A microbicidal composition is disclosed comprising a) at least one 3-isothiazolone of the formula (I) wherein Y is (C1-C18)alkyl or (C3-C12)cycloalkyl each optionally substituted with one or more of hydroxy, halo, cyano, alkylamino, dialkylamine, arylamino, carboxy, carbalkoxy, alkoxy, aryloxy, alkylthio, arylthio, haloalkoxy, cycloalkylamino, carbamoxy, or isothiazolonyl; an unsubstituted or halo-substituted (C2-C8) alkenyl or alkynyl; a (C7-C10)aralkyl optionally substituted with one or more of halogen, (C1-C4)alkyl or (C1-C4)alkoxy; and an aryl optionally substituted with one or more of halogen, nitro, (C1-C4)alkyl, (C1-C4)alkyl-acylamino, carb(C1-C4)alkoxy or sulfamyl; and R and R is each independently H, halogen or (C1-C4) alkyl; and b) a carbonyl compound comprising (C2-C6) aldehydes, (C7-C10) aromatic aldehydes or acids, (C2-C4) dialdehydes, (C1-C12) acids, (C2-C8) diacids, triacids or tetracids, (C3-C10) alpha , beta unsaturated carbonyls, (C1-C6) haloamides of the formula where R3 = phenyl or (C1-C4)alkyl-substituted phenyl, R2 = (C1-C7)alkyl, (C1-C7)alkoxylalkyl, or (C1-C7)carbalkoxyalkyl, X1, X2, X3 = H or halogen wherein at least one X is halogen; or furfural, dibutylene furfural and maleimides of the formula where R sec is H, (C1-C4) alkyl or aryl; provided that when (b) comprises an aldehyde or dialdehyde the ratio (b):(a) is less than 10:1. The carbonyl compound acts as a stabiliser for the 3-isothiazolone.
