Ash Tree Diseases
The most common diseases that affect Ash trees are Ash yellows, Verticillium Wilt, ash rust, and Ash Anthracnose. Ash yellows is a slow-killing tree disease caused by a microorganism called Candidatus fraxinii that harms a tree’s vascular system. This disease tends to mostly affect white ash and green ash species. Although there is no cure for Ash yellows, pruning and fungicide treatments in its early stages is an effective way to manage Ash yellows. Verticillium Wilt, ash rust, and Ash Anthracnose are fungal diseases that result in leaf wilting, canopy dieback, and more. These diseases are generally treated with pruning and fertilizing.
Ash Tree Pests
By far the most common pest problem for Ash trees are Emerald Ash Borers (EAB). Emerald Ash Borers are small metallic green beetles that target Ash trees exclusively. Larvae look like small maggots or white worms, while adult beetles are about the size of a raisin, and have metallic green backs. Adults lay eggs inside the bark, and when their larvae is born, they eat their way to the surface until full-grown. Once adults, they emerge from the bark, leaving behind D-shaped exit holes in the wood. Additional pests that attack and infest Ash trees include oystershell scales, ash plant bugs, and aphids.
In order to prevent pest infestations, arborists commonly apply systematic insecticides for optimal tree protection. Systematic insecticides contain the active ingredients dinotefuran, emamectin benzoate, or imidacloprid. These chemicals have all been registered with the Environmental Protection Agency and deemed appropriate for agricultural applications.
