Compounds exhibiting sufficient herbicidal activity at a low dose of application when they are applied to the soil and plants, and agrochemical compositions in which they are used, in particular herbicides, are described. The compounds are triazine derivatives represented by the following formula 1, or their salts. Herbicides containing them are described. In the formula, R represents a hydrogen atom; C-C1-6 group; C-Salkenyl group, etc., R represents a C-C1-6 alkyl group, etc., Y and Z represent an oxygen atom or a sulfur atom, and A represents a 5- or 6-membered cyclic group that may contain a nitrogen atom , an oxygen atom or a sulfur atom. |
