Reduction in growth of pole-sized Ponderosa pine related to a Pandora moth outbreak in central Oregon

Creator:: Cochran, P. H.
Abstract:: A pandora moth (Coloradia pandora Blake) outbreak began in 1991 in a ponderosa pine (Pinus ponderosa Dougl. ex. Laws) spacing study area that also included scattered sugar pine (P. lambertiana Dougl). The relation of defoliation to five tree spacings (with and without understory vegetation) was examined, and stand growth reduction...

Effects of pre-sowing soil treatments on root colonization of 1-0 ponderosa and lodgepole pine seedlings by potentially-pathogenic fungi, USDA Forest Service Lucky Peak Nursery, Boise, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Healthy-appearing 1-0 ponderosa and lodgepole pine seedlings were assayed for root infection and colonization by potentially-pathogenic fungi following pre-sowing soil treatments which included methyl bromide/chloropicrin (MBC) fumigation, fallowing with or/without periodic cultivation, and amending soil with mushroom composts or undecomposed sawdust. Levels of root colonization by Fusarium spp. on both...

Control of the western pine shoot borer Eucosma sonomana Kearfott in selected ponderosa pine plantations in northern Idaho and western Montana

Creator:: Dewey, Jerald E., Livingston, R. Ladd, Kohler, Steve, and Sartwell, Charles
Abstract:: A synthetic pheromone of the western pine shoot borer, Eucosma sonomana Kearfott, has been used successfully as a 'mating disrupter in northern Idaho and western Montana since 1984. Infestation levels in treated ponderosa pine plantations declined from an average of 28 percent infested in 1983 to 5.5 percent by 1986....

Association of Fusarium with nondiseased containerized ponderosa pine seedlings at the USDA Forest Service Nursery, Coeur D'Alene, Idaho

Creator:: James, Robert L., Gilligan, Carma J., United States. Forest Pest Management, and United States. Forest Service. Northern Region
Abstract:: A total of 45 nondiseased containerized ponderosa pine seedlings from 10 seedlots were sampled at three different times during the growing season for root infection by Fusarium and Trichoderma at the USDA Forest Service Nursery in Coeur d'Alene, Idaho. More than 90 percent of the seedlings had roots infected with...

Mexacarbate and Bacillus thuringiensis for control of pine butterfly infestations : Bitterroot National Forest, Montana, 1973

Creator:: Dewey, Jerald E. and United States. Forest Service. Northern Region
Abstract:: Aerial application of mexacarbate and Bacillus thuringiensis Berliner was tested against pine butterfly, Neophasia menapia (F. and F.). These were applied to 40-acre plots on the Bitterroot National Forest and adjacent State and private lands during June 1973. Two concentrations of each material were tested; these were 0.15 and 0.30...

Fungi on Douglas-fir and ponderosa pine cones from the USDA Forest Service Nursery, Coeur d'Alene, Idaho

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...

Needle tip dieback of ponderosa pine seedlings at the Coeur d'Alene Nursery, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Needle tip dieback of 2-0 ponderosa pine seedlings at the Coeur d'Alene Nursery was investigated. Organisms associated with dieback symptoms were identified and infected trees were transplanted to determine disease effects on survival. The major fungus colonizing necrotic needles was Lophodermium nitens, a close associate of L. pinastri. The fungus...

Evaluation of mountain pine beetle infestations, Wolf Mountains, Crow Indian Reservation, Montana, 1973

Creator:: McGregor, Mark D., Kohler, Steve, Ferry, Gardner, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Mountain pine beetle reached epidemic levels in second-growth ponderosa pine stands on Bureau of Indian Affairs and private lands on the Crow Indian Reservation. Approximately 9,106 trees containing 420,266 merchantable board feet were killed from 1971 to 1973. This is about 24 percent of the merchantable ponderosa pine in stands...
