Beech leaf disease (BLD) was first detected in 2012 in Ohio and has since spread across the eastern US and Canada. It is caused by Litylenchus crenatae mccannii (Lcm), a foliar-feeding nematode, and can result in host tree mortality within seven years. Symptoms include distinct banded leaves, premature leaf drop, and aborted bud development in Fagus spp.
