Phytophthora Ramorum: Quarantine and Regulations
APHIS' first published regulation on P. ramorum since February 2002 was published in the Federal Register today (February 27, 2007). This rule mostly codifies the Federal Order issued in December 2004 that established restrictions on the interstate movement of nursery stock from nurseries in nonquarantined areas in California, Oregon, and Washington. The rule also incorporates all changes to the rule (SPROs) issued since 2002 most of which are updates to the host list. These rules are in effect NOW. Click here to view the rule.
The comment period is 60 days and comments may be submitted online. Comments are welcomed and encouraged. The comment period ends 30 April 2007.
