You are in a pine forest and you see red needles, a sign of crown mortality. At your feet, nearby, a stump lies amid dead or dying trees. You also observe fruiting bodies of fungi at the root collar of the stump or neighbouring trees. A little further on, you notice decline, and circular gaps in which all of the pines look dead. What you could have before you is a stand affected by annosus root and butt rot.
Plain Language Summary
This publication reports on a method for preventing annosus root and butt rot.
Freshly cut stumps in a pine forest are the ideal spot for a fungus colony causing annosus root and butt rot to develop. This fungus (Heterobasidion irregular) can survive for decades in the roots, which explains the difficulty in eradicating it. The Canadian Forest Service, in collaboration with a private sector partner and a university, developed a biological control product containing spores of a fungus that blocks the development of annosus root and butt rot without causing damage to pine trees.
Branching Out is a series of plain language fact sheets describing Laurentian Forestry Centre research projects.
