The invention relates to the field of pesticides and particularly relates to a herbicidal suspoemulsion. The herbicidal suspoemulsion comprises the following components in parts by weight: 20-40 parts of pretilachlor raw pesticide, 9-10 parts of fenclorim, 10-20 parts of fluroxypyr raw pesticide, 10-40 parts of surface active agent and 20-60 parts of water, wherein the surface active agent is selected from one or mixture of more than two of agricultural emulsifier No. 500, agricultural emulsifier No. 400, agricultural emulsifier JFC, agricultural emulsifier No. 1600, agricultural emulsifier No. 33, agricultural emulsifier No. 600 and agricultural emulsifier No. 700. Compared with pretilachlor missible oil and fluroxypyr missible oil, the preparation adopts water as a solvent, is more environment-friendly to the environment, less prone to causing a fire during a transportation process, safer and low in cost, can improve the effects of controlling in-field weeds, controlling fresh weight and controlling comprehensive fresh weight, and is further safe for in-field crops.
