ADMINIS TRATIVE INSTRUCTIONS
FUMIGATION OF ONIONS BY METHYL BROMIDE AS A CONDITION OF
CERTIFICATION OF ONIONS MOVING BY RFFRIGERATOR CAR FROM TH

(Approved July 14, 1939; effective July 19, 1938)

Regulation 5, Sec. B, paragraph (6) of the Japanese beetle quarantine (No. 49) authorizes the issuance of certificates for the interstate movement of onions via refrigerator car from the area listed in that regulation to points
outside the regulated areas between June 15 and October 15 when the onions have been fumigated in the car, when deemed necessary in thu judgment of the in.
spector -nd when the doors and hatches of the car have been tightly closed or adequately screened under the supervision of an inspector.

TREATMENT AUTHORIZED

The treatment described herein has been found to be effective against the Japanese beetle and such treatment is authorized as a basis for certific"A tion of onions moving to points outside the regulated areas between June 15 and October 15 via refrigerator car when such treatment is carried out under the
supervision of an inspector and in a manner satisfactory to him,

TREATMENT METHOD

Fumigation of onions in dry refrigerator cars with methyl bromide at a dosage of 2 pounds per 1,000 cubic feet of space, including the space occupied by the onions and bunkers of the cars, for a period of 2 hours, during which time the car shall remain tightly closed with the plugs in place in the ventilator hatches. The temperature within the car when fumigated shall be not less than 700 F. Provision shall be made for circulating the mixture of air and fumigant in the car for as long a time as is deemed necessary by the inspector. At the end of the fumigation period the hatches shall be opened, the plugs removed, screens placed in the hatch openings, and the car shipped under standard ventilation.

In authorizing the movement of onions fumigated according to the require. ments stated rbove, it is to be understood that no liability shall attach either to the United States Department of Agriculture or to any of its employees in the
event of injury.

Caution: Methyl bromide is a gas at ordinary temperatures. It is
colorless and practically odorless in concentration used for the fumigation of onions, It is a poison, and the operator should use an approved gas mask when exposed to the gas at concentrations used in fumigation, and when opening the hatches for ventilating the cars. The car should not be entered until it is well aerated.
