Abstract
The present invention discloses an insecticide composition. The insecticide composition contains chlorfluazuron which accounts for 0.1 to 30 wt% of the composition and pyrethroid which accounts for 0.05 to 50 wt% of the composition in the reference of composition weight, and the composition can also contain other auxiliary agents. The insecticide composition overcomes the disadvantage of the drug resistance of pests, and has the advantages of high efficiency, low toxicity, long effect holding time, etc.
Description
Technical field
The present invention relates to a kind of insecticides, be specifically related to a kind of insecticides that contains fluorine pyridine urea and pyrethroid.
Background technology
Known fluorine pyridine urea is a kind of insecticide of high-efficiency low-toxicity, especially efficient to lepidoptera pest, selectivity is strong, be difficult for producing resistance, to natural enemy and other non-target organism safety, can produce environmental pollution hardly, the insect that other insecticides such as organic phosphor, carbamate, pyrethroid has been produced resistance has good control efficiency, and its shortcoming is to play a role slowly.The advantage of known pyrethroid is to kill off the insect pests rapidly, and shortcoming is that insect easily produces resistance.
But, do not disclose the insecticide of the advantage have fluorine pyridine urea and pyrethroid concurrently in the prior art as yet.
Summary of the invention
Thus, the purpose of this invention is to provide a kind of new insecticide, it has the advantage of above-mentioned fluorine pyridine urea and pyrethroid concurrently, promptly can kill off the insect pests very soon, is difficult for making insect to produce resistance again.
Another object of the present invention provides a kind of dilution of this insecticide.
Insecticides of the present invention contains fluorine pyridine urea and pyrethroid, and wherein the content of fluorine pyridine urea is 0.1～30 weight %, and the content of pyrethroid is 0.05～50 weight %, is benchmark with the gross weight of composition.
Dilution of the present invention contains water and insecticide of the present invention, and wherein the weight ratio of water and insecticide is 1000: 1.
Embodiment
