Problems solved by technology

There are known reports that glufosinate-ammonium has an ideal control effect on swine blight at 12-24°C. If the temperature is too low, the control effect will be significantly reduced.
[0007] Patent CN105394080A discloses 5% glufosinate-41% glyphosate isopropylamine saline solution, adopts alkyl polyglycoside as surfactant, does not add other additives, so it does not solve the antifreeze problem; patent CN103168798A discloses glufosinate-ammonium The water agent of glufosinate and glufosinate, adding emulsifier and dye, does not solve the antifreeze problem of the composition; patent CN106279243A adopts special water agent additive N-aminoethyl-3-aminopropylmethyldimethoxysilane amber Disodium acid monoacyl sulfonate is used to prepare water formulations, which does not solve the problem of cold resistance and antifreeze; there are other compositions of glufosinate-ammonium and glyphosate in the existing reports, which do not solve the problem of cold resistance and antifreeze

Abstract

The invention relates to a low temperature-resistant glufosinate-glyphosate water aqua. The low temperature-resistant glufosinate-glyphosate water aqua comprises the following components (by weight):5-10% of glufosinate, 30-50% of glyphosate isopropylamine, 1-10% of alkyl glycoside, 1-10% of tallow ammonium polyoxyethylene ether, 1-5% of sorbitol, 1-5% of glucose, 1-5% of polyethylene glycol 400and the balance of water, and totally 100%. The water aqua has very good low temperature resistance, and can be used for controlling weeds such as cyperus rotundus, alopecurus aequalis, cyperus difformis and green bristlegrass.

Description

Technical field: [0001] The invention belongs to the field of pesticide preparations, in particular to a low-temperature-resistant glufosinate-glyphosate aqueous solution. technical background: [0002] Water is the most abundant, cheapest, and most environmentally friendly substance in the world. The active ingredients of pesticides are processed with water as a solvent in the form of water formulations, which are the safest and most environmentally friendly formulations. Pesticides processed in this form are limited by two factors, the solubility and hydrolysis of the pesticide active ingredient in water. Pesticide active ingredients that are easily soluble and soluble in water, and are stable in water, and are most easily processed into water formulations. [0003] The main components of the water agent are pesticide active ingredients and water. Surfactants, additives, antifreeze agents, moisture absorbers, defoamers, viscosifiers, and coloring agents can be added as ne...
