The potassium salt of linoleic acid, a long-chain fatty acid, inhibited growth of Poria weirii and Fomes annosus in vitro when incorporated into synthetic liquid media at concentrations of 0 1 mg/ml or higher. Increasing concentrations (up to 4.0 g/ml) resulted in significantly increasing inhibition in both fungi. Inhibitory effects were particularly striking for Poria weirii: growth was negligible at concentrations of 1.0 mg/ml or higher. Resistance of Alnus rubra to infection by P. weirii is likely due in part to alder's ability to produce linoleic acid. Forest Sci. 16:329-330.
