Disclosed are triazine derivative compounds exhibiting sufficient herbicidal activity at low application dosage when they are applied to soils and foliage, and an agrochemical composition using the same, in particular herbicides.

6-acyl-1,2,4-triazine-3,5-dione derivative and herbicides

Disclosed are compounds exhibiting sufficient herbicidal activity at low application dosage when they are applied to soils and foliage, and an agrochemical composition using the same, in particular herbicides. The compounds are triazine derivatives represented by following Formula 1 or salts thereof, and the herbicides containing them: [Chem. 28] wherein in the formula, Rrepresents a hydrogen atom; a C-Calkyl group; a C-Calkenyl group, etc., Rrepresents a C-Calkyl group, etc., Y and Z represent an oxygen atom or a sulfur atom, and A represents a 5- or 6-membered cyclic group which may contain a nitrogen atom, an oxygen atom, or a sulfur atom. 

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.
