Abstract: Use of imidazole derivs. of formula (I) and their acid addn. salts (if R = H) as nitrification inhibitors is new: R = H, hydroxymethyl or 2-10C acyl; R , R = 1-12C alkyl, 3-6C cycloalkyl or halogen; provided that both are not halogen. Also claimed are mixts. of fertilisers contg.: (A) a mineral fertiliser; and (B) 0.01-1 wt.% (I).

Abstract: Pyrazol derivatives having general formula (I) are disclosed, as well as their use as nitrification inhibitors. In said formula (I): residues R , R , R and R may be substituted once or twice by halogen and/or hydroxyl; the residues R , R and R stand for halogen, nitro, hydrogen, C1-C20-alkyl, C3-C8-cycloalkyl, C5-C20-aryl or alkyl aryl; and R may stand for (a) a residue R of the formula (II), in which R and R stand for hydrogen, C1-C20-alkyl optionally substituted once or twice by halogen and/or hydroxyl, a carboxyl group, a carboxymethyl group or a functional derivative of both latter groups, and R stands for a carboxyl residue or a carboxy-(C1-C3-alkyl) residue or for a functional derivative of said groups, or R may stand for (b) a residue R having the formula (III), in which R and R stand for hydrogen, C1-C20-alkyl, C2-C8-cycloalkyl, C5-C20-aryl or alkyl aryl, these residues being optionally substituted once or twice by halogen, and R stands for hydrogen or a poly-(C2-C4-alkylene oxide) residue whose terminal hydroxyl group may be etherified with an aliphatic C1-C10 alcohol or esterified with a C1-C10 carboxylic acid.

Abstract: 1-Hydroxypyrazole derivatives of the formula (I) (I) where A is n is 0 or 1, R1, R2 and R3 independently of one another are each hydrogen, chlorine, bromine or iodine, R4 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 R4 which are capable of substitution may furthermore be monosubstituted or polysubstituted by halogen, haloalkyl, haloalkoxy, alkyl, alkoxy, alkoxycarbonyl, -OH, =O, -COOH or salts of this, -NO2 or -CN, have a nitrification-inhibiting action. Substances where R4 is not hydrogen when n is 0 are novel.
