Tests to Control Fusarium Root Rot of Ponderosa Pine in the Pacific Northwest

Fusarium root rot of ponderosa and other species of pine has been a serious problem in at least two forest nurseries in the interior of Oregon and California. Most recent losses have occurred in the Forest Service Nursery near Bend, Oreg., which produces ponderosa pine. Typically, the disease kills 1- to 3-month-old seedlings by girdling the taproot at the ground line or just below the root crown. The diseased seedlings eventually turn brown and wither, as though killed by drought.
