Glyphosate isopropylammonium and glufosinate-ammonium compounded aqua and preparation method thereof

Abstract

The invention discloses a glyphosate isopropylammonium and glufosinate-ammonium compounded aqua and a preparation method thereof, and relates to the technical field of bare place weed control. The aqua is prepared from 41 parts of glyphosate isopropylammonium, 5 parts of glufosinate-ammonium, 15 parts of a surfactant 8108 (alkyl polyglucoside) and 39 parts of water. The method comprises the following steps: adding glyphosate isopropylammonium, glufosinate-ammonium, the surfactant 8108 (alkyl polyglucoside) and water into a reaction kettle, stirring and mixing until the above raw materials uniformity, sampling the obtained solution, analyzing the content of the solution, filtering after the analysis result is qualified, packaging the obtained product, and warehousing to obtain the aqua. The 46% glyphosate isopropylammonium and glufosinate-ammonium compounded aqua obtained by mixing according to a ratio of 41:5 has obvious synergistic effects, and preparations with other ratios cannot realize obvious synergistic effects.

Description

technical field [0001] The invention relates to the technical field of non-cultivated land weed control, in particular to a compound water agent of glyphosate isopropylamine salt and glufosinate-ammonium and a preparation method thereof. Background technique [0002] At present, the existing herbicidal composition for the control of weeds in non-cultivated land, for example, the Chinese patent "CN104823087A" discloses a "herbicidal composition containing trifenamide and glyphosate isopropylamine salt", in which the effective activity The ingredients are trifenamide and glyphosate isopropylamine salt, and the ratio of the two is 10:1~1:15. Another Chinese patent "CN103975034A" discloses a "herbicidal composition containing glyphosate isopropylamine salt", wherein the effective active ingredients are glyphosate isopropylamine salt, glufosinate-ammonium and penoxsulam. The ratio is 1~50:1~60:1~30. [0003] The inventor has verified through long-term experiments that the above...

Problems solved by technology

For example, the prepared wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and causes precipitation in the sprayer, etc., resulting in uneven spraying and local phytotoxicity of crops. The main reason is that it helps There are different defects in the selection of agents and fillers

[0006] 3), compounding problem, by carrying out toxicity test, thermal storage stability test and co-toxicity coefficient measurement to the above-mentioned several specific proportions disclosed by several herbicidal compositions, it is found that no obvious synergistic effect can be achieved
