m-Cyanoalkoxy-phenylureas having herbicidal activity

Abstract

The m-Cyanoalkoxy-phenylureas of the formula I ##STR1## wherein X is hydrogen or halogen, Y--O is a preferably branched-chain cyanoalkoxy group, and --NR.sub.1 R.sub.2 is a primary, secondary or heterocyclic amino group, exhibit surprisingly good herbicidal activity against mono- and dicotyledonous plants, with a selective action in crops of maize, cereals, cotton and soya bean, and in the case of some of these compounds also in rape crops.

Dependencies are inferred from the claim text.
