The invention provides methods and compositions for addressing the problem of microorganism infestations and especially biocorrosion in slurry transporting pipelines. The method comprises treating pipeline fluid (especially plug fluid) with an oxidizing biocide in an amount higher than the oxidant demand of the pipeline and a non-oxidizing biocide in an amount less than 30% of the minimum necessary to sterilize the microbiological organisms. This treatment makes use of the unique characteristics of a slurry pipeline to eliminate microorganisms without harming the pipeline as would be expected by using an oxidizing biocide.
