Fenoxycarb has stomach toxicity and action of contace poison, and has insect growth regulator, IGR effect, desinsection wide spectrum; But its insecticidal action right and wrong are neuropathic, show as various insects is had to strong juvenile hormone activity, ovicidal be can cause, the metamorphosis in adult stage and casting off a skin of larval phase suppressed, cause after larva friend or pupa time dead, the lasting period is long, harmless to beneficial organism.Can be used for preventing and treating sanitary insect pest, forestry pest, storage pest and agricultural pests.
But its action effect is also very single, after large-scale application, resistance risk is also very high.
Summary of the invention
The object of the present invention is to provide a kind of aqueous emulsion and application thereof that has beta-cypermethrin and fenoxycarb, said composition active ingredient is beta-cypermethrin and fenoxycarb, wherein the weight ratio of beta-cypermethrin and fenoxycarb is, beta-cypermethrin: fenoxycarb=1:1-1:5, this compounded combination has effectively resisted the problem that pest resistance produces, farthest alleviated the problem of current pest resistance to insecticide, thereby reduced the consumption of agricultural chemicals, also alleviated the impact for environment, the trend that meets future society environmental protection, composition of the present invention is received best crop protection effect.
Technical scheme of the present invention is:
An aqueous emulsion for beta-cypermethrin and fenoxycarb, active ingredient is beta-cypermethrin and fenoxycarb, wherein the weight ratio of beta-cypermethrin and fenoxycarb is, beta-cypermethrin: fenoxycarb=1:1-1:5.
As preferably, the weight ratio of beta-cypermethrin and fenoxycarb is, beta-cypermethrin: fenoxycarb=1:2-1:3.
The aqueous emulsion of beta-cypermethrin of the present invention and fenoxycarb, it consists of following component by weight percentage:
