## Abstract

We are amending 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. This action will allow for the interstate movement of these newly developed varieties without unnecessary restrictions.
