IFB 012018 - Gypsy Moth Program Emerald Ash Borer Treatment

Injection of ash trees with the insecticide containing the active ingredient Emamectin Benzoate to control Emerald Ash Borer (EAB)
 
Bay County is seeking to enter into a four (4) year contract for the treatment of ash trees that are infested with the invasive beetle, (Agrilus planipennis) Emerald Ash Borer (EAB).  All trees included in this contract are located on public land in open lawn type areas. Treatment will be done using an injected systemic insecticide formulation  containing of not less than 4% Emamectin Benzoate specifically labeled for trunk injection to control EAB in ash species (Fraxinus spp.) Maps and tree inventory for the first treatment year (2018) can be found in Exhibits A1 and A2. In subsequent years, 2019, 2020 and 2021, the ash trees included in this treatment project will be divided into groups containing one third or up to 1100 of the eligible trees. It is the intention of the County to treat groups of trees on a three (3) year rotating schedule.  The total number and cumulative diameter the trees treated each year will be determined by Bay County after review of the trees for health in the fall prior to the beginning of the treatment period.
