Embodiment 1

[0035] Weigh 10% epoxycloprid, 10% buprofezin, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.3% xanthan gum, 5% propylene glycol , 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 20% epoxycloprid-buprofezin suspension concentrate.

Embodiment 2

[0037] Weigh 10% epoxycloprid, 10% buprofezin, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.3% xanthan gum, 5% propylene glycol , 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 20% epoxycloprid-buprofezin suspension concentrate.

Embodiment 3

[0039] Weigh 2% epoxycloprid, 40% buprofezin, 6% calcium lignosulfonate, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1% sodium lauryl sulfate, 3 % white carbon black and kaolin are added to 100% by weight. 42% epoxycloprid·buprofezin wettable powder is prepared by mixing the above raw materials, pulverizing by ultra-fine airflow, and mixing.

Abstract

The invention discloses an insecticidal composition containing epoxy worm moiety and buprofezin and the application of the insecticidal composition, the effective active ingredients of the insecticidal composition comprise a first active ingredient epoxy worm moiety and a second active ingredient buprofezin, and the weight ratio of the first active ingredient and the second active ingredient ranges from 1:20 to 10:1, preferably from 1:10 to 5:1. The insecticidal composition can be prepared into agriculture allowed suspending agent, wettable powder agent, water dispersible granule, suspension emulsion, microemulsion and cream formulation. The insecticidal composition provided by the invention is reasonable in component, good in insecticidal effect, the activation and insecticidal effect of which is not the simple addition of each active ingredient, compared with the conventional sole agent, the nsecticidal combination has remarkable insecticidal effect, remarkable synergism, is good in crop safety, meets the safety requirement of agricultural agents, and is provided with remarkable control efficiency to nilaparvatalegen and fruit tree scale insects.

Description

technical field [0001] The invention relates to an insecticidal composition, which is composed of a first active ingredient epoxycloprid and a second active ingredient buprofezin, and belongs to the technical field of compound pesticides. Background technique [0002] Epoxycloprid is a neonicotinoid insecticide, created by Wuhan Engineering University, chemical name: 1-(2,3-epoxypropyl)-N-nitroimidazolidin-2-ylamine, chemical formula C 6 h 10 N 4 o 3 . It has systemic, stomach poisoning and contact killing effects on pests, and has the same insecticidal spectrum and insecticidal effect as imidacloprid, the most sold insecticide in the global market. Its persistence is higher than that of imidacloprid, and its toxicity is lower. Epoxycloprid can be used to control Homoptera pests on crops. As a neonicotinoid insecticide, epoxycloprid has resistance risk during use, and rational mixing with different types of insecticides is of great importance for the full and effective...
