A PROCESS FOR THE MANUFACTURE OF HERBICIDALLY ACTIVE DIURETHANES

摘要

Diurethanes of the general formula are disclosed, in which R1 is alkyl, alkenyl or haloalkyl, and R2 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.
