| dc.description |
A preliminary evaluation of the biological control
formulation of Trichoderma harzianum marketed
as BioTrek® was conducted on bareroot Douglasfir
and western white pine seedlings at the USDA
Forest Service Nursery, Coeur d'Alene, Idaho.
The biocontrol material was applied topically on
seed shortly after sowing and comparisons made
between treated and untreated 1-0 and 2-0
seedlings. First-year Douglas-fir height and
second-year white pine height and diameter were
not affected by the treatment. BioTrek®
significantly reduced white pine seedling root
infection by Cylindrocarpon spp., but not by either
Fusarium or Trichoderma spp. The major
Fusarium species isolated from roots of nondiseased
seedlings was F. oxysporum. Further
tests of BioTrek® are underway at the nursery. |
