A synergistic microbicidal composition having two components. The first component is a nonionic surfactant with structure: R.sup.2O(CH.sub.2CH(CH.sub.3)O).sub.3(CH.sub.2CH.sub.2O).sub.5H, where R.sup.2 is a mixture of C.sub.8-C.sub.14 linear alkyl groups. The second component is 2-bromo-2-nitropropane-1,3-diol. The weight ratio of the nonionic surfactant to 2-bromo-2-nitropropane-1,3-diol is from 1:0.08 to 1:0.12 or 1:0.2 to 1:1.8286.
