摘要：
Novel herbicidal and plant-growth regulating pyrazoles of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl or halogenoalkyl,R.sup.2 represents nitro or cyano,R.sup.3 represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkinyl, optionally substituted cycloalkyl, optionally substituted cycloalkylalkyl, optionally substituted aralkyl or optionally substituted aryl,Ar represents phenyl which is substituted twice or more, or optionally substituted pyridyl, andY represents O, S, SO or SO.sub.2.Several intermediates therefor are also new.
