Insecticidal composition containing clothianidin and cyromazine and application of composition

Abstract

The invention discloses an insecticidal composition containing clothianidin and cyromazine and application of the composition. The effective active ingredients comprise the first active ingredient clothianidin and the second active ingredient cyromazine, the weight ratio of the first active ingredient to the second active ingredient ranges from 1:50 to 50:1, and the sum of the content of the first active ingredient and the content of the second active ingredient accounts for 1%-80% of the total weight of the composition. The insecticidal composition can be prepared into missible oil, a suspending agent, wettable powder, water dispersible granules, an emulsion in water, microemulsion, a microcapsule preparation, granules and a water-based preparation which are permissible in agriculture. The insecticidal composition is reasonable in component and good in effect on liriomyza and bactrocera dorsalis, and the insecticidal effect of the insecticidal composition is not simple superposition of activity of the ingredients. Compared with an existing single preparation, not only is the significant insecticidal effect achieved, but also a significant synergistic effect is achieved, the dosage is reduced, and the crop safety is good.

Description

technical field [0001] The invention relates to an insecticidal composition containing clothianidin and cyromazine and its application. The composition is composed of the first active ingredient clothianidin, the second active ingredient cyromazine and an auxiliary agent, and belongs to the compound pesticide technology field. Background technique [0002] Clothianidin, whose English name is clothianidin, has a chemical name of (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-2-nitroguanidine. It is a new type of high-efficiency, safe and highly selective insecticide. Its mechanism of action is to bind to the nicotinic acetylcholine receptor located in the post-nerve synapse. Has contact, stomach poisoning and systemic activity. It is mainly used in rice, vegetables, fruit trees and other crops to control aphids, leafhoppers, thrips, planthoppers and other insecticides of Hemiptera, Coleoptera, Diptera and some Lepidoptera pests. [0003] Cyromazine, the English name is...
