Embodiment 1

[0020] Embodiment 1: A kind of chlorpyrrole glyphosate dispersible oil suspension concentrate is made up of the component of following percentage by weight: fluroxypyr 3%, glyphosate 30%, surfactant 15%, white carbon black 1.5% , methyl oleate and / or oil suspension 50.5%; Among them, glyphosate, fluroxyfen, surfactant and white carbon black are mixed and cut and sanded below 65°C to form micron-sized particles degree, add methyl oleate and stir to form a homogeneous oil suspension.

Embodiment 2

[0021] Embodiment 2: a kind of clofenac glyphosate dispersible oil suspension concentrate, is made up of the component of following percentage by weight: fluroxypyr 2%, glyphosate 35%, surfactant 18%, white carbon black 2 %, methyl oleate / or oil suspension 43%; among them, glyphosate, fluroxyfen, surfactant and white carbon black are mixed and cut and sanded below 65°C to form micron-sized particles degree, add methyl oleate and stir to form a homogeneous oil suspension.

Embodiment 3

[0022] Embodiment 3: a kind of chlorpyrrole glyphosate dispersible oil suspension concentrate, is made up of the component of following percentage by weight: fluroxypyr 2%, glyphosate 28%, surfactant 14%, white carbon black 1.5% %, methyl oleate / or oil suspension 54.5%; among them, glyphosate, fluroxyfen, surfactant and white carbon black are mixed under 65°C by shearing and sand milling to form micron-sized particles degree, add methyl oleate and stir to form a homogeneous oil suspension.

Abstract

The invention discloses a fluroxypyr-glyphosate dispersible oil suspending agent which is composed of, by weight, 1.5-3.8% of fluroxypyr, 25-40% of glyphosate, 14-25% of a surfactant, 1-2.5% of white carbon black and 30-60% of methyl oleate, wherein the glyphosate, the fluroxypyr, the surfactant and the white carbon black are mixed, and the mixture is sheared and sand-ground to obtain the homogeneous-phase oil suspending agent in micron scale. In the invention, the methyl oleate and the excellent surfactant are employed as carriers so that the dispersible oil suspending agent is spread on surface of weed plants, thereby fully achieving herbicidal function of the glyphosate and effectively inhibiting photosynthesis of the weed. The dispersible oil suspending agent can quickly kill the weeds, increases herbicidal speed from about 15 days to about 7 days, can effectively improve agricultural work efficiency, reduces usage quantity of the glyphosate in unit area by more than a half, effectively reduces herbicidal cost and is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a dispersible oil suspension concentrate of glyphosate. Background technique [0002] Now the dosage form of glyphosate is generally glyphosate isopropyl ammonium salt, ammonium salt, sodium salt, potassium salt solution and glyphosate soluble powder, soluble granule, because these single doses of glyphosate have been used for a long time In recent years, both foreign and domestic weeds have developed great resistance to a single dose of glyphosate, so the weeding effect is not good, and the dosage of farmers has doubled. Cause soil compaction, crop yield decline, and have an impact on the environment. Contents of the invention [0003] Aiming at the problems of large dosage and gradual deterioration of herbicidal effect in the existing herbicides, the present invention adopts a dispersible oil suspension formulation compounded with glyphosate and fluroxypyr to reduce the d...
