The monoterpenes phenylpropanoid, 4-allylanisole, was highly inhibitory to all three fungi. a-and /3-pinene significantly stimulated the linear growth of one of the Results suggest that the production of this compound may be an important mycangial fungi, a Sporothrix species. Growth of the other, a loblolly pine defense mechanism against attack by the southern pine beetle basidiomycete, was significantly inhibited by a-and/3-pinene and by most and fungi associated with it. Additional key words: resin system, tree resistance.
