PURPOSE:To prepare a herbicidal composition exhibiting excellent synergistic effect for the selective killing of wide variety of weeds especially in corn field at a low rate of application, by using an N-phenyltetrahydrophthalimide derivative and an S-triazine derivative as active components. CONSTITUTION:(A) 1pt.wt. of an N-phenyltetrahydrophthalimide derivative of formula I [R is lower alkyl, cycloalkyl or halo (lower alkyl)] which is a novel compound having herbicidal effect, is mixed with (B) 0.2-50pts.wt. of atrazine [the S-triazine derivative of formula II (X is H or cyano)] known as a herbicide for corn field, and the mixture used as an active component of the titled composition. The mixture is further incorporated with a carrier or adjuvant, prepared in the form of wettable powder, emulsifiable concentrate, granules, suspension, etc., optionally diluted with water, and applied by foliar treatment or soil treatment at a rate of 1.5-25g of the active component per 1 are. |
