Scleroderris canker (American name), or Brunchorstia disease (European name), Gremmeniella abietina, is a species of fungal diseases infecting coniferous forests. The main symptom is the death of the needles, leading to the death of the tree. In the forest industry, fighting off an infection of Scleroderris canker is usually not cost-effective. Clearing is often preferred over fungicidal methods, as the latter is harmful to other living organisms.
