Abstract:: Potential problem pests found were Armillaria root disease, pocket gopher, western pine shoot borer, and white pine blister rust. Early detection of problem pests allows management actions to be taken if needed to prevent serious impacts. Unit managers should check the areas periodically and call on pest management specialists to...

Abstract:: Isolates of Fusarium oxysporum, F. acuminatum, and F. sambucinum obtained from peat-vermiculite soil mixes were tested for pathogenicity on ponderosa pine, lodgepole pine, western larch, and blue spruce containerized seedlings and on germination of Scots pine and blue spruce seed. Ponderosa pine seedling were the least susceptible to killing by...

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...

Abstract:: Dwarf mistletoes still pose management problems on the Flathead Reservation. We describe a management program, to be conducted in conjunction with the silvicultural program, which will help reduce the impact of dwarf mistletoe on Douglas-fir, western larch, and lodgepole pine. This program covers fiscal years 1986 through 1990.

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...
