Embodiment 1

[0030] 16% Fluoramide·Difenoconazole Ultra-Low Volume Liquid (Preparation 1, Fluoramide: Difenoconazole=1:15)

[0031] Fluoramide 1%, Difenoconazole 15%, Octylphenol Polyoxyethylene Ether 4%, Calcium Dodecylbenzene Sulfonate 4%, N-Methylpyrrolidone 12%, Dimethylsulfoxide 8%, Oil Acetate methyl ester supplemented to 100%. Mix the above-mentioned original drug, solvent, and emulsifier in proportion, and stir evenly to obtain a 16% fluamide difenoconazole ultra-low volume liquid.

Embodiment 2

[0033] 10% Fluoramide Difenoconazole Ultra-Low Volume Liquid (Preparation 2, Fluoramide: Difenoconazole = 9:1)

[0034] Fluoramide 9%, Difenoconazole 1%, Octylphenol Polyoxyethylene Ether 3%, Calcium Dodecylbenzene Sulfonate 2%, N-Methylpyrrolidone 12%, Dimethylsulfoxide 8%, C10 Aromatics make up to 100%. Mix the above-mentioned original drug, solvent, and emulsifier in proportion, and stir evenly to obtain a 10% fluamide difenoconazole ultra-low volume liquid.

Embodiment 3

[0036] 31% Fluoramide Difenoconazole Sustained Release Granules (Preparation 3, Fluoramide: Difenoconazole=30:1)

[0037] Fluoramide 30%, Difenoconazole 1%, Polyvinyl Alcohol 5%, Cross-linked Starch 2%, Silica 3%, Polyoxyethylene Styryl Phenyl Ether 2%, Water 4%, Clay Supplement 100 %. Mix cross-linked starch with water and heat for 60 minutes, then add fluoroamide, difenoconazole, polyoxyethylene styryl phenyl ether, mix at 50 degrees Celsius at 2000 rpm for 5 minutes, then heat at 30 degrees Celsius Solidify under high temperature for 5 hours, then dry and pulverize, add clay and polyvinyl alcohol to granulate through a disc granulator at a speed of 60 rpm, and pass through a grading sieve to obtain the required particle size, that is, to obtain 31% fluoroamide phenyl ether Metroconazole extended-release granules.

Abstract

The invention relates to an agricultural bactericide composition containing Flutolanil and difenoconazole. The bactericide composition comprises Flutolanil and difenoconazole as effective ingredients and is prepared by compounding the two ingredients, wherein the weight ratio of Flutolanil to difenoconazole is 1:50-50:1, and the total weight of Flutolanil and difenoconazole in the bactericide composition accounts for 5-60% of the total weight of the bactericide composition. The bactericide composition disclosed herein is suitable for controlling various diseases of cereal crops, especially for controlling rice sheath blight disease, false smut and the like; compared with using single dose, significant synergistic effect is achieved; the application dosage of pesticides is reduced, the pesticide cost is reduced, the generation of pesticide resistance is delayed, and the adverse impact of the pesticide to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an agricultural fungicide composition containing fluoroamide and difenoconazole, which can be used for preventing and controlling agricultural plant diseases. Background technique [0002] Rice is one of the main food crops in my country, and its planting area ranks first in the country, accounting for 1 / 4 of the country's arable land. However, during the whole growth process of rice, it faces many threats such as diseases, insects, weeds and other pests, among which the damage of rice diseases seriously affects the rice production in our country. [0003] Sheath blight is one of the important diseases in rice production in my country. The disease can produce a large number of sclerotia and overwinter in the soil. In the second year, the sclerotia adheres to the base of the rice plant to complete the initial infection, and then the mycelium continues to spread and form a re-i...
