Abstract
The invention provides an anti-mite composition which comprises two active ingredients. The first active ingredient comprises at least one of compounds selected from A-7, A-8 and A-9; and the second active ingredient comprises at least one selected from pyridaben, fenazaquin, fenpyroximate, pyrimidifen and tebufenpyrad. The anti-mite composition provided by the invention can achieve effects of improving the control effect, reducing agricultural cost and delaying pest resistance to insecticides.
Description
technical field [0001] The present invention relates to an insecticidal 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 derivatives, as shown in the following structural formulas A-7, A-8 and A-10, have the same mechanism of action as spirodiclofen, which mainly inhibits the fat synthesis in harmful mites, and is comparable to existing acaricides. No c...
