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...

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...

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....

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...

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...

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...

Chemical applications for control of armillaria root rot of Ponderosa pine

Creator:: Filip, Gregory M.
Abstract:: Root rot caused by Armillariella mellea creates roughly circular disease centers of infected dead and dying trees in the younggrowth ponderosa pine forest under study. Research objectives concerning chemical control of the disease were: 1) to test the effectiveness of certain chemicals in protecting living pines adjacent to disease centers...

Infection of stressed ponderosa pines by Armillariella mellea from indigenous and artificial inoculum sources

Creator:: Fuller, Lloyd Randolph
Abstract:: Armillariella mellea (Vahl. ex Fr. ) Karst. was grown aseptically in hazel stems (Corylus cornuta var. californica) which were used in the forest to infect 290 ponderosa pines (Pinus ponderosa Laws.) which had been "stressed" in five different manners plus two control groups. All trees were inoculated twice giving a...
