A 1-aryl-pyrazole of the formula <IMAGE> in which R represents cyano or nitro, Ar represents in each case optionally substituted phenyl or pyridyl, X represents an azido group, or represents the radical <IMAGE> and R1, R2 and R3 each independently represents alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxy, alkoxyalkyl, cycloalkyl or cycloalkyloxy, or represents in each case optionally substituted aryl, aryloxy, aralkyl or aralkyloxy, but wherein, in the case where R represents cyano and X simultaneously represents an azido group, Ar does not represent unsubstituted phenyl and does not represent 5-nitro-2-pyridyl. The compounds exhibit herbicidal and plant growth-regulating activity. |
