Problems solved by technology

[0006] Although the dispersible oil suspension concentrate has the above-mentioned many advantages, the preparation technology requirements of this dosage form are high, and it is difficult to prepare. At present, most of the pesticide products of this dosage form registered in the Ministry of Agriculture are corn and wheat field herbicides, and the technology for pesticide products is not yet available. Mature
After searching, there is no bibliographical report on the compound processing of sulfonicaflor and tonamifen (or flonicamid) into dispersible oil suspension in the prior art, in order to successfully develop the dispersible oil contain...

Abstract

The invention discloses a dispersible oil suspension containing sulfoxaflor. The oil suspension is composed of the following components in percentage by weight: 3 to 50% of a first active component, 3 to 50% of a second active component, 5 to 25% of emulsifier, 2 to 15% of dispersant, 1 to 8% of wetting agent, 1 to 7% of thickening agent, 1 to 5% of anti-freezing agent, 1 to 6% of stabilizing, and the balance being disperse medium; wherein the first active component is sulfoxaflor, and the second active component is tolfenpyrad or sulfoxaflor. The oil suspension is prepared through the following steps: adding an emulsifier, a dispersant, a wetting agent, a stabilizing agent, and a disperse medium into a reactor, mixing, evenly dispersing; adding a thickening agent, an anti-freezing agent, a first active component, and a second active component under a high-speed shearing state, and grinding until the particle size is smaller than 5 [mu]m. The oil suspension has the characteristics of environment-friendliness, good effect, rain scrubbing resistance, long-lasting effect, and safety for crops, and has a very good control effect on aphis citricola, rice plant hopper, tea lesser leafhopper, and cotton aphid.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides and relates to an agricultural insecticidal composition, in particular to a dispersible oil suspension containing sulfoxaflor, the insecticidal active ingredient of which includes the first active ingredient sulfoxaflor and the second active ingredient tonamirad or flonicamid. The invention also relates to the preparation method and application of the dispersible oil suspension. Background technique [0002] Sulfoxaflor, common name in English: sulfoxaflor, chemical name: [1-[6-(trifluoromethyl)pyridin-3-yl]ethyl]methyl(oxygen)-λ4-mercaptocyanamide. Sulfoxaflor is a sulfonylimide insecticide that acts on a unique binding site in the insect choline receptor to exert its insecticidal function. Sulfoxaflor can be absorbed into plants through leaves, stems, and roots, and is suitable for controlling crop pests such as aphids, mirid bugs, whiteflies, planthoppers, and scale insects. As a...
