Saplings and small poles are usually killed quickly, while older trees may confine the fungus to a small number of roots or to the butt log and survive for many years. Trees of intermediate susceptibility are often infected but rarely killed, while tolerant species are seldom infected and almost never killed. Old infected stumps from previously infected stands are a serious problem for regeneration of highly susceptible species. Certain silvicultural procedures such as commercial thinning or uneven-aged management may make infestations worse. The disease often occurs with other root diseases such as Armillaria root rot or Annosus root and butt rot.
Laminated root rot is itself a predisposing agent for bark beetle attack.
Laminated root rot often occurs with other root diseases and predisposes trees to bark beetle attack. Always check apparent bark beetle kills for root disease signs as their presence may influence species regeneration and silvicultural methods. Control of laminated root rot is best attempted at the time of final harvest. Infected trees should be marked low on the bole so the mark remains after harvest. It is suggested that disease centers should be mapped as well as marked to enable them to be tracked over time.
