Description

Insecticidal composition containing flubendiamide and application thereof Technical Field The invention belongs to the field of pesticides, and particularly relates to an insecticidal composition containing flubendiamide and application thereof. Background The flubendiamide and the quinoline pesticide inhibit the electron transfer compound III to prevent cells from utilizing energy and block energy conversion, so that pests are killed. The quick-acting pesticide has good quick-acting property, has double functions of contact killing and stomach toxicity, has no systemic property, can be used for preventing and controlling thrips, whiteflies and lepidoptera pests on crops such as fruit trees, vegetables, tea trees and the like, and has low toxicity to birds and bees. The compound shown in the formula I is (S) -4- (5- (3-chloro-5- (trifluoromethyl) phenyl) -5- (trifluoromethyl) -4, 5-dihydro-isoxazol-3-yl) -2-methyl-N- (2-oxo-2- ((2, 2-trifluoroethyl) amino) ethyl) benzamide, belongs to gamma-aminobutyric acid gated chloride ion channel allosteric modulator compounds, has the characteristics of broad spectrum, high activity, high selectivity and the like, has good biological activity on agricultural pests such as hemiptera, thysanoptera, diptera, lepidoptera and the like, and has the following structural formula: (formula I). Chemical control is a common means for controlling agricultural pests, but long-term use of a single medicament for controlling the agricultural pests can gradually improve the drug resistance of target pests, reduce the drug effect and shorten the life cycle of the compound. The compound is scientifically and reasonably combined, so that the dosage can be reduced, the control effect on target pests is improved, the generation of drug resistance is slowed down, and the service life of the compound is prolonged. Disclosure of Invention Based on the above circumstances, the present invention aims to provide an insecticidal composition containing flubendiamide and a preparation thereof, which are used for controlling agricultural pests, especially thrips, and the insecticidal composition has a synergistic effect, and can reduce the dosage while improving the efficacy. The technical scheme of the invention is as follows: An insecticidal composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is flubendiamide, and the active ingredient B is a compound shown in a formula I: The mass ratio of the active ingredient A to the active ingredient B is 1-30:1-30. Further, the mass ratio of the active ingredient A to the active ingredient B is 1-10:1-10. Further, the mass ratio of the active ingredient A to the active ingredient B is 1-5:1-5. Further, the active ingredient accounts for 1% -50% of the weight of the pesticide composition. Further, the insecticidal composition further comprises an auxiliary agent, wherein the auxiliary agent is selected from one or more of wetting agents, dispersing agents, emulsifying agents, thickening agents, disintegrating agents, antifreezing agents, defoaming agents, solvents, preservatives, stabilizers, binders, synergists and carriers. Further, the insecticidal composition can be prepared into any one of agriculturally acceptable dosage forms. Further, the dosage form comprises a suspending agent, emulsifiable concentrate, water dispersible granules and a seed treatment agent. The insecticidal composition is applied to controlling agricultural pests. Further, the agricultural pest includes lepidoptera, thysanoptera, hemiptera. Further, the agricultural pest is thrips. The invention has the beneficial effects that: 1. The insecticidal composition provided by the invention has obvious synergistic effect and can effectively control target pests. 2. The insecticidal composition provided by the invention can reduce the dosage and the cost of the pesticide while ensuring the efficacy. 3. The insecticidal composition provided by the invention can effectively delay the occurrence of drug resistance of pests.
