Over the last few years, Beech trees have been under attack in our region. However, Bartlett has been successfully battling this disease and is here to help you save your Beech trees in Lebanon and Lancaster counties.
What is Beech Leaf Disease?
Beech Leaf Disease (BLD) is a serious condition affecting beech trees, caused by the microscopic nematode Litylenchus crenatae mccannii. First discovered in Ohio in 2012, the disease has spread rapidly across North America, leading to severe canopy dieback and, eventually, tree mortality. Symptoms include dark green striping between leaf veins, thickened leaf tissue, and eventual curling and shriveling of leaves. Trees that have little to no symptoms; will get this disease, so preventative treatment is highly recommended.
How do I save my tree?
Bartlett’s research staff have been investigating potential treatment options for several years. Based on two major discoveries, followed by numerous field trials and lab studies, Bartlett scientists have developed two separate and distinct management programs shown to effectively suppress BLD symptoms.
First is a program that involves foliar applications to small beech trees, including hedges. This program begins in mid-summer and continues through the peak nematode activity season, mid-to-late summer through early fall.
The second program, intended for medium to large beech (including those near water), is a root flare injection implemented by mid-summer. Research indicates a single injection treatment can provide significant BLD suppression for a minimum of two seasons.
Both programs reduce nematode populations at a critical stage of their life cycle and minimize migration into developing vegetative buds. Cultural treatments and soil care remain important aspects of beech health management, as BLD can negatively impact mycorrhizal root associations.
Beech trees are vital to our ecosystem. Their dense canopy provides a habitat for numerous plant species, creating a rich and diverse ecosystem. Their Beech nuts also provide food for many animals and their thick dense canopy is crucial for bird habitat and the forest floor.
It’s important that we save this native tree so our children can experience their beauty.
