摘要:
1-Aryl-5-alkoximinoalkylamino-pyrazoles of the formula ##STR1## in which R represents cyano or nitro, or represents an optionally substituted heterocyclic radical,R.sup.1 represents hydrogen or alkyl,R.sup.2 represents hydrogen or alkyl, or represents optionally substituted aryl,R.sup.3 represents hydrogen, alkyl or alkenyl, or represents in each case optionally substituted aralkyl or aryl andAr represents optionally substituted phenyl or pyridyl,are active as herbicides and plant growth regulants.
