摘要:
Provided is a herbicide composition which comprises a combination in a specific proportion of 2-[(4,6-dimethoxypyrimidin-2-yl)hydroxymethyl]-6-methoxymethyl-N-difluoromethanesulfonylanilide as the component (A) and either one of fifteen kinds of compounds including 4-(2-chlorophenyl)-N-cyclohexyl-N-ethyl-4,5-dihydro-5-oxo-1H-tetrazole-1-carboxamide as the component (B), none of which has been used in combination with the compound as the component (A). By an application of the herbicide composition to a paddy field in a specific dose, an excellent herbicidal effect is obtained against various kinds of weeds growing in paddy fields and the chemical damages thereof to paddy rice is extremely low.
