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...

Resistance of Botrytis cinerea to vinclozolin, iprodione and dicloran

Creator:: James, Robert L., Gilligan, Carma J., and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Isolates of Botrytis cinerea from containerized conifer seedlings from two nurseries in the Northern Rocky Mountains were exposed to the dicarboximide fungicides vinclozolin and iprodione and the chlorinated nitroaniline fungicide dicloran to evaluate occurrence and characteristics of resistant strains. The isolates were grown on test media prepared by incorporating the...

Evaluation of proposed dwarf mistletoe projects on the Lolo National Forest, Montana

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Residual Douglas-fir, western larch, and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning, will reduce mistletoe intensity and increase future volume yields. Present net worth of the project is $48.05/acre. Benefit cost ratio is 1.97/1. Use of pest...

Dwarf mistletoe management in the Northern Region : is it cost-effective?

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: An investment is an expenditure made with expectation of future gains, financial or otherwise. Dwarf mistletoe management, and even forest management itself, often involves investment for social and community benefits without expectations of direct financial gain. The USDA Forest Service Northern Region's dwarf mistletoe program, 1966 to 1981, is used...

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...

Conifer root diseases on the Kootenai National Forest, Montana

Creator:: James, Robert L., Stewart, C. A., and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: A survey for incidence and distribution of root diseases was conducted on the Kootenai National Forest using timber inventory subcompartments as primary sample units. Root diseases were located within 23 of 75 sampled subcompartments. At least 1.1 percent of the commercial forest lands within the Forest are infested with root...

Douglas-fir tussock moth adult male survey north Idaho and western Montana, 1982

Creator:: Dewey, Jerald E., Livingston, R. Ladd, Kohler, Steve, and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Douglas-fir tussock moth populations are monitored annually in northern Idaho and western Montana to insure early detection of changes from endemic to outbreak population levels. Adult moth trapping in 1982 was intensified and expanded into additional areas from 1981 because of concern that with each passing year the probability of...

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...

Fungicide tests to control Botrytis blight of containerized western larch at the Champion Timberlands Nursery, Plains, Montana

Creator:: James, Robert L., Genz, Daryl, and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Five fungicides were evaluated to control Botrytis blight of containerized western larch seedlings at the Champion Timberlands Nursery, Plains, MT. Fungicides were applied at biweekly intervals before and after seedling inoculation with Botrytis. Vinclozolin (Ornalin®) caused severe phytotoxicity to seedlings, resulting in enhanced mortality and premature needle loss. Captan and...

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...

Abstract:: Residual Douglas-fir and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning of dense patches of regeneration, will reduce dwarf mistletoe intensity and increase future volume yields.

Abstract:: Tests were conducted to determine levels of tolerance of 10 Botrytis cinerea isolates from the Flathead Indian Reservation greenhouse (Ronan, MT) to six fungicides. In vitro growth and conidial germination on fungicide-amended potato dextrose agar were used as criteria for assessing tolerance. All tested isolates were tolerant to benomyl and...
