Abstract

The invention concerns 1,3-dimethyl-5-fluoro-pyrazole-4-carboxamides of formula (I) in which R stands for a group of formula(II) or (III), in which: R.sup.1 stands for alkyl, cycloalkyl, bicycloalkyl, optionally substituted aryl or optionally substituted aralkyl; m stands for integers from 0 to 3 or two vicinal R.sup.1 groups together stand for an alkylene chain with 3 or 4 carbon atoms; R.sup.2 stands for alkyl, cycloalkyl, bicycloalkyl, optionally substituted aryl or optionally substituted aralkyl; and n stands for integers from 0 to 3 or two vicinal R.sup.2 groups together stand for an alkylene chain with 3 or 4 carbon atoms. The invention further concerns a process for preparing the novel substances, and their use for combating undesirable micro-organisms for plant- and material-protection purposes. ##STR1##
