Zusammenfassung:Benzimidazolyl derivatives of formula wherein Y represents:- an optionally substituted alkyl, alkenyl or alkynyl group; or an optionally substituted cycloalkyl group; or a group -SR, -OR, halogen, aryl or aralkyl; or 2 groups Y form a fused phenyl ring; R represents a group -OH, -NR R or -XM; A represents a group -SO2NR R ; Y represents an optionally substituted alkyl, alkenyl or alkynyl group; or an optionally substituted cycloalkyl group; or a group such as -SR, -OR, halogen, aryl, aralkyl, -O-aryl or -NR R ; n represents one or two; m represents an integer from 1 to 4; R represents an optionally substituted alkyl group; or an optionally substituted cycloalkyl group; R and R represent independently a group such as hydrogen, R, aryl or aralkyl; X represents oxygen or sulphur; M represents an optionally substituted alkyl group; or an optionally substituted cycloalkyl group; or an aryl, aralkyl, alkenyl, alkynyl, or an imine group; agriculturally acceptable salts thereof; the herbicidal compositions comprising these compounds and their application to crop protection is described.
