In the coming months, a member of the team will return to apply a fungicide known as Broadform, plus one other experimental treatment. The site will be monitored to gauge the chemicals’ effectiveness at killing the nematodes before they move into the developing buds.

“We’ve had excellent results in lab assays and toxicology work, but field testing is tricky and we continue to learn,” Borden said. “Some sites showed a dramatic reduction in nematode numbers and improvement in beech health, while at other sites, BLD progressed seemingly unabated.”

We are dealing with the Emerald ash borer that arrived via courtesy of our Chinese buddies wooden crates used for importing. really wreaking havoc and has killed an insurmountable number of trees and is headed to Canada.
myself I think the Chinese government, importers, and retail companies that used those crates/products should be held responsible but that's not going to happen. Wondering if they may find the source of the above to be similar ?
