Fusarium Root Disease of Western White Pine Seedlings at the Coeur D'Alene Nursery, Idaho

Root disease of 2-0 western white pine seedlings occurred at the Coeur d'Alene Nursery in 1982 within seedbeds fumigated with methyl bromide and chloropicrin. Although losses were not substantial, there were several groups of dead seedlings within affected seedbeds. Fusarium oxysporum was most often isolated from diseased roots. Other Fusarium species, including F. solani and F. roseum were isolated less frequently. Characteristics of Fusarium root disease in bareroot nursery stock are discussed.
