Kresoxim-methyl sterilizing aqueous emulsion and preparation method thereof

Abstract

The invention discloses a kresoxim-methyl sterilizing aqueous emulsion and a preparation method thereof. Based on the weight percentage, the formulation of the components of the kresoxim-methyl sterilizing aqueous emulsion comprises: 1%-40% of kresoxim-methyl technical product of pesticides, 10%-30% of solvent, 2%-5% of anionic emulsifier, 2%-5% of nonionic emulsifier, 1%-5% of antifreezing agent, 0.1%-0.5% of defoaming agent and the balance water. The preparation method comprises: the kresoxim-methyl technical product of pesticides, the solvent and the emulsifier are mixed together to be dissolved into even oil phase; and the water, the antifreezing agent and the defoaming agent are mixed together to form uniform water phase. The water phase is mixed with the oil phase under the high speed agitation to produce the products of the kresoxim-methyl sterilizing aqueous emulsion which has remarkable drug effects on powdery mildew, scab, downy mildew, early blight and late blight of fruit trees and vegetables. The sterilizing aqueous emulsion does not have chemical injury for the safety of environment, people and animals as well as other beneficial living creatures, and has the advantages of being simple in preparing technique and suitable for large-area generalization and application.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a control effect for fruit trees and vegetables against powdery mildew, scab, downy mildew, early blight and late blight, in particular to a kresoxim-methyl emulsion in water and a preparation method thereof. Background technique [0002] In recent years, great changes have taken place in global pesticide policies, especially the strict restrictions on the use of highly toxic and high residue pesticides in developed countries. For a long time, pesticide emulsifiable concentrates and wettable powders have been important dosage forms of pesticide preparations. However, since the emulsifiable concentrates contain a large amount of flammable organic solvents, a large amount of organic solvents will volatilize into the atmosphere during long-term use, causing serious damage to the environment. The pollution of wettable powder contains a large amount of dust, which is harmful to produ...

Problems solved by technology

For a long time, pesticide emulsifiable concentrates and wettable powders have been important dosage forms of pesticide preparations. However, due to the large amount of flammable organic solvents contained in the emulsifiable concentrates, a large amount of organic solvents will evaporate into the atmosphere during long-term use, causing serious damage to the environment. The pollution of wettable powder contains a lot of dust, which is harmful to producers and users. All these problems have attracted widespread attention
