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.
