Effects of preplant soil treatments on Fusarium and Trichoderma populations and fungal root colonization of 2-0 nondiseased western white pine seedlings - USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Preplant soil treatments were implemented to determine effects on populations of potentiallypathogenic Fusarium and potentially disease-suppressive Trichoderma spp. as well as root colonization by these and other selected fungi on healthy-appearing, bare root 2-0 western white pine seedlings at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. Soil treatments included...

Fusarium root disease of western white 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:: Root disease of 2-0 western white pine seedlings occurred at the Coeur d'Alene Nursery in 1982 within seedbeds fumigated with methyl bromide and chloropicrin. Although losses were not substantial, there were several groups of dead seedlings within affected seedbeds. Fusarium oxysporum was most often isolated from diseased roots. Other Fusarium...

Effects of spring applications of dazomet on root diseases and performance of Douglas-fir and western white pine transplants, USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Tests were conducted at the USDA Forest Service Nursery, Coeur d'Alene, Idaho to evaluate effectiveness of spring fumigation with dazomet to improve survival and performance of Douglas-fir and western white pine transplants. Spring fumigation greatly reduced populations of potentially pathogenic Fusarium and Pythium spp. Disease levels of container (plug+1) and...

Effects of topical application of the biological control agent Biotrek on production of bareroot Douglas-fir and western white pine seedlings, USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: A preliminary evaluation of the biological control formulation of Trichoderma harzianum marketed as BioTrek® was conducted on bareroot Douglasfir and western white pine seedlings at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. The biocontrol material was applied topically on seed shortly after sowing and comparisons made between treated and...

Biological and economic feasibility of pruning and excising white pines for blister rust control

Creator:: Hagle, Susan K. and Grasham, John L.
Abstract:: White pine plantations which were established in 1968 on 88 acres of the Palouse Ranger District, Clearwater National Forest, were treated by pruning and canker excision to remove lethal white pine blister rust cankers. The success rate 15 months after treatment was 98 percent for pruning and 81 percent for...

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....

Noneffectiveness of Ribes eradication as a control of white pine blister rust in Yellowstone National Park

Creator:: Carlson, Clinton E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Eradication of Ribes spp. to control white pine blister rust in Yellowstone National Park was started in 1947. In 1968 this study was initiated to evaluate the previous control effort. Ribes eradication was suspended in 1968 in 18 white pine stands and Ribes and rust were allowed to increase within...
