Understanding Tree Cankers: Causes, Effects, and Treatment Options
Tree cankers are localized dead areas on trees caused by fungi and bacteria, often resulting from mechanical and environmental damage. These infections can begin in trees as young as two years and symptoms may appear within 14 to 60 days. Treatment typically involves cutting off infected limbs. Cankers primarily affect deciduous trees, particularly weak, young, and vulnerable fruit trees. Signs include rough bark, splitting wounds, and dead foliage. Understanding these factors helps in maintaining tree health and preventing the spread of cankers.

Organisms it effects: • Deciduous Trees • Weak, young and vulnerable • Fruit trees
Key Features: • Rough or cracked Bark • “Wounds” splitting crevices in bark • Dead leaves or needles • Small fungal spore forming structures either in the centers or around the edges of tree
