Black Stem Rust; Additions of Rust-Resistant Species and Varieties
On September 5, 2017, the Animal and Plant Health Inspection Service published a direct final rule. The direct final rule notified the public of our intention to amend the black stem rust quarantine and regulations by adding 15 varieties to the list of rust-resistant Berberis species and varieties and 2 varieties to the list of rust- resistant Mahonia species and varieties. We received two comments, which are addressed in this document.
Availability of an Environmental Assessment for the Biological Control of Yellow Toadflax
We are extending the comment period for our draft environmental assessment relative to the control of yellow toadflax (Linaria vulgaris), which considers the effects of, and alternatives to, the field release of a stem gall weevil, Rhinusa pilosa, into the continental United States for use as a biological control agent to reduce the severity of yellow toadflax infestations. This action will allow interested persons additional time to prepare and submit comments.
