Abstract: A method of combating insects and acarids which comprises applying to such insects, acarids or a habitat thereof, an insecticidally or acaricidally effective amount of a 5-amino-1-aryl-pyrazole of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl or halogenoalkyl,R.sup.2 represents trifluoromethyl,R.sup.3 represents hydrogen, alkyl or alkenyl,R.sup.4 represents hydrogen, alkyl, alkenyl, alkinyl or a ##STR2## radical, and Ar represents in each case optionally substituted phenyl or pyridyl, where X represents oxygen or sulphur, and R.sup.5 denotes alkyl or halogenoalkyl.Some of the compounds are new.

Abstract: A 1-aryl-pyrazole of the formula ##STR1## 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 ##STR2## and R.sup.1, R.sup.2 and R.sup.3 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.
