Impact of Annosus Root Rot Minimal 22 Years After Planting Pines on Root Rot Infested Sites
Mortality due to annosus root rot among trees of seven species on two sites was 6% or less by age ten. Previous stands on these sites had been clearcut because the disease was widespread. After 22 years neither basidiocarps of Heterobasidion annosum nor trees with symptoms of annosus root rot were present in the plantations. Planted seedlings of loblolly (Pinus taeda L.), longleaf (P. palustris Mill.), slash (P. elliottii Engelm. var. elliottii), and eastern white (P. strobus L.) pines survived well and at age 22 provided fully stocked to overstocked stands with good basal area and average dbh. Plots direct seeded with loblolly were fully stocked, whereas seeded slash and longleaf plots have always been poorly stocked. Annosus root rot is not a serious threat to regeneration on annosus infested sites. South J. Appl. For. 10:96-98, May 1986.
