PURPOSE:To provide a herbicide composition containing a pyrazolesulfonylurea derivative in combination with 3,7-dichloro-8-quinolinecarboxylic acid, exhibiting synergistic herbicidal effect and capable of controlling cockspur-grass and various weeds from annual weed to perennial weeds at a low rate of application. CONSTITUTION:To objective herbicide composition contains a pyrazolesulfonylurea derivative of formula (A is lower alkyl; B is H, lower alkyl, halogen or lower alkoxy; R is lower alkyl; X and Y are lower alkyl or lower alkoxy; Z is CH or N) and 3,7-dichloro-8-quinolinecarboxylic acid. The amount of the compound of formula is preferably 0.001-50 pts. wt., especially 0.001-10 pts. wt. based on 1 pt. wt. of the 3,7-dichloro-8- quinolinecarboxylic acid. |
