1.After regulation 22 of the Quarantine (Plants) Regulations the following regulation is inserted:—

Fumigation of cotton.

“22a. Where any imported raw cotton (lint and linters), other than cotton grown in the United States of America, is ordered into quarantine and conveyed to a quarantine station, it shall, while detained at that quarantine station, be fumigated in the manner prescribed by sub-regulation N of regulation 30 of these Regulations.”.

Fumigation.

2.Regulation 30 of the Quarantine (Plants) Regulations is amended by omitting sub-regulation N and inserting in its stead the following sub-regulation:—

“N. Vacuum Fumigation.—(1) Vacuum fumigation shall be carried out in accordance with such one of the methods prescribed in paragraphs (2) and (3) of this sub-regulation as is applicable in the circumstances.

(2) Bulbs shall be treated for not less than 90 minutes and not more than two hours in a vacuum of 29 inches with carbon disulphide at the rate of 25 pounds per 1,000 cubic feet.

(3) Other goods shall be treated in a vacuum of 27 inches with—

(a) carbon disulphide at the rate of 20 pounds per 1,000 cubic feet for not less than one hour; or

5584.—6/7.12.1937.—Price.—3d.

(b) carbon disulphide combined with carbon dioxide in the proportions of 5 pounds of carbon disulphide to 15 pounds of carbon dioxide per 1,000 cubic feet for not less than two hours; or

(c) hydrogen cyanide gas, prepared and used in accordance with

  one of the following methods, for not less than one hour:—

First Method.—Dissolve sodium cyanide (50 per centum cyanogen) at the rate of 100 pounds in 21 imperial gallons of water. Unless the goods to be treated are nursery stock, use 60 fluid ounces of this solution with 24 fluid ounces of sulphuric acid (commercial 60 degrees Beaumé, approximately 93 per centum pure) and 24 fluid ounces of water for each 1,000 cubic feet. Where the goods to be treated are nursery stock, use 25 fluid ounces of the cyanide solution with 10 fluid ounces of sulphuric acid and 10 fluid ounces of water for each 1,000 cubic feet.

Second Method.—Inject 432 cubic centimetres (or, where the goods to be treated are nursery stock, 180 cubic centimetres) of liquefied hydrogen cyanide for each 1,000 cubic feet. All the liquefied hydrogen cyanide shall be injected by the time the gauge registers zero and the period of treatment shall be reckoned from that time.

Third Method.—Use an impregnated preparation which evolves hydrogen cyanide gas in vacuo allowing an excess weight of 10 per centum over the amount calculated to yield the quantity of gas as required by the First Method; or

(d) ethylene oxide at the rate of 5 pounds per 1,000 cubic feet for not less than one hour, or, if preceded by or combined with carbon dioxide, 3 pounds of ethylene oxide to 27 pounds of carbon dioxide, for not less than two hours.

(4) Full particulars of the treatment shall be recorded, including the vacuum obtained, the pressure during contact with the gas, the period of contact, temperature, composition of fumigant and quantity used and treatment before and after fumigation.”.
