Fungal canker disease

Fungal cankers can cause injury to individual limbs or the trunk of a spruce tree. The fungal infection acts link a tourniquet, cutting off the flow of water and nutrients to the infected limb or trunk above the infection. This causes either spotty limbs to die in the trees canopy or for the entire top of the tree to die above the infection. For the most part fungal cankers can be diagnosed visually, based on the syptoms the tree is showing and the presence of white sap dripping from a visible wound. For more information on a common fungal canker, cytosproa canker, please use the following link:
