APHIS Seeks Comments on the Release of the Japanese Knotweed Psyllid
USDA’s Animal and Plant Health Inspection Service (APHIS) has assessed the potential environmental impacts associated with releasing the Japanese knotweed psyllid (Aphalara itadori) to biologically control Japanese, Giant, and Bohemian knotweeds (Fallopia japonica, F. sachalinensis, and F. x bohemica) within the contiguous United States.
These knotweeds are significant invasive weeds. Based on their thorough analysis, APHIS scientists have determined that the release of this psyllid would not have a significant impact on the environment. We are making the environmental assessment available to the public for review and comment for a 30 day period that ends on June 27, 2019. APHIS will review and respond to all comments received. If the public does not raise any significant concerns, APHIS will issue a Finding of No Significant Impact (FONSI) and begin issuing permits to release Japanese knotweed psyllid into the environment.
