Embodiment 1

[0023] Weigh 5% epoxycloprid, 50% rotenone, 3% TERSPERSE2700, 2% diffusing agent NNO, 3% pull open powder BX, 2% K-12, 3% white carbon black, 5% ammonium sulfate, diatomaceous earth Add to 100% by weight. 55% epoxycloprid · rotenone water dispersible granules were prepared by the conventional method for preparing water dispersible granules from the above raw materials, ie mixing, ultra-fine airflow pulverization, mixing and granulation.

Embodiment 2

[0025] Weigh 50% epoxycloprid, 10% rotenone, 3% TERSPERSE4894, 2% TERSPERSE2500, 1% TERSPERSE2425, 0.2% xanthan gum, 3% white carbon black, 5% ethylene glycol, 0.3% benzoic acid, 0.5% Organosilicon defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.) was added to 100% by weight of deionized water. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 60% epoxycloprid-rotenone suspension concentrate.

Embodiment 3

[0027] Weigh 20% epoxycloprid, 2% rotenone, 5% calcium lignosulfonate, 2% pull-off powder BX, 2% K-12, 3% white carbon black, kaolin and add to 100% by weight. The above raw materials were mixed and jet milled to obtain 22% epoxycloprid·rotenone wettable powder.

Abstract

The invention discloses an insecticidal composition which is prepared by compounding cycolxylidin and rotenone. Cycolxylidin and rotenone can be compounded and made into agriculturally-acceptable dosage forms such as missible oil, wettable powder, water dispersion granule, suspension agent, oil suspension agent, ultralow capacity fluid, electrostatic oil, and dry suspension agent. The insecticidal composition can be used to control corresponding insects in agriculture. The cycolxylidin and rotenone work together to generate a synergetic effect, thus the using amount of pesticide is reduced, so the insecticidal composition is safer and more environment-friendly.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to an insecticidal composition, in particular to an insecticidal composition containing epoxycloprid and rotenone. 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 promotion of epoxycloprid and prolongi...
