Title: Observations on root disease of container whitebark pine seedlings treated with biological controls
Author: Dumroese, R. Kasten

Description: I observed that whitebark pine (Pinus albicaulis Engelm. [Pinaceae]) germinants treated with biological controls, one commercially available (Trichoderma harzianum strain T-22), and the other being studied for potential efficacy (Fusarium oxysporum isolate Q12), experienced less seedling mortality caused by root disease than did a non-treated control. Seedlings treated with the biological controls and nonsymptomatic seedlings in the control treatment had similar morphology. The simple use of biological controls may be useful to nursery managers looking to reduce incidence of root disease in their container crops.
Keywords: Pinus albicaulis, whitebark pine, Fusarium oxysporum, Trichoderma harzianum, Cylindrocarpon
