Treating ash trees for this destructive non-native insect increases the chance of preserving genetic material of ash trees throughout the state. The Emerald Ash Borer Treatment Cost-Share Program can help landowners and organizations offset up to 70% of costs for treatment of ash trees through stem injections with emamectin benzoate insecticide. Payment may not exceed $10.50 per inch diameter at breast height or $2,000 in cost-share payments to landowners or $10,000 in cost-share payments per organization.
Who is Eligible
Eligible applicants include Virginia landowners and organizations (e.g., municipalities, nonprofits, educational institutions and homeowner associations).
Eligible trees must be green, white, black, blue, pumpkin or Carolina ash that are 12 inches diameter at breast height (DBH) or greater. There cannot be more than 30% crown loss on eligible trees (at least 70% live crown) and all trees must be assessed by a DOF forester prior to enrollment.
