The invention relates to pesticidal compositions containing new substituted pyrazolin-5-ones. The aim of the invention is the provision of new agents with a strong fungicidal and bactericidal action. According to the invention, substituted pyrazolin-5-ones of the general formula (I) in which R 1 is hydrogen or alkyl, R 2 is hydrogen, alkyl, alkenyl, alkynyl, cyanoalkyl, hydroxyalkyl, alkoxyalkyl, hydroxycarbonylalkyl, alkoxycarbonylalkyl are used as the active ingredient in the novel agents or is in each case optionally substituted aralkyl or aryl and R 3 is alkyl, alkenyl, alkynyl, cyanoalkyl, hydroxyalkyl, alkoxyalkyl, hydroxycarbonylalkyl, alkoxycarbonylalkyl, cycloalkyl, cycloalkylalkyl or in each case optionally substituted aralkyl, aryloxyalkyl or arylthioalkyl, but where R 3 is only Methyl or ethyl is when R1 and / or R2 are not simultaneously hydrogen or methyl.
