Abstract

The invention relates to a pesticide composition comprising synergistically effective dose of highly performance cypermethrin and Hexaflumuron by a preferred weight ratio of 1:1-9:1, more preferably 7:3-8:2. The pesticide composition can be used for controlling common house-flies and Blattidae.

Description

The composition pesticide that contains beta-cypermethrin and fluorine bell urea
Technical field
The present invention relates to a kind of synergetic pesticide composition, particularly relate to a kind of synergetic pesticide composition that comprises beta-cypermethrin and fluorine bell urea.
Background technology
Beta-cypermethrin (alphamethrin) is a kind of pyrethroid insecticides of efficient, wide spectrum.This medicine is the neural axon conduction depressant drug, belongs to never poison, and effect has the better prevention effect to the various pests on wheat, cotton, vegetables, fruit, the Soybean and Other Crops rapidly, and some insect is also had ovicidal action.The beta-cypermethrin synthesis technique is simple, and use cost is lower, therefore is widely used in agricultural insect management.But beta-cypermethrin also has very significant disadvantages, and it is shorter that is exactly the lasting period, in actual applications because the medication frequency is higher, causes pest resistance to insecticide to produce, and drug effect descends.
Fluorine bell urea (hexafluron) is a kind of novel process for preparation of benzoylurea compounds, and its main mechanism of action is to suppress chitin to synthesize, and the obstruction insect normally casts off a skin and be abnormal.This medical instrument has very high larva and ovicidal activity extremely, and adult is had sterile effect, hinders the growth of ovum.This medicine has action of contace poison concurrently based on stomach poison function, and the power of knocking down is strong, and effect rapidly.It is mainly used in Lepidoptera on the crops such as control cotton, vegetables, fruit tree and coleoptera, Homoptera, Diptera pest.
The applicant is through discovering in a large number, and beta-cypermethrin and fluorine bell urea are used with has unforeseeable control efficiency to preventing and treating sanitary insect pest such as housefly and blattaria, and its synergistic effect is fairly obvious.And, the two use with to sanitary insect pests such as control housefly and blattaria have efficiently, quick-acting is good, the lasting period is long, delay pesticide resistance, environmentally safe etc. characteristics, so is that extraordinary sanitary insect pest is prevented and treated medicament.In addition, the applicant finds by retrieval, still do not have relevant beta-cypermethrin and fluorine bell urea to be mixed at present both at home and abroad and prevent and treat the play-by-play of sanitary insect pest, its relevant report only is to prevent and treat eliminating fish parasites at use fluorine bell urea described in the Chinese patent application 00113613.5 and chlorine cyanogen polyester, but because the active component of itself and the used composition pesticide of the application, controlling object, mixed ratio etc. are all inequality, and it does not provide any synergism test data that are mixed yet.Based on above-mentioned discovery, the applicant has finished the present invention.
Summary of the invention
The object of the present invention is to provide a kind of mixed ratio reasonable, control efficiency is good, the synergetic pesticide composition that drug cost is low.
Another object of the present invention is to provide by formulations such as the formulated missible oil of this composition pesticide, microemulsion, wetting powder, water dispersible granules.
