WHITE-FRINGED BEETLE AD1 LNISTRATIVE INSTRUCTI ONS MODIFIED TREATMENT AUTHORIZED

Introductory Note.--Further investigational work has shown that it
is possible to kill all stages of the white-frined beetle by methyl bromide fumigation under partial vacuum applied :t a modified dosage or at a modified temperature under the dosage heretofore authorized. This work has also shown the practicability of applying these treatments to soil masses up to 16 inches in diameter, instead of the maximum 11-inch diameter required heretofore. The instructions in B. E. P. Q. 503, fourth revision, which became effective January 9, 168, are mIodified accordingly.

The description as to the size requiromnts of the soil masses has been somewhat reworded for the nurose of clarification.

E. P. Q. 503, fourth revision] is hereby modified effective May 6, 1942, to read as follows:

(2) Tthy1 bromide fumigation under partial vacuum. (i) Fi'igation under .partial vacuum equivalent to at least 24.5 inches of r:ercury may be done with a dosage of either 4 pounds methyl bromide per 1,00 cubic feet, including the space occupied by the commodity, with an exposure of 1 1/2 hours at a temperature of 70* F.; or a dosage of 3 pounds of methyl br -id e per 1,000 cubic feet for a period of 1 /2 hours at a temperature of 75' F. In either case the vacuum shall be maintained during the entire period.

(ii) The soil masses shall have a diameter of not more than 16
inches if spherical, or if not spherical the masses or pots shall be of such size that no point within them will be more than 8 inches from the nearest point on the surface.
