TREE DISEASE – IDENTIFICATION AND SYMPTOMS
The bulk of tree diseases are caused by forms of fungi or bacteria. There are a plethora of fungi and bacteria, and tree diseases are spread via causal agents Arborists can diagnose tree diseases and provide treatment options.
Common Tree Diseases
Tree Blight - is caused by fungus or bacteria. Tree with blight will show browning of the leaves, wilting, and dying of twigs and leaves in the majority of its canopy.
Dutch Elm Disease - is a fungal illness affecting the vascular system of American Elm trees. The fungus blocks the vascular system preventing the movement of water throughout the tree. This will cause wilting and eventually death. The primary symptom of DED is dying branches. The best way to diagnose DED is the cut a living limb and ascertain if there is brown streaking in the wood. Beetles are the primary causal agent that spreads DED.
Scab - is a kind of fungus that usually is displayed on the fruit of apple trees. They are first displayed as lesions on leaves, and then they crack or harden to scabs on the apples.
Fire Blight - is caused by bacteria, it generally infects pear and apple trees.
Blotch - is a kind of fungus that produces brown or black blotches on leaves that are generally larger than leaf spots.
Leaf Spot - are small spots of dead tissue found on leaves.
Oak Wilt - is a fungus that impacts red oaks and is spread by bug vectors via the root graft. The results of oak wilt are leaf discoloration, defoliation, dropping or wilting of leaves because of lack of water, and death.
Leaf Scorch - impacts a variety of species generally caused by extremes in climate. Scorch causes dead areas on leaves or browning near the ends of the leaf near the circumference.
Pine Wilt - is caused by Pinewood Nematode as a beetle eats on phloem or if a female beetle produces effs on the wood. The results of pine wilt are the browning or dying of the needles in major portions in many varieties of pine trees.
Verticillium Wilt - is a soil-based fungus that causes the leaves to quickly wilt, turn yellow, and eventually die. The vascular system and wood under that bark of the tree will show streaks of discoloration.
Anthracnose - is a fungal disease that creates leaf blight. It generally impacts ash, oak, dogwood, and sycamore trees. The disease caused discoloration within the leaf veins and brownish blotches.
Armilarria Root Rot -is another soil-based fungus and is often times called "shoestring root rot". The rot results in mushrooms growing out of the decaying wood. The root rob is spread and created by root-like formations called rhizomorphs.
Hypoxylon Canker - is a fungus the generally impacts oak trees. It is caused by drought and creates necrosis in the tree bark. It is very simple to diagnose as the tree bark changes to a light gray while color.
Canker - is a fungus that creates a local necrosis in the tree's cambium and bark. Canker causes dead areas in the tree bark.
Leaf Blister is known as a fungus leaf spot illness that looks like a blister on humans. It is generally light green and welted spots on the leaf. It most commonly impacts oak trees.
