Employment of N-(butoxymethyl)-2-chloro-2',6'-diethyl acetanilide in combination with at least one .alpha.-(.beta.-naphthoxy)-propionic acid derivative as active ingredients provides an excellent herbicidal composition effective on a variety of weeds.

Herbicidal composition

2,4-Dichloro-3'-(.beta.-chloroethoxy)-4'-nitrodiphenyl ether is prepared by condensing 2,3',4-trichloro-4'-nitrodiphenyl ether with ethyleneglycol in the presence of an acid-binding agent and then chlorinating the hydroxyethoxy group of the resulting condensate. This compound posesses an excellent herbicidal activity to a wide variety of undesirable weeds with an extremely low phyto-toxicity to useful crops.
