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...

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...

Mountain pine beetle infestation in ponderosa pine on Crow/Northern Cheyenne Indian Reservations, Montana, 1984

Creator:: Gibson, Kenneth E., McGregor, Mark D., Oakes, Robert D., and United States. Forest Service. Northern Region
Abstract:: The mountain pine beetle infestation existing on the Crow Indian Reservation (IR) since the early 1970's, and later developing principally in the western portion of the Northern Cheyenne IR, continued into 1984. Survey results indicate the infestation is still building on both Reservations. To help develop beetle management strategies appropriate...

An evaluation of fungicides to control Diplodia tip blight at the Fantasy Farms Nursery, Peck, Idaho

Creator:: James, Robert L., Schwandt, John W., Woo, John You, and United States. Forest Service. Northern Region
Abstract:: Benomyl and chlorothalonil were tested on 2-0 bareroot ponderosa pine seedlings as a means to reduce impact of Diplodia tip blight at the Fantasy Farms Nursery, Peck, Idaho. Infection levels were not adequate to assess effectiveness of the fungicides. However, techniques were developed which can be used to assess efficacy...

Pathogenicity of Fusarium from forest seedling nurseries on Douglas-fir and ponderosa pine seedlings

Creator:: James, Robert L. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Eighteen isolates of Fusarium comprising four species (F. oxysporum, E. avenaceum, E. acuminatum, and F. sambucinum) isolated from diseased conifer seedlings from nurseries were tested for pathogenicity on Douglas-fir germlings. Three of the most pathogenic F. oxysporum isolates on Douglas-fir germlings were also tested on ponderosa pine germlings and older...

Control of the western pine shoot borer Eucosma sonomana kearfott in selected ponderosa pine plantations in northern Idaho and western Montana : progress report no. 2

Creator:: Dewey, Jerald E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Two blends (Natural and Phillips) of the western pine shoot borer pheromone, formulated as Hercon Luretape, were applied to six ponderosa pine plantations in northern Idaho and western Montana in 1984. The treatment was approximately 21.6 grams of pheromone per hectare. Significant reductions in damage have occurred in all treated...

Evaluation of a mountain pine beetle infestation in second-growth ponderosa pine on the Crow Indian Reservation, Montana, 1979

Creator:: Gibson, Kenneth E., McGregor, Mark D., Dewey, Jerald E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The mountain pine beetle infestation in Corral, Little Corral, and Cache Creeks on the Crow Indian Reservation, Montana has been increasing for the past several years. Trees killed per acre averaged 38.8 in 1979. Our predictions for the future trend of the infestation, plus management alternatives to lessen its severity,...
