Area Under Quarantine. The entire states of Alabama, Arkansas, Florida,
Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Tennessee, and
Texas. C.
Articles and Commodities Covered. Sweet potato plants, vines,

Other Sweet Potato Tubers Grown, Packed, or Stored Within, or Shipped From the
Area Under Quarantine Admitted if Treated at Origin. Sweet potato tubers
grown, packed, or stored within, or shipped from the area under quarantine,
will be admitted into California provided they have been certified by an
authorized agricultural official of the state of origin as having been
treated (at owner's risk) for sweet potato weevil and were protected from
post-treatment infestation by sweet potato weevil. 4
Articles and Commodities Covered, Except Seed Sweet Potato for
Planting or Propagation. From a Noninfested County or Parish in the Area
Under Quarantine Admitted Under Certification of Origin. Articles and
commodities covered, if grown, packed and stored (if stored) within and
shipped from a noninfested county in the area under quarantine, except seed
sweet potato for planting or propagation, will be admitted into California
provided each lot or shipment is accompanied by a certificate of origin
issued by an authorized agricultural official of the origin state giving the
name and address of the shipper, number and kind of container in shipment or
lots, manner of shipment, and car initials and number if shipped by rail. The
certificate shall state that the lot or shipment originated in a noninfested
county or parish. 5.
Exception. Morning-glories from a noninfested county or parish in
the area under quarantine are admissible without a certificate of origin. IDENTIFICATION
OF TRUE YAMS APPENDIX
A 10-31-84 True
yams (Dioscorea spp.) are not restricted by this quarantine. It is
difficult to differentiate between true yam and sweet potato tubers using
color of skin and/or tuber flesh as the determining factors. Sweet potato
tuber flesh may be white, orange, red, or purple. The skin can be any of the
aforementioned colors and in addition may be yellow or orange brown. A
recent shipment of "Boniatos", thought to be true yams, were found
infested with sweet potato weevils. This indicates that tubers in trade
labeled as "Boniatos" are actually sweet potatoes. Since it is
difficult to differentiate between true yam and sweet potato tubers,
shipments of "Boniatos" should be rejected unless the tubers have
been certified at origin as being treated in an approved manner for sweet
potato weevil. To
determine if the tubers are true yams, cut one end of the tuber off so you
have a slice approximately 2 inches thick. Rub the freshly cut areas together
several times and gently pull apart. If strings of latex appearing gum are
found attached to both pieces, the tuber can be determined to be a true yam
and may be released. Additional
Infested Areas Appendix
B
The following areas are
considered infested with the sweet potato weevil. These should now be
treated as regulated areas. Articles and commodities covered should be
rejected under the Food and Agriculture Code Section 6461.5. Other
parts of the state are not covered and certification is not required. North

That portion of Brunswick County described as follows: "The

07-09-08 For the purposes of this quarantine, regulated articles certified
with colored tags, attached or placed in each container in the load, issued
by an authorized agricultural official of the origin state, indicating that
the lot or shipment originated in a noninfested county or parish is an
acceptable form of origin certification. |
