Abstract

The invention provides a glufosinate-ammonium oil suspension agent and a preparation method thereof, and relates to the technical field of pesticides. The glufosinate-ammonium oil suspension agent comprises the following components by mass percentage: 20-40% of glufosinate-ammonium, 10-20% of a surfactant, 0.5-5% of a thickener and the balance of a solvent, wherein the surfactant is a mixture of calcium dodecylbenzene sulfonate and a surfactant A. The invention also provides a preparation method of the glufosinate-ammonium oil suspension agent, and the method comprises the steps as follows: adding glufosinate-ammonium, the surfactant, the thickener and the solvent into a reaction kettle according to the formula ratio, stirring uniformly, grinding with a sand mill and filtering to obtain the glufosinate-ammonium oil suspension agent. The oil suspension agent provided by the invention overcomes the defect that the drug loss is excessive when the other dosage forms such as a water agent and the like are applied, and not only contains glufosinate-ammonium as high as 20% to 40%, but also has high stability, low cost and high pesticide effect, and the preparation method is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a glufosinate-ammonium oil suspension and a preparation method thereof. Background technique [0002] Oil suspension concentrate is a high-dispersion and stable suspension system formed by one or more active ingredients of pesticides (at least one of which is a solid original drug) in a non-aqueous dispersion medium. The development of oil suspension concentrates began in the late 1970s and developed rapidly in the 1980s. Compared with water suspension concentrates, wettable powders, water dispersible granules and other dosage forms, this dosage form has the advantages of good permeability, strong adhesion, etc., and greatly improves the biological activity of the medicine. [0003] Glufosinate ammonium (Glufosinate ammonium), the molecular formula is C 5 h 15 N 2 o 4 P, the molecular weight is 198.1574, and the CAS number is 77182-82-2. Glufosinate-ammonium is an organo...
