Abstract
The invention provides a composition. The composition comprises two active ingredients, the first active ingredient comprises at least one of compounds respectively represented by A-7, A-8 and A-10, and the second active ingredient comprises bifenazate. The composition is used for preventing and controlling agricultural pest mites, and can improve the control effect, reduce the agricultural cost and delay the production of the pesticide resistance of the pest mites.
Description
technical field [0001] The present invention relates to a composition, in particular to an acaricidal composition. Background technique [0002] Agricultural pest mites are one of the most difficult pests to control due to their small size, rapid reproduction, strong adaptability, and easy resistance. Pest mites are important organisms of fruit trees, vegetables, and agricultural and forestry crops. They mainly harm leaves, but also young shoots, flower buds and fruits. After a sharp increase in the number of insect populations, it often causes plant defoliation, growth inhibition or even death. The crops in the affected area are often slightly shorter, and the quality and yield are obviously reduced. [0003] Spirocyclic ether compounds, as shown in the following structural formulas A-7, A-8 and A-10, have the same mechanism of action as spirodiclofen, mainly inhibiting fat synthesis in harmful mites, and have no difference with existing acaricides. Cross-resistance, sui...
