ETHYLENE DIBROMIDE FUJiGATION APPROVED AS A CONDITION FOR CERTIFICATION OF MANGCES UNDER PUERTO RICAN FRUIT AND VEGETABLE QUARA'.TINE NO. 58

Pursuant to the authority conferred upon the Chief of the Bureau of
Entomology and Plant Quarantine by sections 301.58-2 and 301.58-3 of the
regulations supplemental to Puerto Rican Fruit and Vegetable Quarantine No. 58 (7 CFR 301.58, 301.58-2 and 301.58-3), issued under sectiou 8 of
the Plant Quarantine Act of 1912, as amended (7 U.S.C.161), and being
satisfied from the evidence submitted that the movement from Puerto Rico
of mangoes which have been fumigated in accordance with the procedure outlined below will not result in the dissemination of injurious insects likely
to affect such fruit, the following administrative instructions are hereby
issued, to appear as 301.58-3d in Title 7, Code of Federal Regulations:

5 301.58-3d Administrative instructions authorizing the movement of
mangoes front Puerto Rico aftr approved fumirations (a) Removal from prhib ited status. Mangoes that have been subjected to the approved treatment
provided for in paragraph (b) of this section are hereby removed from the prohibited status established by 301.58-2, and are included in the list
for which movement from Puerto Rico into or through any other Territory,
State, or District is authorized by ( 301.58-3.

(b) Approved treatment. (1) The approved treatment shall consist of
fumigation with ethylene dibromide in an atmospheric fumiption vault, which vault and its equipment have been approved for that purpose by the Bureau of Entomology and Plant Quarantine. The dosage shall be aonlied at the rate of
6 ounces of ethylene dibromide per 1,000 cubic feet of space, including the load. The xposure shall be of 2 hours duration, calculated from the time
that all of the fumigant has been introduced into the chamber. The air and fruit temperature shall be 50. F. or above. The ethylene dibromide must be
applied in the liquid state and volatilized within the sealed fumigation
chamber by direct contact with a highly heated metal surface over an electric
hot pl.te or other suitable heating medium. The gas shall be circulated
within the chamber continuously for the 2-hour period by an electric fan or
blower.

(2Y7Mangoes to be fumigated may be ps-.cked as for shipoing in crates with shredded packing material. When fruits are individu-11y wrarped in
paper the wrappings must be removed before funig-tion. Then loaded in the
fumigation chamber the crates or other containers shall be separated at least 2 inches on all sides by wooden str1 s or other means. The chamber shall not
be loaded to more than 50 percent of c-pecity.

(3) Both the fumiction and the subsequent handling of the mangoes preparatory to shipment must be under supervision of a plant quar-ntine inspector of the Bureau of Entomology and Plant ('ou-rntine. Furipated mangoes

must be safeguarrded against reinfest tion during the period prior to shipment in a manner sntisf.ctory to the inspector. Certific-.tion of mangoes for shipment will be based on both the treatment and compliance with the prescribed post-treetment s fegu-.rds.

(4) All costs of treatment "nd prescribed post-treatment safeguards, other th.n the services of the supervising inspector, shall be borne by the owner of the mxangoes, or his represent-tive.

(5) Thile the prescribed treatment is judged from experimental
tests to be safe for use with ma.ngoes, the Department assumes no responsibility for any dimnge sustained through or in the course of treatment.

This section shall be effective October 1, 1951.

(Sec. 8, 37 Stat. 318, as amended, 7 U. S. C. 161; 7 CFR 301.58-2 and 301.58-3)

The purpose of these instructions is to authorize the interstate movement frcn Puerto Rico under certification of mangoes that have been given an approved fumigation treatment. Heretofore such movement has been prohibited. This newly authorized treatment therefore removes a restriction previously imposed. In order to be of maximum benefit to mango shipprs, .'the nowly authorized procedure should be made available as soon as possible. Therefore, pursuant to section 4 of the Administrative Procedure :Act (5U. S. C. 1003) it is found upon good cause that notice 2nd public procedure on the foregoing administrative instructions are unnecessary, impr-cticable, and contrary to the public interest, and since those instructions relieve restrio.tions they may properly be made effective under snid section 4 less than thirty days after their publication in the Federal Register.
