  • Spatially Targeted Drone Carries Biocontrol Weevil to Hard-to-Reach Patches of Mile-a-Minute Weed

    • 2020

    • USDA. Forest Service.

    • Inadvertently introduced in the northeastern United States in the 1930s, mile-a-minute weed is a highly aggressive invasive plant that is replacing native species in many areas of the Nation. While a biocontrol agent has been identified, finding and reaching dense patches of mile-a-minute weeds has been a problem for land managers. The solution may be drones carrying environmentally friendly pods packed with tiny weevils.
