A herbicidal emulsion composition comprising an ethenylamide compound as a herbicidally active component and a dichloroacetamide compound as a phytotoxicity reducing agent. This composition has excellent keeping stability because the phytotoxicity reducing agent of the composition does not decompose and crystals do not separate out even when it is kept for a long time. An amino alcohol and a polar nonaqueous solvent as a solvent are added to the ethenylamide compound and the dichloroacetamide compound to prepare a herbicidal emulsion composition.

Herbicidal emulsion compositions

Ketonitrile derivatives and antibacterial agent and drugs containing the

A process for producing an ethenyl amide compound, which comprises reacting a Schiff base compound having a carbon atom adjacent to a carbon atom constituting an imino group and at least one hydrogen atom on the carbon atom with an acylhalide at a reduced pressure while removing by-produced hydrogen halide by distillation to produce an ethenyl amide compound having an amide bond in the molecule and a double bond between carbons at .alpha.-position and .beta.-position with respect to the nitrogen atom of the amide bond.
