The composition can be prepared into water dispersible granule, suspending agent, oil dispersion suspending agent, wettable powder, missible oil, and emulsion in water or micro-emulsion. The invention is reasonable in component, good in acaricidal effect and low in pharmacy cost and has obvious synergy function, the activity and acaricidal effect thereof are not caused by simply mixing the components, the quick-acting property is high, the effective period is long, the resistance forming is slowed down, the safety to crop is high and the safety demand of pesticide preparation is met. The invention has better control efficiency of red spider to citrus, apple tree and cotton.
Description
Technical field
The present invention relates to a kind of miticide composition, particularly a kind of miticide composition that contains second mite azoles and pyridaben that is used to prevent and treat crop evil mites such as cotton, oranges and tangerines, apple belongs to technical field of compounded pesticide.
Background technology
Second mite azoles is the miticide of a kind of brand-new tool special construction of SUMITOMO CHEMICAL KCC research and development, English common name: etoxazole, chemical molecular formula C

20S.Pyridaben is the wide spectrum miticide, and absorption in not having all has obvious control efficiency to planting property of food such as tetranychid, Panonychus citri evil mite, and to ovum, if mite, become mite all effective, also effective to the mobile phase of one-tenth mite.Also can prevent and treat blister mite.Be applicable to crops such as citrus, apple, cotton, vegetables.
At present, the pesticidal preparations that with second mite azoles is effective ingredient is based on 110 grams per liter suspending agents, and in actual use, effective to ovum and young mite, quick-acting is poor, but lasting effect is good, the use cost height; Pyridaben quick-acting is good, to young mite with become, if mite preventive effect height, in use exist the risk that resistance risk increases gradually, the defective that the lasting period is short.The inventor is unexpected to be found second mite azoles and pyridaben be mixed to use to improve its quick-acting, and the good lasting period is arranged again, and significantly synergy, the reduction drug cost, and the generation that slows down pest resistance is to the safety of crop.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, miticidal effect is good, and drug cost is low, the miticide composition that contains second mite azoles and pyridaben that is difficult for developing immunity to drugs.
Another object of the present invention is to provide the miticide composition that contains second mite azoles and pyridaben preparation formulation.
In order to overcome the defective of existing unitary agent, technical scheme of the present invention is to solve like this:
Contain the miticide composition of second mite azoles and pyridaben, comprising:
