example 1

[0026] Dissolve 5% cypermethrin and 0.2% D-trans-permethrin in 10% trimethylbenzene solvent and 2% piperonyl butoxide, then put 2% Span-60#, 6% Nongru 602 #, stir until fully mixed, shear with a high-speed shear emulsifier, add 5% propylene glycol, 0.5% organic silicon defoamer during the shearing process, make up deionized water to 100%, and finally get 5.2% cypermethrin. D-trans permethrin emulsion in water.

example 2

[0028] Dissolve 6% cypermethrin and 0.6% D-trans-permethrin in 15% pentamethylbenzene solvent, then put 2% Nongru 500#, 4% Nongru 1600#, 6% Ningru 36# , stir until fully mixed, shear with a high-speed shear emulsifier, add 2% urea, 0.3% organic silicon defoamer during the shearing process, make up deionized water to 100%, and finally get 6.6% cypermethrin. Spin-trans permethrin emulsion in water.

example 3

[0030] Dissolve 1% beta-cypermethrin and 2% D-trans-permethrin in 8% pentamethylbenzene solvent, then put in 2% Span-60#, 6% Nongru 34#, stir until fully mixed , use a high-speed shearing emulsifier to shear, add 3% ethylene glycol, 0.3% silicone defoamer during the shearing process, make up deionized water to 100%, and finally get 3% beta-cypermethrin·dextrorotary trans Emulsion of permethrin in water.

Abstract

The invention relates to compound insecticide containing d-trans-prallethrin chloride, which comprises, in weight percentage, 1-10% of lethal pyrethroid compound shown in a formula (A), 0.1-2% of d-trans-prallethrin chloride, 3-20% of emulsifier, 5-25% of cosolvent, 1-10% of antifreezing agent, 0.1-0.5% of defoaming agent, and the balance of water. The compound insecticidal preparation is simple in production process and safe in use, consumption of organic solvent is reduced, environmental pollution is reduced, the rate of downing sanitary insect pests such as mosquitoes, flies, cockroaches and the like can be increased, and fine lethality rate is achieved. In addition, the compound insecticide has evident synergetic effect on controlling the sanitary insect pests, application amount of insecticides can be reduced, cost can be reduced, and occurrence of drug resistance of the sanitary insect pests can be delayed.

Description

technical field [0001] The invention relates to an insecticide, in particular to a compounded pesticide insecticide, especially a compounded insecticide containing D-trans permethrin. Background technique [0002] 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 resistance to sanitary pests. Through the compounding of two pesticides, this will not only improve the control effect on sanitary pests, but also be economical and convenient, and delay the development of resistance to sanitary pests. produce.
