Control and study of Hemlock Woolly Adelgid: protecting hemlocks using biological & chemical controls
Do these controls work? According to vegetation reports based on monitoring of treated sites, “results of biocontrol treatments are still in their infancy and have been mixed. Some locations show hemlocks are holding on while trees in other locations have declined severely or died. Survival may be the result of site, microclimate or other factors. Long term monitoring will reveal a clearer trend.” Look for more information in an upcoming “Dispatches.”
