Abstract

The embodiment of the invention discloses a dispersible oil suspension concentrate taking glyphosate as an effective component and a preparation method thereof, and belongs to the technical field of pesticides. The dispersible oil suspension concentrate taking glyphosate as the effective component is prepared from the following components in percentage by mass: 25-35% of glyphosate, 10-20% of an emulsifier, 1-8% of a dispersing agent, 1-10% of a synergist, and 0.05-2% of a thickening agent, with the balance being a dispersion medium, and the sum being 100%. The dispersible oil suspension concentrate disclosed by the invention is qualified in low-temperature fluidity, dispersion stability and heat storage stability, stable in quality and good in performance; the surface tension is relatively low, the utilization rate of the preparation in use is improved, and the pesticide effect can be better exerted. The dispersible oil suspension concentrate has good control effects on gramineous weeds such as Setaria viridis, Digitaria sanguinalis, Indian goosegrass and Alopecurus aequalis, raw materials are easily available, the preparation process is simple and industrial production is easy.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of pesticides, in particular to a dispersible oil suspension containing glyphosate as an active ingredient and a preparation method thereof. Background technique [0002] Glyphosate alias Roundup, chemical name: N-(phosphonic acid methyl) glycine, molecular formula C 3 h 8 NO 5 P, is a non-selective, non-residual herbicide, very effective against perennial root weeds, mainly inhibits enolpyruvyl shikimelin phosphate synthase in plants, thereby inhibiting the conversion of shikime to phenylalanine , tyrosine and tryptophan, protein synthesis is disturbed, leading to plant death. Glyphosate is a systemic herbicide that kills herbicides. It is different from contact-killing pesticides. Systemic absorption has a conduction process. Relatively speaking, the time is relatively slow. Generally, it takes 5 to 7 days to take effect. Weeds will slowly wither in about a month, and can cont...
