D. Restrictions.

1. Certification Required. Except as provided in paragraphs (2) and (3) below, articles and commodities covered are prohibited entry into the State of California from the area under quarantine unless each shipment or lot is accompanied by a certificate issued by an authorized agricultural official of the state of origin, evidencing field treatments and inspections of the growing crop or post harvest treatment for the pests quarantined against as prescribed by the Department. The certificate shall specify: treatment; the kind and quantity of the commodity constituting the lot or shipment; the initials and number of the railway car or license number of the truck or trailer; the name and address of the shipper and consignee; and the date issued.

FLORIDA

APPENDIX A 11/08/88

The Florida Department of Agriculture reports that they do not have southwestern corn borer in Florida. They do, however, have both southern cornstalk borer and sugarcane borer in Florida. Florida Department of Agriculture certificates which mention southern cornstalk borer and sugarcane borer, but make no mention of southwestern corn borer, meet the requirements of this quarantine and may be accepted. The necessary treatment will eliminate all three pests.

APPROVED POST HARVEST TREATMENTS

APPENDIX B 10 - 24 - 13

Sugarcane Treatments

The following post harvest treatments for certifying sugarcane for entry into California have been approved by the Secretary:

Cold treatment: The freezing of sugarcane stalks for 72 hours at -10^oC is considered an approved post harvest treatment for the sugarcane borer (Diatraea saccharalis).

Hot water dip: Dip sugarcane stalks in water heated at 52^oC (125.6^oF) for 20 minutes. During the entire treatment, the water must be continuously agitated in order to maintain temperature equilibrium. Timing of the treatment period should not begin until the temperature of the water has been restored to treatment temperature after cane introduction. The average size diameter of the canes should not exceed 46 mm. For larger diameter size canes, the pulp temperature must reach 49.8^oC (121.6^oF) within a 20 minute period.

Freezing treatment: sugarcane must be maintained at 0°C for at least 24 hours and chipped into pieces one inch long or finer and then dried at 60°C for five days.

Shipments of sugarcane treated in this manner may enter California if accompanied by a certificate issued by an agricultural official of the state of origin affirming that the shipment was treated in an approved manner and complies with quarantine requirements.

Shelled Corn Treatments

Methyl bromide plus chloropicrin fumigation (SLN Reg. No. CA890047, Brom-O-Gas; contains 0.5% chloropicrin, EPA Reg. No. 5785-8), chamber at NAP, or tarp. The methyl bromide fumigation schedules listed in the USDA/APHIS/PPQ Treatment Manual, Section VI, T302(b) and T302(c), are not registered for use in California. Before using these schedules the California Department of Food and Agriculture must be consulted. Prior to authorized treatment, arrangements should be made to provide post-treatment inorganic bromide residue samples to ensure the tolerance of 50 ppm has not been exceeded.

Shelled grain may be certified under (D.1 and 2) provided it has passed through a ½-inch or smaller mesh screen prior to loading and is believed to be free of stalks, cobs, stems, or portions of plants or fragments capable of harboring larvae of corn borers, and , further, that the car or truck has been found to be free of any such host plant fragments at the time of loading (see Section 3263 of Title 3 of the California Administrative Code pertaining to the European Corn Borer External Quarantine, (E.2.a and b) and Appendix C (11-22-93).
