    Description

    Two materials, monolaurin (at two concentrations) and an unidentified species of the genus Streptomyces, were tested along with borax for ability to protect freshly cut stump surfaces of western hemlock (Tsuga heterophylla (Raf.) Sarg.) from colonization by Fomes annosus. Protectants were significantly (P<0.01) better than no treatment. The most effective treatments were borax (no treated stumps were infected) and the higher concentration of monolaurin (only 5.9 percent of treated stumps were infected).
