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. 

The present invention is to provide an oxopyrazine derivative having an excellent herbicidal activity and besides exhibiting high safety for useful crops and the like, or a salt thereof, and a herbicide containing the same. The present invention relates to an oxopyrazine derivative represented by formula [I]: wherein Xrepresents an oxygen atom or a sulfur atom; Xrepresents CH or N(O); m represents an integer of 0 or 1; Rrepresents a hydrogen atom, a C-Calkyl group and the like; Rrepresents a halogen atom, a cyano group and the like; Ris a hydroxyl group, a halogen atom and the like; Arepresents C(RR); Arepresents C(RR) or C&#x2550;O; Arepresents C(RR); Rto Rrepresent a hydrogen atom or an alkyl group,
