APHIS Extends Comment Period for Environmental Assessment for the Release of the Japanese Knotweed Psyllid to Biologically Control Japanese, Giant, and Bohemian Knotweeds

Washington, D.C., July 10, 2019 – 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 a thorough analysis, APHIS scientists have determined that the release of this psyllid would not have a significant impact on the environment.

In response to stakeholder requests for more time, we extended the comment period, ending on August 26, 2019. APHIS will review and respond to all comments received. If the public does not raise any significant concerns, we will issue a Finding of No Significant Impact (FONSI) and begin issuing permits to release Japanese knotweed psyllid into the environment.
