respectively in dimethyl sulfoxide to make 1.0×10 4 μg / mL stock solution for later use. The two mother liquors of enoxastrobin and difenoconazole according to 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 ratios 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 mixtur...

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 enoxastrobin and difenoconazole 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, and it is also the most important food crop in my country. The total area, total yield and yield per unit area of ​​rice rank first among grain crops in my country. 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 ric...
