The spotted lantern fly has dominated public attention in the U.S., with government agencies mobilizing campaigns to stamp out the bugs. But a different pest is killing trees and confounding scientists, and it’s received little attention: nematodes.
A newly discovered nematode, or microscopic worm, has been found to be attacking beech trees across the Northeast.WILDWOOD STATE PARK, N.Y. — Matt Borden, a plant pathologist, had walked less than 50 yards into the forest when he froze in place and looked skyward.
First discovered in Ohio in 2012, beech leaf disease has now been identified in 12 states, where it’s ravaging trees in forests and back yards and costing nursery owners millions. But much remains unknown about the disease, namely, how are the nematodes spreading so rapidly and what, if anything, can be done to stop their march and save the infected trees.
“One of the main things we say on the calls is, ‘Oh, gee! You can’t find any funding,’” said Margery Daughtrey, a plant pathologist and senior extension associate at Cornell University’s School of Integrative Plant Science. “It’s a real problem.”research money“Nothing against the spotted lantern fly,” Daughtrey said, “but it doesn’t actually bother people, and it doesn't bother many plants.
But in late 2017, a plant pathologist in Ohio, David McCann, was studying infected beech leaves under a microscope when he saw what he first thought were tiny leaf hairs. Then he noticed that they were moving — a eureka moment.Litylenchus crenatae mccannii The nematodes feast on the buds and leaves of beech trees. As the parasites multiply, the leaves develop dark bands, crinkle and thicken. In time, the buds die and the crown of the beeches thin out, hampering photosynthesis and hastening the trees’ death.No other leaf-eating nematode is known to infect a large forest tree in North America. The vast majority of nematodes dwell in the soil and attack roots or underground crops such as potatoes and carrots.
The USDA’s Animal and Plant Health Inspection Service, or APHIS, has allocated more than $108,000 for a research project studying the risks of beech leaf disease in several states. Beth Brantley, a research scientist with Bartlett Tree Experts, walks near beech trees in Wildwood State Park, N.Y., on July 13. The trees are missing their leaves because of beech leaf disease.Most of the researchers worked for Bartlett Tree Experts, a private company with a research arm and laboratory based in Charlotte, North Carolina. The group included Borden and his colleagues, Andrew Loyd and Beth Brantley.
