7. Annual Treatment Area Thresholds Pesticide Use Annual Threshold Mosquitoes and other flying insect pest control640 acres of treatment Aquatic Nuisance Plant and algae control In Water 20 acres of treatment At Water’s Edge 20 linear Miles of treatment Aquatic Nuisance Animal Control In Water 20 acres of treatment At Water’s Edge 20 linear Miles of treatment Forest Canopy Pest Control640 acres of canopy

8. Treatment Area Calculations Area of applications made to: 1) water’s of the state of Michigan, and 2) conveyances with a hydrologic connection to surface waters of the state during the time of pesticide application. For calculating annual treatment area totals, –Count each pesticide application as a separate activity. Also, multiple treatments to the same area are considered as distinct pesticide application events. For example: – a 5-acre treatment area that is treated 4 times in one year equals 20 acres of treatment area, and –treating both sides of a ten mile ditch is equal to twenty miles of treatment area.
