Garden Pest and Plant Disease Listing - AR
ARMILLARIA ROOT ROT: This is a soil borne disease common in parts of the dry-summer western U.S. It infects the roots of many plants, yellowing the leaves, causing wilting and dieback. Signs of infection include pale brown mushrooms growing around the base of the plant and fan-shaped, whitish mold under the bark. Infected plants are hard to save. An arborist may be able to help save large trees. A method of control is to plant resistant species. Also called Oak Root Fungus.
