Abstract

The invention discloses a dispersible oil suspending agent containing triafamone and cyhalofop-butyl. The dispersible oil suspending agent is prepared from 5 to 10% by mass of triafamone, 8 to 10% by mass of cyhalofop-butyl, 3 to 6% by mass of eucalyptus oil, 2 to 4% by mass of gramine, 11 to 13% by mass of an emulsifier, 1 to 2% by mass of a dispersant, 0.5 to 1% by mass of a stabilizer, 0.5 to 1% by mass of a synergist, 10 to 20% by mass of an organic solvent and the balance of methyl oleate. The dispersible oil suspending agent containing triafamone and cyhalofop-butyl has significant synergistic or additive effects. Compared with a single agent, the composition improves the herbicidal effects. Through use of a plant weeding ingredient in the formula, a use amount of pesticide is reduced, a cost is reduced and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a dispersible oil suspension containing flucarbazone-sulam and cyhalofop-methyl. Background technique [0002] Dispersible oil suspension concentrate uses vegetable oil as the dispersion medium, which is friendly to the environment. After spraying with water on the plant surface, it has good adhesion, spreadability and permeability. To achieve synergistic effect, the dosage of active ingredients can be reduced and the cost can be saved. [0003] Flucarbazone-sulam belongs to sulfonamide herbicides and is a broad-spectrum selective herbicide for rice field treatment. After application, it is absorbed through the roots and leaves of plants, and inhibits the onset of acetolactic acid. Broad-leaved weeds Snakehead and Cyperaceae alien sedges have good control effects; cyhalofop-ester belongs to the aryloxyphenoxypropionic acid systemic conduction type herbicide, which...
