Emerald Ash Borer a huge concern in Bruce and Grey counties
By Liz Dadson
Concern is rising about the survival rate of ash trees in Bruce and Grey counties, now that the presence of the Emerald Ash Borer has been confirmed in a number of locations throughout both counties.
Jim Penner, manager of forestry with Saugeen Conservation, says the agency has been receiving a lot of calls from landowners, churches, municipalities, etc., worried about what will happen to their trees and woodland lots.
"We've treated a number of ash trees already," says Penner, "but the hot humid weather experienced recently did not help things. When it gets really hot, the trees shut down and the uptake of the treatment can literally take hours.
"The treatment for the Emerald Ash Borer can only take place in the months of July and August which is timed to adult emergence and the start of egg laying."
The Emerald Ash Borer first made its appearance in the United States and Canada in 2002 and, to date, has killed between 50-million to 100-million ash trees. The Emerald Ash Borer targets all species of ash trees.
"The problem is that the larvae (left) bore into the trunks of ash trees and feed their way around the trunk eventually girdling and killing the tree (below)," says Penner.
"They are very destructive, resulting in the death of even large trees within a few years."
The inoculation treatment provides protection for highly- valued ash trees for up to two years, upon which time application may have to be repeated. The process can take a few minutes or a few hours. Costs per tree can vary between $100 and $500, depending on size.
The process must be done during the summer months to ensure that eggs and/or larvae have been destroyed.
The product used to treat the Emerald Ash Borer is call TreeAzin. It is derived from the Neem tree, an evergreen native to India. TreeAzin is applied by trained, licensed staff and degrades naturally within the tree tissues.If you have ash trees you want to protect, contact Penner at Saugeen Conservation, 519-367-3040, Ext. 233 or firstname.lastname@example.org.
