Problems solved by technology

However, the hygienic pests of this kind of products generally have certain drug resistance, and the effect is relatively poor. Even if the concentration of active ingredients in the dosage form is increased, a more suitable insecticide cannot be produced. Therefore, the selection of suitable insecticides is effective Composition is an important link

Abstract

The invention provides an insecticide composition and a preparation method and application thereof. An active ingredient of the insecticide composition is an ester compound expressed by the formula (Y) in the specifications, wherein X can be: (1) 3-(2-fluo-1-propenyl)-2,2-dimethyl cyclopropane radical, (2) 3-(2-cyano-1-propenyl)-2,2-dimethyl cyclopropane radical and (3) 3-(2-cyano-2-fluorovinyl)-2,2-dimethyl cyclopropane radical. The insecticide composition is prepared from the active ingredient, a stabilizing agent, a synergistic agent and a base material according to a certain proportion, wherein the compound (Y) accounts for 0.05 to 3.0 weight percent of the insecticide composition. The insecticide of the invention has perfect effect of preventing and controlling mosquitoes, flies, cockroaches, ants and other household pests. The invention also provides the preparation method and the application of the insecticide composition.

Description

technical field [0001] The invention relates to an insecticide composition, its preparation method and application, in particular to an insecticide composition formulated and processed from a special pyrethroid compound (Y). Background technique [0002] Pyrethroid compounds can be used to control mosquitoes, flies, cockroaches and other sanitary pests, and have high insecticidal activity. This is a well-known fact. The breeding around factories, garbage treatment plants, livestock houses, poultry houses, etc. has always been distressing. As a countermeasure to eliminate these pests, in addition to the use of insecticide formulations such as emulsions, oils, powders, and new insecticides, there is still a lack of one-time sustained effect. Therefore, it is hoped to develop some good products and formulations, namely As a space treatment agent, it lasts for a long time and spreads well, and it is a product that has a good effect even in an open space. [0003] The insectici...
