Novel triazolinone intermediates, for novel herbicidal sulphonylaminocarbonyltriazolines having substituents which are bonded via sulphur, of the formula ##STR1## in which n is O, and or 2, and R1' and R2' are as defined herein.

Intermediates for herbicidal sulphonyl-aminocarbonlyltriazolinones

Intermediates for herbicides, the intermediates having the formula ##STR1## in which R is i-propyl, n-butyl, i-buty, s-butyl or cyclopropyl.

Herbicidal substituted triazolinones

Triazolinone intermediates, for herbicidal sulphonylaminocarbonyltriazolines having substituents which are bonded via sulphur, of the formula ##STR1## in which n is 0, and

Intermediates for herbicidal sulphonylaminocarbonyltriazolinones having

Novel herbicides and plant growth regulants of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkylalkyl or cycloalkyl, or represents in each case optionally substituted aralkyl or aryl,

Substituted triazolinone herbicides and plant growth regulators

Intermediates for herbicides, the intermediates having the formulas ##STR1## in which R.sup.1 represents alkyl having 3 to 4 carbon atoms or represents cyclopropyl,

Herbicidally active substituted triazolinones of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, cycloalkyl, cycloalkylalkyl, or represents tetrahydrofuranyl, tetrahydrofuranylalkyl, or represents in each case optionally substituted aralkyl or aryl,

Novel herbicides and plant growth regulants of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkylalkyl or cycloalkyl, or represents in each case optionally substituted aralkyl or aryl,

Herbicidal substituted triazolones of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkylalkyl or cycloalkyl, or represents in each case optionally substituted aralkyl or aryl,

Herbicidal substituted triazolones

Herbicidal substituted 4-amino-5-alkylthio-1,2,4-triazol-3-ones of the formula ##STR1## in which R.sup.1 represents in each case straight-chain or branched alkyl, alkenyl or alkinyl, each of which has up to 4 carbon atoms, and

Herbicidal substituted 4-amino-5-alkylthio-1,2,4-triazol-3-ones

The invention relates to the use of partly known substituted pyrazolin-5-one derivatives of the formula (I) ##STR1## as herbicides and fungicides, new substituted pyrazolin-5-one derivatives and processes for their preparation.

Herbicidal and fungicidal agents based on substituted pyrazolin-5-one

Triazolone derivatives of the formula ##STR1## in which R.sup.1 and R.sup.2 each independently represents alkyl, alkenyl, alkynyl, halogenoalkyl, halogenoalkenyl, halogenoalkynyl, alkoxyalkyl, cycloalkylalkyl, cycloalkyl or represents aralkyl or aryl, which may be substituted

Intermediates for the preparation of triazolone derivatives

Novel herbicides and plant growth regulants of the formula ##STR1## in which R.sup.1 represents hydrogen alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkylalkyl or cycloalkyl, or represents in each case optionally substituted aralkyl or aryl,

3-amino-5-amino-carbonyl-1,2,4-triazoles of the formula ##STR1## are obtained in good yields and in high purity when a chloroformadine hydrochloride of the formula ##STR2## are reacted with an oxamohydrazide of the formula ##STR3## This reaction can be carried out in the presence of an acid acceptor and in the presence of a diluent at temperatures between 0.degree. C. and 150.degree. C.
