Beech Leaf Disease (​Litylenchus crenatae mccannii)

Beech Leaf Disease (BLD) is thought to be the result of infestation by a nematode (worm) Litylenchus crenatae mccannii, but this organism has also been fund on asymptomatic trees. Signs of BLD include leaf yellowing and dark striping between leaf veins. 

Management strategies for beech leaf disease have not yet been developed. Research is still ongoing, and reports of BLD observations should be reported on the free iMapInvasives app. Location information can also be reported to NYS DEC at [email protected] or 1-800-640-0652
