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...

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...

Creator:: Merrill, L. M. and United States. Forest Service. Northern Region
Abstract:: Dwarf mistletoe is a serious problem on the Flathead Indian Reservation. Since the early 197o's, a procedure called thinning-sanitation has been applied to lightly infested stands. Evaluation of this procedure indicated that average dwarf mistletoe infection levels now range from 7 to 50 percent in larch and Douglas-fir treated 10...

Creator:: Stipe, Lawrence E., Dewey, Jerald E., and United States. Forest Service. Northern Region
Abstract:: Trees in a Douglas-fir stand infested with western spruce budworm were treated with a systemic insecticide to protect cone and seed production at three locations in Montana during 1983. Treatments applied were (1) acephate as an Acecap implant, (2) acephate as an Inject-A-Cide injection, and (3) control. Potential cone-bearing trees...

Creator:: Tunnock, Scott, Bousfield, Wayne E., and United States. Forest Service. Northern Region
Abstract:: An evaluation during the summer of 1985 showed that parasites were still exerting control on the larch casebearer on the Flathead NF. Parasitism ranged from 4 to 60 percent and averaged 25.2 percent in the 12 areas surveyed. Four species of parasites were involved. The most abundant was Agathis pumila...
