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 flour, 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 of weight 34g).

[0032] On the other hand, 0.3 parts by weight of deltamethrin was dissolved in vegetable oil to obtain a 0.3 w / v% solution containing deltamethrin.

[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 0.03w / w% deltamethrin.

Embodiment 3

[0049] 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.

[0050] Reference Example 4

[0051] 0.3 parts by weight of deltamethrin 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 tank with a valve, and is injected into the air through the valve under pressurized conditions. Inject 40.0 parts by weight of dimethyl ether into the aerosol can to obtain an insecticide aerosol III, which contains 0.3w / w% of deltamethrin.

Abstract

The invention relates to a tetraflumethrin and deltamethrin-containing composition and application thereof, and provides a pesticide composition for preventing and controlling sanitary pests, such as sanitary mosquitoes, sanitary flies, Blattella germanica and the like. The mass ratio of the tetraflumethrin to the deltamethrin is 1:99-99:1. The two pesticides contained in the composition show obvious synergistic effect when compounded, so the sanitary pest prevention and control effect can be obviously improved; and the pesticide composition has the advantages of quick killing of pests and enduring pesticide effect when used for preparing the products, such as disk-type mosquito coils, insect aerosol and the like, and can very ideally prevent and control the sanitary pests which have resistance against dimethrin 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. In particular an insecticidal composition comprising perfluthrin and deltamethrin. 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 the cost of ...
