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

[0032] 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).

[0033] On the other hand, 0.2 parts by weight of cypermethrin was dissolved in vegetable oil to obtain a 0.2 w / v% solution containing cypermethrin.

[0034] Use a micro-syringe to draw 3.4ml of the above mixed solution and evenly drop it onto 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 0.02w / w% cypermethrin.

Embodiment 3

[0050] Mix 0.35 parts by weight of perfluthrin and 59.65 parts by weight of methanol to prepare an insecticidal composition and an insecticidal solution, put the obtained solution into an aerosol tank 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 insecticidal aerosol II, which contains 0.35w / w% of perflumethrin.

[0051] Reference Example 4

[0052] 0.35 parts by weight of cypermethrin and 59.65 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 is supplied to the aerosol can through the valve under pressurized conditions. Inject 40.0 parts by weight of dimethyl ether to obtain an insecticide aerosol III, which contains 0.35w / w% of cypermethrin.

Abstract

The invention relates to a composition containing tetraflumethrin and cypermethrin and application thereof and provides a pesticidal 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 cypermethrin is 1:99-99:1. When compounded, two pesticides contained in the composition have remarkable mutual synergistic effect and can remarkably improving the prevention and control effect on the sanitary pests. When used for preparing products such as coil-type insect-killing mosquito incenses, pesticidal aerosols and the like, the pesticidal composition has the advantages of rapid killing of the pests and durable pesticide effect and can ideally prevent and control the sanitary pests which are resistant to dimethrin medicaments.

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 it is an insecticidal composition containing perfluthrin and 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 the co...
