Armillaria Root Rot in Pin Oak

I recently examined a Pin Oak 45 feet high and 13 inches DBH. This tree had wilted misshapen leaves with some leaves on the ends of the branches that were over sized and misshapen.

The bark had small off white mushrooms (2mm)  in patches coming from cracks in the bark.

The soil was very moist with moss covering it. There were small yellow/ gold mushrooms growing from the soil at the base of the tree.

Diagnosis- Early stages of  Armillaria Root Rot

Treatment - Aeration and Canopy thinning

Pesticides - No known effective fungicides. Relaint systemic fungicide can be used to prevent any further fungi.

Call me the Tree Doctor

Recently I became a licensed pesticide applicator for North Carolina turf and trees. I like to think of my self as a tree doctor. I am sent to trees that are sick and diagnose them, whether it be from insects or fungus. This time of year Leyland Cypress (Cupressocyparis leylandii) can become infested with Bagworms. The proper treatment for this is to spray the infected trees with Basilis thuringiensis. This is also a treatment for spring Eastern Tent Caterpillars and Fall Webworms.

                                      
For the treatment of trees that are out of reach, such as a Pignut Hickory (Carya glabra) that I recently diagnosed with fungal Root Rot and Brown Leaf Spot fungus. Where in this case I needed to treat the foliage which was 70 to 100 feet up I used an basal injection systemic fungicide.
