Investigations of Fusarium Diseases within Inland Pacific Northwest Forest Nurseries

James, R. L. and Dumroese, R. K. IN: Proceedings of the 53rd Western International Forest Disease Work Conference, 2005, p. 3-11. USDA Forest Service, Intermountain Region. 2006.

Diseases caused by Fusarium spp. within forest nurseries have been investigated in North America for nearly a century. However, they still severely impact production of high-quality seedlings at many nurseries. Most previous investigations focused on diseases in bareroot nurseries and very little was known about disease epidemiology or procedures to reduce disease impacts in container nurseries. Therefore, we began investigating diseases associated with Fusarium spp. more than 20 years ago. Our goal was to understand disease etiology, sources of pathogen inoculum, and various aspects of disease epidemiology specific to greenhouse environments. This information would lead to developing improved disease control.
