Effects of Preplant Soil Treatments on Fusarium an dTrichoderma Populations and Fungal Root Colonization of 1-0 Nondiseased Ponderosa Pine Seedlings-USDA Forest Service Lucky Peak Nursery-Boise, Idaho

Preplant soil treatments were implemented to determine effects on populations of potentially pathogenic Fusarium and potentially disease-suppressive Trichoderma spp. as well as root colonization by these and other selected fungi on healthy-appearing, bare root 1-0 ponderosa pine seedlings at the USDA Forest Service Lucky Peak Nursery near Boise, Idaho. Soil treatments included fumigation with methyl bromide/chloropicrin (MBC), bare fallowing with periodic cultivation, and incorporation of two cultivars of winter Brassica cover crops.
