A kind of acaricidal composition containing pyrimethan

Abstract

The invention discloses an acaricidal composition containing pyriminostrobin. The acaricidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from pyriminostrobin; the active ingredient B is selected from any one of the following compounds: bifenazate, hexythiazox, spirodiclofen and fenpyroximate or bromopropylate; the weight ratio of the active ingredient A to the active ingredient B is (1 to 80)-(60 to 1). The composition has synergistic effects on various mites harming agricultural production, conduces to reducing the pesticide consumption, reducing the residual quantities of pesticides on crops and reducing environmental pollution, is safe to human and livestock, has good environmental compatibility and enables the mites not to have pesticide resistance easily.
