    摘要: 1-Hydroxypyrazole derivatives of the formula (I) ##STR1## where A is ##STR2## n is 0 or 1, R.sup.1, R.sup.2 and R.sup.3 independently of one another are each hydrogen, chlorine, bromine or iodine, R.sup.4 is hydrogen, a straight-chain or branched, open-chain alkyl, alkenyl or alkynyl radical, a cyclic alkyl, alkenyl or alkynyl radical or aryl or aralkyl, and the radicals R.sup.4 which are capable of substitution may furthermore be monosubstituted or polysubstituted by halogen, haloalkyl, haloalkoxy, alkyl, alkoxy, alkoxycarbonyl, --OH, .dbd.O, --COOH or salts of this, --NO.sub.2 or --CN, have a nitrification-inhibiting action. Substances where R.sup.4 is not hydrogen when n is 0 are novel.
