Abstract

The invention discloses an oxadiargyl and butachlor aqueous emulsion and a preparation method thereof. The aqueous emulsion comprises the following components in percentage by weight: 1%-40% of oxadiargyl, 1%-60% of butachlor, 1%-40% of solvent, 1%-40% of emulsifying agent, 0.1%-10% of thickening agent, 1%-5% of antifreezing agent, 0.1%-1.0% of defoamer, 0.1-1% of preservative agent and the balance of de-ionized water. The preparation method comprises the following steps: dissolving oxadiargyl in the solvent and adding a butachlor pharmacological agent, the emulsifying agent and the thickening agent, thus obtaining an oil phase; mixing the antifreezing agent with the de-ionized water to obtain a water phase; and under a high shear condition, slowly adding the oil phase into the water phase or adding the water phase into the oil phase, thus obtaining the oxadiargyl and butachlor aqueous emulsion. In the field experiment, the oxadiargyl and butachlor aqueous emulsion can achieve a better effect of preventing weeds in a paddy field. The oxadiargyl and butachlor aqueous emulsion has the advantages of high efficiency, low toxicity, environmental friendliness and safety for human and livestock.

Description

technical field

[0001] The invention relates to an aqueous emulsion of propargyl oxadiazone and butachlor and a preparation method thereof, belonging to the field of pesticides. Background technique

[0002] As people's awareness of environmental protection becomes stronger and more eager for high-efficiency, low-toxicity, low-residue, and environmentally-friendly pesticides, pesticide science and technology workers are working day and night to develop new varieties and new formulations of high-efficiency, low-toxicity, and environmentally friendly pesticides.

[0003] Oxadiazone propargyl is a high-efficiency broad-spectrum rice field herbicide, which has a remarkable effect on annual grasses, sedges, broad-leaved weeds and some perennial weeds, and has good control effect on the vicious weed Cloverleaf. Mainly used for pre-emergence control of broad-leaved weeds such as rice, potato, sunflower, vegetables, sugar beets, orchards, such as velvetleaf, ghost needle grass, Chen...
