Herbicidal compsn. for Gramineae and broad-leafed weeds - contg. (3,3')-dimethyl-(4)-methoxy-benzophenone and (S-4)-chloro-benzyl (N,N)-diethyl-thiol-carbamate

摘要

Herbicidal compsn. contains as active components 3,3'-dimethyl-4-methoxybenzophenone (I) and S-4-chlorobenzyl-N,N-diethylthiolcarbamate (II), specifically in ratio 6:4 to 4:6. (I) has excellent herbicidal effect on annual Gramineae weeds and broad leaf weeds from pregermination to one leaf stage and (II) is effective above one leaf stage. Combination of (I) and (II) have synergistic effect even to Gramineae weeds and broad leaf weeds with developed growth.
