The following counties are under quarantine for sweetpotato weevil pursuant to S.C. Code Reg. Ch. 27 Article 6: Beaufort, Berkeley, Colleton, Charleston, and Jasper.
The entire states of Florida and Georgia are under quarantine. Also, any areas in Alabama, California, Louisiana, Mississippi, North Carolina and Texas regulated by the plant regulatory agency of the state concerned are under quarantine.
It is very important for growers and consumers alike to follow the quarantine regulations and not move sweetpotatoes or sweetpotato plant material from a quarantined area into a non-quarantined area. This includes ornamental sweetpotato vines sold in the nursery industry. Not only is the pest destructive to sweetpotato production but its presence in an area can inhibit the marketability of sweetpotatoes from unaffected fields due to the risk of spreading sweetpotato weevil.
Sweetpotato certification in non-quarantined (green tag) areas is required by most other states and certificates can be obtained from Clemson DPI. Certification requires sweetpotato weevil trapping and inspections. If you are a grower wishing to produce sweetpotato transplant slips for sale or to move sweetpotato root crops across state lines, contact DPI for certification.
