摘要:
Diurethanes of the general formula ##STR1## are disclosed, in which R.sub.1 is alkyl, alkenyl or haloalkyl, and R.sub.2 is phenyl or cyclohexyl or substituted phenyl or cyclohexyl. These compounds show exceptional selective herbicidal activity in particular in tomato cultures, and are most effective in post-emergence treatment.
