Abstract

The invention discloses a pesticidal composition comprising the active components including spirotetramat and (B) which is any one of abamectin or emamectin benzoate. The mass ratio of the spirotetramat to B is 100:1-1:40. By combining the spirotetramat and the abamectin or the emamectin benzoate, the composition has obvious synergistic effect and is conductive to retarding or overcoming the drugresistance of pests. The composition of the invention can be used for controlling diverse pests on agricultural crops and is especially suitable for controlling the pests such as aphids, whiteflies, thrips, plant lice and the like.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to a composition containing spirotetramat as an active ingredient. Background technique [0002] Spirotetramat: The common name in English is spirotetramat, which is a tetronic acid insecticide. Spirotetramat has unique action characteristics, it can move up and down in the whole plant, reach the leaves and bark, so as to control pests such as lettuce 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 produce resistance, and the cost of control is high. [0003] Abamectin: English common name Abamectin. Abamectin has contact killing and stomach poisoning effects on insects and mites, and has weak fumigation effect, without systemic effect. Ho...
