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, heat 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 additive synergistic effect can be achieved

The invention discloses compounded micro-emulsion with 20% fenoxaprop-p-ethyl and cyhalofop-butyl and a method for preparing the compounded micro-emulsion, and relates to the field of technologies for controlling annual weed such as digitaria sanguinalis, moleplant seeds and cyperus iria in direct-sowing rice fields. Every 100 parts of compounded micro-emulsion at least comprise 4 parts of fenoxaprop-p-ethyl, 16 parts of cyhalofop-butyl, 1 part of mefenpyr-diethyl, 6 parts of styrenated phenol polyoxyethylene ether, 3 parts of polyoxyethylene castor oil, 9 parts of calcium dodecylbenzene sulfonate, 25 parts of dimethylbenzene and the balance water. The method includes pumping raw materials into a preparing vessel and mixing, stirring and dissolving the raw materials; sampling and analyzing the raw materials; preparing the compounded micro-emulsion after the raw materials are qualified, allowing the compounded micro-emulsion to stand still and packaging, detecting and warehousing the compounded micro-emulsion. The compounded micro-emulsion and the method have the advantages that the compounded 20% fenoxaprop-p-ethyl and the compounded cyhalofop-butyl are mixed with each other according to a ratio of 1:4 to obtain the compounded micro-emulsion, and accordingly the action ranges can be obviously expanded while the action ranges cannot be obviously expanded by mixed preparations with other ratios.
Description
technical field [0001] The present invention relates to the technical field of prevention and control of annual weeds in direct-seeded paddy fields, such as crabgrass, siphonia, and broken rice sedge, in particular to a compound microemulsion of 20% fenoxaprop-p-ethyl and cyhalofop-ester and its Preparation. Background technique [0002] At present, the existing herbicidal compositions used for the control of annual weeds in direct-seeded paddy fields such as crabgrass, Qianjinzi, and broken rice sedge, for example, Chinese patent "CN 104430460 A" discloses a kind of "pyrazosulfuron-methyl, isosulfuron Oxazone and butachlor compound dispersible oil suspension and its preparation method", according to parts by weight, consists of 2 parts of pyrazosulfuron-methyl, 8 parts of clomazone, 60 parts of butachlor, 2 parts of fatty alcohol polyoxygen Made with vinyl ether, 3 parts styrylphenol ethoxylate, 2 parts xanthan gum, 1 part sodium benzoate, 2 parts silicone, and 20 parts mi...
