  • Anthracnose (Aureobasidium apocryptum) Leaves turn brown and branches become bent and twisted, caused by a fungal foliar illness that affects plants. During damp, cool weather, this maple leaf disease is more common. removal and destroying infected leaves and limbs is the best way to prevent anthracnose on maples without chemicals.
  • Leaf spot Several fungal and bacterial illnesses may also produce this symptom. Raking up fallen leaves in the fall and removing diseased foliage and branches from the tree is the best way to prevent these illnesses from spreading.
