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:: Hobbs, Stephen D., Oregon State University. Forest Research Laboratory, Byars, R. H ., Henneman, D. C., and Frost, C. R.
Abstract:: The effects of artificial shading and aspect on the performance of 1-0 container-grown Douglas-fir seedlings were evaluated 1 year after outplanting on four different aspects in southwest Oregon. The test areas, all characterized by steep slopes and shallow, skeletal soils with a surface mantle of loose rock and logging slash,...

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:: Approximately 3-4 month-old containerized Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings (seed zone 262 and 271) were subjected to 6 moisture stress treatments (65, 53, 41, 29, 17 and 7% soil water content by volume of dry soil) starting July 4 to September 22, 1991 at Forest Research Laboratory's greenhouse at...

Creator:: Hobbs, Stephen D. and Oregon State University. Forest Research Laboratory
Abstract:: One-year-old container-grown Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings were outplanted on north, east, south, and west aspects on steep, skeletal Xerochrepts in southwest Oregon. After 2 years, survival rates were highest on north and south aspects, but biomass production (dry weight) was greatest on the west aspect. Shadecards, used to...

Creator:: James, Robert L., United States. Forest Service. Northern Region, and United States. Forest Pest Management
Abstract:: Investigations were conducted to understand the epidemiology of Fusarium on containerized Douglas-fir seedlings. Types and importance of Fusarium inoculum sources, relationships between seedling infection and symptom production, amounts and types of diseases that occurred throughout typical growth cycles, and the importance of secondary pathogen spread were investigated. Levels of Fusarium...
