To obtain a herbicide composition containing a triazine derivative, capable of exterminating wide variety of weeds at a low rate of application and free from environmental pollution problem.

The herbicide composition contains a triazine derivative of formula (X1 is a 1-4C alkyl or a halogen; (n) is 0-4; plural X1 may be same or different when (n) is ≥2; R1 is a 1-10C alkyl, etc.) and at least one kind of compound selected from phenoxy-type herbicide, benzoic-type herbicide and pyridine-type herbicide as active components. The weight ratio of the compound of formula: the compound selected from phenoxy-type herbicide, benzoic-type herbicide and pyridine-type herbicide is 100:1 to 1:5. The composition is useful for the cultivation of true grasses such as rice, wheat, barley, corn, oat and sorghum and broad-leaved crops such as soybean, cotton, beet, sunflower and rapeseed and for the control of weeds such as bird's-eye, violet, knotgrass, goose-grass, camomile, white dead nettle, red poppy and water foxtail.
