Effects of Preplant Soil Treatments on Fusarium an dTrichoderma Populations and Fungal Root Colonization of 2-0 nondiseased Western White Pine Seedlings-USDA Forest Service Nursery Coeur D'Alene, Idaho

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 fumigation with dazomet, bare fallowing with periodic cultivation, steam treatment, fallowing with amendments of Trichoderma harzianum biocontrol agents (SioTrek® and University of Idaho isolates [UI]), and incorporation of two cultivars of winter Brassica cover crops followed by biocontrol amendments (UI).
