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
The present invention relates to Pesticidal combination, particularly a kind of health that is used to prevent and treat sanitary insect pest, environmental protection, Pesticidal combination efficiently.Be specially the Pesticidal combination that contains tetrafluoro ether chrysanthemum ester and beta-cypermethrin.
Background technology
For a long time, the employed medicament of control sanitary insect pest is the agent of chrysanthemum ester class medicament list, the long-term use of chrysanthemum ester class medicament list agent makes sanitary insect pest such as cockroach, health mosquito and health fly etc. improve greatly the pesticide resistance of chrysanthemum ester class medicament, has occurred the phenomenon that preventive effect generally reduces in recent years.Therefore need a kind of new varieties of pesticides of environment-friendly high-efficiency or the drug-fast generation that the agriculture chemical compounding kind delays sanitary insect pest, because the price of novel pesticide is more expensive than conventional pesticide, use can make the control cost improve greatly separately, and the drug effect that conventional pesticide uses does not separately reach requirement, therefore pass through the composite of two kinds of pesticidal chemicals, can not only improve the control efficiency of control sanitary insect pest so to greatest extent, and economical convenient, greatly reduce the drug-fast generation speed of sanitary insect pest.
Summary of the invention
The technical problem to be solved in the present invention is, defective at the prior art existence, the Pesticidal combination of a kind of tetrafluoro ether chrysanthemum ester and beta-cypermethrin is proposed, kind performance obvious synergistic effect after the combination, reduce the drug-fast generation of sanitary insect pest greatly, have the characteristics of low toxicity, safety, efficient, economy, environmental protection.
