Abstract

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.
