Outplanting survival of cylindrocladium root rot affected black spruce seedlings

Picea mariana seedlings lifted from nursery fields known to have cylindrocladium root were field planted and monitored for survival and growth. By the end of the second season >39% of seedlings had died; >77% of this mortality occurred within six months of planting. Significantly higher levels of mortality caused by Cylindrocladium floridanum and total mortality occurred in seedlings with symptomatic shoots or within root lesions and nonsymptomatic shoots. -from Authors
