Abstract

The invention relates to an acaricide composition and application thereof. The active ingredients in the composition are spirodiclofen and fenbutatin oxide, and the mass portion ratio of the active ingredients is between 5 to 1 and 1 to 50; and the active ingredients are processed into any of dosage forms in pesticide application, and, the preferable dosage forms are wettable powder, water emulsion, emulsifiable solution, micro-emulsion, a water dispersible granule or tablet, and a suspending agent. The acaricide composition has significant synergism on pest mites for controlling the pest mites on plants, and is helpful to reduce the pesticide dosage, reduce the cost, and delay the drug resistance of the pest mites.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to an acaricidal composition with spirodiclofen and fenbutatin as active ingredients, which is used to prevent and control harmful mites in agriculture. Background technique [0002] There are many kinds of harmful mites in my country's agriculture, with mixed feeding habits, wide host range, short life cycle, and strong fecundity. They can occur all year round under greenhouse conditions, and the generations overlap seriously. Pest mites are highly concealed. Once the number of pest mites increases explosively, it will cause great harm to crops. The harm of pest mites leads to stagnation of plant growth, premature senescence of plants, deformed fruits, and seriously reduces yield and quality. [0003] At present, in the control of agricultural pest mites, due to the many generations of pest mites and rapid reproduction, resistance to acaricides is easy to occur. ...
