Flucarbazone-sodium and isoproturon compound suspending agent and preparation method thereof

Abstract

The invention provides a flucarbazone-sodium and isoproturon compound suspending agent and a preparation method thereof, and relates to the technical field of prevention and control of annual weeds in wheat fields. According to the present invention, 100 parts of the flucarbazone-sodium and isoproturon compound suspending agent is at least prepared from 4 parts of flucarbazone-sodium, 48 parts of isoproturon, 3 parts of Fatty Alcohol polyoxyethylene ether, 3 parts of styrylphenol polyoxyethylene ether, 0.3 part of xanthan gum, 0.4 part of sodium benzoate, 0.3 part of an anti-foaming agent, and the balance of deionized water; the preparation method comprises: sucking all raw materials into a preparation kettle, carrying out mixing stirring, carrying out primary grinding with a colloid mill, carrying out fine grinding with a sand mill, sampling and analyzing, filtering after achieving the qualified standard, metering, packaging, and warehousing; and the obvious synergistic effect can be provided when the 52% flucarbazone-sodium and isoproturon compound suspending agent is subjected to mixing use according to the ratio of 1:12 while the obvious synergistic effect cannot be achieved with the other preparations being subjected to the mixing use according to a certain ratio.

Description

technical field [0001] The invention relates to the technical field of preventing and controlling annual weeds in wheat fields, in particular to a compound suspending agent of flucarbasulfuron-methyl and isoproturon and a preparation method thereof. Background technique [0002] At present, there are existing herbicidal compositions for controlling annual weeds in wheat fields. For example, Chinese patent CN103461344 A discloses a "herbicidal composition for wheat fields", and the active ingredients are saflufenacil, fenflumezone, and fluroxypyr Oxyacetic acid, the weight percentage of saflufenacil in the composition is 1% to 20%, the weight percentage of mefentrazone in the composition is 1% to 20%, and the weight percentage of fluroxypyr in the composition 1% to 50%, and the rest are pesticide adjuvants. Another Chinese patent CN 104521997 A discloses a "wheat field herbicide composition", the active ingredients are florasulam, aminopyralid (or its salt compounds), phenox...

Problems solved by technology

For example, 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, resulting in uneven spraying

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