Problems solved by technology

[0003] The conventional dosage form of flusilazole is emulsifiable concentrate, but the emulsifiable concentrate preparation consumes a large amount of organic solvents, which not only increases production and use costs, but also easily leads to environmental pollution and phytotoxicity of young leaves and fruits, and does not meet the requirements for the development of green and environmentally friendly pesticides. With the increasing awareness of people's environmental protection and the requirements for the development of green food

example 1

[0019] Weigh 5.0Kg of flusilazole, 3.0Kg of xylene, 3.0Kg of soybean oil, 5.0Kg of alkylbenzene sulfonate, 4.0Kg of propylene glycol, and make up to 100Kg with water. During preparation, mix and heat flusilazole, xylene, soybean oil, and alkylbenzene sulfonate until completely dissolved to form an oil phase; mix propylene glycol and water to form a water phase. Slowly add the water phase to the oil phase under stirring, and stir (or homogenize) rapidly for 30-60 minutes. The average particle size measured by a laser particle size analyzer was 1.2 microns.

example 2

[0021] Weigh 10.0Kg of flusilazole, 5.0Kg of methanol, 5.0Kg of soybean oil, 5.0Kg of alkylbenzenesulfonate, 3.0Kg of phenethylphenol polyoxyethylene ether, 4.0Kg of ethylene glycol, and make up to 100Kg with water. During preparation, mix and heat flusilazole, methanol, soybean oil, alkylbenzene sulfonate, phenethylphenol polyoxyethylene ether until completely dissolved to form an oil phase; mix ethylene glycol and water to form a water phase. Slowly add the water phase to the oil phase under stirring, and stir (or homogenize) rapidly for 30-50 minutes. The average particle size measured by a laser particle size analyzer is 1.6 microns.

example 3

[0023] Weigh 15.0Kg of flusilazole, 7.0Kg of xylene, 5.0Kg of rapeseed oil, 4.0Kg of phenethylphenol polyoxyethylene ether, 8.0Kg of castor oil polyoxyethylene ether, 4.0Kg of ethylene glycol, and make up to 100Kg with water. During preparation, mix and heat flusilazole, xylene, rapeseed oil, castor oil polyoxyethylene ether, and phenethylphenol polyoxyethylene ether until completely dissolved to form an oil phase; mix ethylene glycol and water to form a water phase. Slowly add the water phase to the oil phase with stirring, and stir (or homogenize) rapidly for 30-45 minutes. The average particle size measured by a laser particle size analyzer is 1.5 microns.

Abstract

The invention relates to an agricultural preparation, in particular to a flusilazole-containing aqueous emulsion which consists of 2 percent to 30 percent of flusilazole, 5 percent to 20 percent of solvent, 5 percent to 15 percent of surfactant, 1 percent to 6 percent of antifreeze and the balance of the water. The bactericidal aqueous emulsion pertains to an environment-friendly bactericide, performs protective and therapeutic treatment actions, and especially has good effects in protecting and treating apple scab, apple powdery mildew and the like.

Description

technical field [0001] The invention relates to a new pesticide dosage form, in particular to a water emulsion containing fluorosilazole. Background technique [0002] Flusilazole, a triazole fungicide, is a sterol demethylation inhibitor. This internal fungicide is effective for Ascomycetes, Basidiomycetes and Deuteromycetes, but not for Oomycetes. Recommended It is used to prevent and control apple scab, powdery mildew, black powdery mildew of cereals, Septoria spp., vine hookworm, Staphylococcus spp., and various pathogenic bacteria on various crops such as sugar beet. [0003] The conventional dosage form of flusilazole is emulsifiable concentrate, but the emulsifiable concentrate preparation consumes a large amount of organic solvents, which not only increases production and use costs, but also easily causes environmental pollution and phytotoxicity of young leaves and fruits, and does not meet the requirements for the development of green and environmentally friendly p...
