Abstract: The invention provides liquid formulation, which comprises 0.1 to 75% by weight of prochloraz, at least 3% by weight of a nonionic surfactant or surfactant mixture, at least 8.5% by weight of a phenol derivative to prevent crystallization of the prochloraz on storage of the emulsion, said phenol being a compound of formulaR.sup.1 --O--Xin which R.sup.1 is phenyl, substituted by one to three C.sub.1 -C.sub.8 -alkyl, .alpha.-methylbenzyl or .alpha.-methyl-4-methylbenzyl groups, by 4-hydroxyphenylene in the para-position, a C.sub.6 -C.sub.22 -alkyl group in the para-position or by two C.sub.3 -C.sub.12 -alkyl groups in the ortho and para-positions, and X is hydrogen, an alkali metal, an alkaline earth metal or NR.sub.3 in which each R is the same or different and is hydrogen or C.sub.1 -C.sub.8 -alkyl, optionally substituted by hydroxy, and at least 1% by weight of an organic solvent which is only slightly soluble in water and which comprises at least one aromatic hydrocarbon.
