In situ wood preservative treatment of a wooden railroad tie. The method includes the steps of injecting a paste-like preparation having a water soluble fungicide into one or more unoccupied spike holes in the rail supporting tie plate. The preparation lodges in crevices and recesses in communication with the spike hole, killing existing decay fungi. Over a period of time the fungicide follows existing or subsequently developed paths of moisture to more remote decay sites.
