Abstract

The invention discloses a pesticidal composition comprising the active components including spirotetramat and pymetrozine, with mass ratio of 40:1-1:80. By combining the spirotetramat and the pymetrozine, the composition has obvious synergistic effect, can reduce the consumption of the active components and is conductive to retarding the drug resistance of pests. The composition of the invention can be used for controlling diverse pests on agricultural and horticultural crops and is especially suitable for controlling the sucking mouthparts pests such as plant hoppers, aphids, thrips, whiteflies and the like.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition whose active ingredients are spirotetramat and pymetrozine, and its application in preventing and controlling agricultural and horticultural crop pests. Background technique [0002] Spirotetramat (Spirotetramat) is a tetronic acid insecticide. Spirotetramat has a unique mechanism of action, which can move up and down in the plant body to reach the leaves and bark, so as to control pests such as raw raisins and cabbage inner leaves and fruit bark. Spirotetramat is highly efficient and broad-spectrum, and can effectively control various piercing-sucking mouthpart pests, such as aphids, thrips, psyllids, mealybugs, whiteflies and scale insects. However, if spirotetramat is used alone, it is easy to make pests resistant, and the cost of control is relatively high. [0003] Pymetrozine, the main mode of action is contact and systemic action. Due to the dif...
