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 bare root (2+1)
Douglas-fir transplants were very low, regardless of soil fumigation. Fumigation reduced disease on
bare root (2+1) white pine transplants, but did not improve survival of container (plug+1) white pine
transplants. Seedling height growth during the first year after transplanting was significantly
improved by soil fumigation. Fusarium oxysporum was commonly isolated from soil and roots of
diseased bare root transplants. Fusarium proliferatum was commonly isolated from the roots of
container transplants. Soil fumigation may not necessarily improve survival and performance of all
types of conifer transplants in nurseries. |
