A mixed composition for weeding useful as a herbicide which is effective against a wide spectrum of weeds, is highly active, has excellent residual activity, and is highly safe for useful plants. It is characterized by containing as an active ingredient a combination of (A) a compound selected among a difluoromethanesulfonylanilide compound represented by the general formula (I): (wherein Ris hydrogen, Calkyl, or Calkoxyalkyl) and salts of the compound and (B) at least one member selected among herbicidal aromatic-ring-containing compounds, e.g., indanofan, and herbicidal nitrogenous heterocyclic compounds, e.g., TH-547, nicosulfuron, Flutiacet-methyl, and atrazine.

Composition for weeding

A pyridone derivative represented by Formula [1] or an agriculturally acceptable salt thereof: wherein Ris a Calkyl group, a Calkenyl group, a Calkynyl group, or the like; Rand Rare each independently a hydrogen atom, a nitro group, a cyano group, or the like; and A is a group represented by Formula A-1, Formula A-2, Formula A-3, Formula A-4, or Formula A-5:  The compounds represented by general formula [1] control various weeds growing in upland fields, orchards, paddy fields, and non-crop lands while showing high safety to useful plants and crops.
