Problems solved by technology

[0002] For a long time, the pesticides used to prevent and control sanitary pests are all pyrethroid agents. The long-term use of a single agent of pyrethroids has greatly increased the resistance of sanitary pests such as cockroaches, hygienic mosquitoes and hygienic flies to pyrethroids. , in recent years there has been a general decline in the effectiveness of

Embodiment 2

[0031] Add 100 parts by weight of water to the mixture of 100 parts by weight of wood carbon powder, cornstarch and walnut kernel powder (5: 1: 4) and knead it into shape, then dry to form incense stick-shaped disc insecticidal substrate (diameter 14cm, thickness 4mm, a pair weighs 34g).

[0032] On the other hand, 0.25 parts by weight of beta-cypermethrin was dissolved in vegetable oil to obtain a solution containing 0.25w / v% of beta-cypermethrin.

[0033] Use a micro-syringe to draw 3.4ml of the above mixed solution and evenly drop it on the above disc-type mosquito-repellent-repellent insecticidal substrate, and then place it at room temperature for 5 hours to obtain a set of disc-type mosquito-repellent coil III with 0.025w / w% beta-cypermethrin.

Embodiment 3

[0050] Mix 0.3 parts by weight of perfluthrin and 59.7 parts by weight of methanol to prepare an insecticidal composition insecticidal solution, put the obtained solution into an aerosol can with a valve, and pass through the valve under pressurized conditions Inject 40.0 parts by weight of dimethyl ether into the aerosol can to obtain an insecticide aerosol II, which contains 0.3w / w% of perflumethrin.

[0051] Reference Example 4

[0052] 0.3 parts by weight of beta-cypermethrin and 59.7 parts by weight of methanol are mixed together to prepare an insecticidal composition insecticidal solution, and the obtained solution is put into an aerosol can with a valve, and the aerosol is injected through the valve under pressurized conditions. Inject 40.0 parts by weight of dimethyl ether into the tank to obtain an insecticide aerosol III, which contains 0.3w / w% of beta-cypermethrin.

Abstract

The invention relates to a composition containing etrafluorine ethofenprox and high-efficiency cypermethrin and application thereof, and provides a pesticidal composition for controlling health mosquitoes, health flies, Blattella germanica and other health pests, wherein the mass ratio of the tetrafluorine ethofenprox to the high-efficiency cypermethrin is 1:99-99:1. The contained two pesticides have the advantages of synergy during compounding and capacity of improving the effect of controlling the health insects; and products such as mosquito coils, insecticide aerosols prepared from the pesticidal composition have the advantages of rapidness for killing the pests and durable pesticide effect, and can ideally control the health pests with resistance to pyrethroid pesticides.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to a hygienic, environment-friendly and efficient insecticidal composition for preventing and controlling hygienic pests. Specifically, it is an insecticidal composition containing perfluthrin and lambda-cypermethrin. Background technique [0002] For a long time, the pesticides used to prevent and control sanitary pests are all pyrethroid agents. The long-term use of a single agent of pyrethroids has greatly increased the resistance of sanitary pests such as cockroaches, hygienic mosquitoes and hygienic flies to pyrethroids. In recent years, there has been a general decrease in the control effect. Therefore, an environmentally friendly and efficient new pesticide variety or pesticide compound variety is needed to delay the emergence of resistance to sanitary pests. Since the price of new pesticides is more expensive than conventional pesticides, using them alone will greatly increase...
