Problems solved by technology

Glufosinate-ammonium and propargylflufen are compounded into wettable powder, which consumes a lot of energy during the processing, and the dust is easy to drift and cause cross-contamination. When preparing the spray liquid, the powder is prone to flying, which is harmful to the operator. Residual drug powder pollutes the environment. The compounding of glufosinate-ammonium and propargylflumezide into oil suspension not only requires a large amount of organic solvents, but also has high production costs and great environmental pollution.

Abstract

The invention discloses a suspending agent aid suitable for compounding glufosinate-ammonium with flumioxazin. The suspending agent aid comprises the following components in percentage by mass: 1%-30% of styrylphenol polyoxyethylene ether phosphate, 1%-40% of a polycarboxylate dispersant, 1%-20% of dodecyl dimethyl betaine, 1%-10% of iso-tridecanol polyoxyethylene ether and the balance of water. The auxiliary agent has the advantages of excellent wettability and dispersity, small dosage, low cost and stable dispersing performance. The risks of particle aggregation, particle size increase and the like can be reduced, the stability of the suspending agent is greatly improved, and the problems of layering, precipitation and paste formation are avoided.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a high-efficiency adjuvant for a compound suspending agent of glufosinate-ammonium and flufenazine. Background technique [0002] Glufosinate-ammonium is a phosphonic acid herbicide that can inhibit glutamine synthetase in the plant nitrogen metabolism pathway, thereby interfering with plant metabolism and causing plant death. Glufosinate-ammonium is an excellent non-selective, broad-spectrum contact herbicide. With the rise of glyphosate resistance and restrictions on the use of paraquat, the sales of glufosinate-ammonium continue to rise, and it has become the second largest genetically modified crop herbicide in the world. [0003] Flurafen propargyl is a cyclic imide herbicide. Flufenoxam is a protoporphyrinogen oxidase inhibitor and a contact-type selective herbicide for controlling broad-leaved weeds in soybeans, cotton, grapes and many other crop fields. T...
