Description:
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.
