Creator:: James, Robert L. and Gilligan, Carma J.
Abstract:: An evaluation of the efficacy of steam treatment on reducing levels of Fusarium, Cylindrocarpon, and Trichoderma within styroblock containers was conducted at the Plum Creek Nursery in Pablo, Montana. Although levels, of both Fusarium and Cylindrocarpon were significantly reduced by cleaning, relatively high populations of both these fungi persisted after...

Abstract:: Two methods attempting to stop marginal spread of a root disease center in Douglas-fir were evaluated within the Flathead Indian Reservation, Montana. The first method was to cut all living trees within a 1-chain strip outside the edge of the infestation. The second method was to uproot all trees for...

Abstract:: A root disease evaluation was completed for the Ducharme logging unit near the southeast corner of Flathead Lake. Extensive root disease was found on Douglas-fir throughout the unit. The major pathogen on the site was Armillaria meilea. Black stain (Verticicladiella sp.) was isolated from one tree which was also infected...

Abstract:: Tests were conducted to evaluate efficacy of dry heat (82.2°C for 10, 20, and 60 minutes) to reduce colonization by selected fungi within styroblock containers and residual seedling roots left in containers after seedling extraction. Dry heat alone was generally ineffective in significantly reducing fungal colonization. However, simply wetting container...

Creator:: James, Robert L. and United States. Forest Service. Northern Region
Abstract:: Cones of Douglas-fir and ponderosa pine with extensive mold on external portions of scales were sampled for presence of fungi potentially pathogenic to conifer seedlings in nurseries. The major colonizers of cone scales and external seedcoats for both conifer species were Trichoderma spp. Penicillium spp. were also very common. The...

Creator:: James, Robert L. and United States. Forest Service. Northern Region
Abstract:: Investigations were conducted to determine importance of Fusarium as a pathogen on Douglas-fir seed and containerized seedlings at the Plum Creek Nursery during 1985. Fusarium oxvsnorum was occasionally isolated from necrotic lesions on young germinants that lacked foliar symptoms. Low levels of F. oxvsnorum were detected on three of four...

Creator:: James, Robert L. and United States. Forest Service. Northern Region
Abstract:: Causes of mortality of containerized western larch seedlings at the Champion Timberlands Nursery, Plains, Montana, were investigated. Seedlings were rated for disease severity based on extent of foliar decline symptoms and fungal isolations made from their roots. Isolations were also made from selected larch seed. Consistent associations between root colonization...
