Abstract

The invention discloses a suspending agent containing a saflufenacil composition. The suspending agent comprises 1-55 parts of saflufenacil and the saflufenacil composition, 1-8 parts of a wetting agent, 2-6 parts of a dispersing agent, 0.5-5 parts of a stabilizer, 2-10 parts of an anti-freezing agent, 0.1-0.6 part of a preservative, 1-10 parts of a thickening agent, 0.1-0.8 part of a defoaming agent and the balance of water. The saflufenacil and the composition of the saflufenacil refer to saflufenacil and one or more of mesotrione, pinoxaden, clodinafop-propargyl, fluoroglycofen-ethyl, amidosulfuron-methyl, pyriminobac-methyl and pyraflufen-ethyl; aiming at saflufenacil, the stabilizer can improve the stability of preparations with different crystal forms and reduce the particle size change range of saflufenacil; the stabilizer is prepared from the following components in parts by weight: 8-40 parts of branched chain fatty alcohol alkoxylation surfactant TERGITOLCA-90, 8-40 parts ofsecondary alkyl sodium sulfonate, 6-20 parts of alkynediol (TL-20), 6-18 parts of n-octyl alcohol, 1-5 parts of modified carboxylic acid copolymer and 3-5 parts of mineral oil FINAVESTAN A50B. The invention also discloses a preparation method of the suspending agent, which comprises the following steps: uniformly mixing, sanding, finally adding the thickening agent, and uniformly stirring. The invention has the advantages of good fluidity, the obvious medicinal effect, simple preparation and the low production cost.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a saflufenacil-containing composition suspending agent and a preparation method thereof. Background technique [0002] Pesticide water suspension concentrate is a new dosage form with a short history of development in pesticide preparations and is being developed and perfected. Many herbicides, fungicides and insecticides can be processed into this dosage form. Because of its advantages of wettable powder, it is called an epoch-making new dosage form. It has developed extremely rapidly at home and abroad, and has partially replaced wettable powder. It is a promising new dosage form. [0003] Saflufenacil is a uracil herbicide newly launched by BASF in 2009, and is called by BASF "the most successful new herbicide developed in more than 20 years" and "represents a new level of control of broad-leaved weeds". This product can be applied to a variety of crops, such as: soybeans, corn, ci...
