Investigations were conducted from 1998-
2000 at the Potlatch Corporation's
Cherrylane Seed Orchard near Lewiston,
Idaho to evaluate presence and extent of
potentially pathogenic fungi on roots of
diseased stock and within the soil in current
and proposed plantation sites. The most
common group of pathogens encountered
was Fusarium spp.; F. oxysporum was by far the most common colonizer of tree roots and
soil. Phytophthora spp. (P. cacta rum and P.
pseudotsugae) and Pythium spp. (P.
irregulare and P. ultimum) were also common
root and soil colonizers. Cylindrocarpon spp.
(C. destructans and C. tenue) were isolated
at lower frequencies. Soil solarization with a
thin plastic tarp during the summer effectively
reduced populations of potential soil-borne
pathogens. Managers should continue to
monitor pathogen populations on stock and
within soil of proposed plantation sites in
order to reduce future disease impacts. |
