Monitoring root disease mortality : establishment report

Creator:: Hagle, Susan K. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Two thousand and thirty-nine trees on 213 plots are being monitored yearly for root disease infection and mortality. Three compartments on the Fernan Ranger District of the Idaho Panhandle National Forests are the site of the project. Relationships between factors such as species, aspect, slope, elevation, habitat type, stand appearance...

Root disease survey on the Nezperce National Forest, Idaho

Creator:: James, Robert L., Stewart, C. A., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An impact survey to determine extent and distribution of root disease centers was completed for the Nezperce National Forest, Idaho, in 1980. Lowlevel color infrared photography was used to delineate root disease centers within National Forest inventory subcompartments. Suspected root disease centers were ground checked to determine associated fungi and...

Color infrared aerial photography for root disease detection in the Northern Region

Creator:: Williams, R. E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: "Holes" with dead, dying, and downed trees in the forest canopy could be reliably identified on 9- by 9-inch Kodak Ektachrome Infrared Aero film 2443 as root disease centers. Film scales larger than 1:4000 were best for detection of these "holes." Most commonly occurring causal organisms in root diseased trees...

Root disease of containerized conifer seedlings, Western Forest Systems Nursery, Lewiston, Idaho

Creator:: James, Robert L., United States. Forest Service. Northern Region, and United States. Forest Pest Management
Abstract:: Investigations of containerized western white pine, western larch, and Douglas-fir seedlings at the Western Forest Systems Nursery in Lewiston, Idaho, revealed that many seedlings were colonized with Fusarium oxysporum although they lacked severe disease symptoms. White pine seedlings were also infected with Pythium spp., probably as a result of sowing...

Root diseases of western white pine transplants at the USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., Gilligan, Carma J., and United States. Forest Service. Northern Region
Abstract:: Mortality of western white pine transplants used to assess resistance to blister rust at the USDA Forest Service Nursery in Coeur d'Alene, Idaho was likely due to extensive root infection by Pythiva app. Severity of foliar symptom production was significantly correlated with extent of root system colonization by these fungi....

Incidence of root pathogens on Douglas-fir within the Reuben's Reserve, Nez Perce Indian Reservation, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Root diseases were evaluated on the Reuben's Reserve, Nez Perce Indian Reservation, Idaho. Nineteen trees adjacent to two suspected root disease centers were pushed with a D-6 tractor to expose their root systems. Extent of root necrosis and decay was determined and related to level of crown thinning, chlorosis, and...

Comparison of Phellinus weirdi root rot damage in a 60-year-old Douglas-fir (Pseudotsuga menziesii) stand with the damage in the preceding old-growth stand

Creator:: Tkacz, Borys M.
Abstract:: Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was studied in two successive stands in the Oregon Coast Range. Damage due to the disease in a 60-year-old second-growth stand was compared with incidence in the preceding 300-year-old stand on the same site....

Establishment report : permanent plots to evaluate the effects of Armillaria root disease in precommercially thinned stands

Creator:: Byler, James W., Stewart, C. A., Hall, L. D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Methods used to establish permanent plots in precommercially thinned and unthinned stands to monitor root disease development are described. Plots were established in 22 Armillaria-infested stands in northern Idaho and western Montana. The proportion of trees dead and infected was significantly higher for planted than for natural regeneration at the...

Nursery conifer diseases : evaluation of Benomyl to control root disease of Engelmann spruce seedlings

Creator:: Williams, Ralph E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The benomyl fungicide, rersan, applied at 7 and 14 pounds active ingredient per acre, on April 26 and July 25, 1973, was ineffective in reducing mortality in 2-0 Engelmann spruce seedlings derived from two different seed sources growing in three different nursery sections at the USFS Coeur d'Alene Nursery.
