Abstract
A report of bud necrosis of white spruce, Picea glauca (Moench) Voss, within spruce budworm, Choristoneura fumiferana (Clem.), infested stands was investigated. No significant differences in bud mortality could be determined between infested and non-infested stands, but a nine-fold higher incidence of Pullularia pullulans (deBary) Berkhout was measured in infested stands. This later finding suggested a marked build-up of the fungus as a result of conditions created by the budworm infestation.
