Abstract

The invention relates to a mite-killing composition containing pyrimidifen and pyridaben. An active ingredient is formed by compounding pyrimidifen and pyridaben in a binary manner, wherein the mass ratio of the pyrimidifen to the pyridaben is (1-40):(40-1). The total mass of the active ingredients of the pyrimidifen and the pyridaben in a preparation accounts for 1%-80% of the mass of the whole preparation, and the balance is an auxiliary ingredient which is allowable and acceptable in pesticides. The mite-killing composition can be prepared into forms such as missible oil, suspending agent, wettable powder, water dispersible granules, emulsion in water and microemulsion. The mite-killing composition can be used for preventing tetranychid mites and rust mites on oranges, apples, pears, hawthorns, cottons, tobaccos, tea leaves, vegetables, ornamental plants and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an acaricidal composition containing pyrimaben and pyridaben. Background technique [0002] Pyrimidin is an acaricide with a pyrimidine structure, developed and produced by Sankyo Chemical Co., Ltd., Japan. It is effective for the whole growth period of mites, and can control harmful mites such as spider mites and rust mites. It has excellent quick-acting and long-lasting effects , can control spider mites on crops such as apples, pears, vegetables and tea, and spider mites and rust mites on citrus. The chemical formula of pyrimidin is 5-chloro-N-[2-[4-(2-ethoxyethyl)-2,3-dimethylphenoxy]ethyl]-6-ethyl=pyrimidine-4 - amine, whose chemical structure is . [0003] Pyridaben is a broad-spectrum, contact acaricide, which can be used to control a variety of plant-eating pests. It has a good effect on the whole growth period of mites, that is, eggs, young mites, nymp...
