A compound insecticide preparation containing dextro-trans permethrin and its application

Abstract

The invention relates to d-trans-propargyl chloride permethrin-containing compound insecticide and an application thereof. The d-trans-propargyl chloride permethrin-containing compound insecticide comprises the following components in percentage by weight: 1-10% of fatal permethrin compound as described in a formula (A), 0.1-2% of d-trans-propargyl chloride permethrin, 3-20% of an emulsifying agent, 5-25% of a cosolvent, 1-10% of an antifreezing agent, 0.1-0.5% of a deforming agent and the balance being water, wherein R1 and R2 in the formula (A) is methyl, chlorine or bromine, Z is H or a cyano group, and the cosolvent is one or a mixture of piperonyl butoxide, trimethylbenzene, tetramethylbenzene or pentamethylbenzene. The d-trans-propargyl chloride permethrin-containing compound insecticide is simple in production process and safe to use; the dosage of an organic solvent is reduced; the pollution to environments is reduced; the knock-down rate of the d-trans-propargyl chloride permethrin-containing compound insecticide for sanitary pests such as mosquitoes, flies and cockroaches is increased, and the relatively high fatality rate is realized; the d-trans-propargyl chloride permethrin-containing compound insecticide has a remarkable synergistic effect on prevention and control of the sanitary pests; the application amount of the insecticide preparation can be reduced; the cost is saved; the generation of pesticide resistance of the sanitary pests is delayed.

Description

[0001] This application is a division of a patent application whose application date is April 1, 2012, application number is 201210098430.2, and invention title is "a compound insecticide containing dextro-trans-chlorpropin and its application" Application. Technical field [0002] The invention relates to an insecticide, in particular to a compound pesticide pesticide, in particular to a compound pesticide containing dextro-trans chlorpropargyl. Background technique [0003] For a long time, most of the agents used to prevent and control sanitary pests in the external environment are pyrethroid single agents. The long-term use of pyrethroid single agents makes sanitary pests such as mosquitoes, flies, cockroaches, etc. more resistant to pyrethroid agents. In recent years, there has been a general decrease in the prevention effectiveness. Therefore, an environmentally friendly and efficient pesticide compound variety is needed to delay the development of health pest resistance. T...

[0003] For a long time, most of the medicaments used to prevent and control hygienic pests in the external environment are single-dose pyrethroids. The long-term use of single-dose pyrethroids makes hygienic pests such as mosquitoes, flies, and cockroaches more resistant to pyrethroids. In recent years, there has been a phenomenon that the control effect has generally decreased
