D-trans-propargyl chloride permethrin-containing compound insecticide preparation and application thereof

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 divisional case of a patent application with an application date of April 1, 2012, an application number of 201210098430.2, and an invention title of "a compound insecticide preparation containing dextro-trans permethrin and its application" Apply. technical field [0002] The invention relates to an insecticide, in particular to a compounded pesticide insecticide, especially a compounded insecticide containing D-trans permethrin. Background technique [0003] For a long time, most of the pesticides used to prevent and control sanitary pests in the external environment are pyrethroid single agents. The long-term use of pyrethroid single agents makes hygienic pests such as mosquitoes, flies, cockroaches, etc., greatly resistant to pyrethroids. In recent years, there has been a general decrease in the control effect. Therefore, there is a need for an environmentally friendly and efficient pesticide compound variety to delay the emergence of resist...

Problems solved by technology

[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
