Abstract

The invention discloses an insect-destroying composition comprising the effective components of screw worm ethyl and buprofezin, wherein the mass ratio of the screw worm ethyl and the buprofezin is 40:1-1:80. The screw worm ethyl and the buprofezin are compounded, have an obvious synergistic action, can lower the use quantity of the effective components, reduce the application frequency and are beneficial to delaying the generation of the drug resistance of pests. The composition can be used for preventing and treating various pests in agricultural and horticultural crops and is especially suitable for preventing and treating plant hoppers, leafhoppers, whiteflies and scale insects.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an insecticidal composition containing spirotetramat, and the application of the composition in the control of agricultural pests. Background technique [0002] Spirotetramat (Spirotetramat) is a tetronic acid insecticide. Spirotetramat has two-way systemic conduction properties, and can move up and down in the whole plant to 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 make pests resistant, and the cost of control is relatively high. [0003] Buprofezin is a new type of selective insecticide that inhibits the growth and development of insects. The mechanism of action is to...
