Methyl Bromide, an effective and economical fumigant, has 
proved itself in many difficult fumigations. It possesses unusual 
chemical properties which make it especially useful to seed 
dealers and growers. 
VAULT FUMIGATION 
Methyl Bromide is especially well adapted for use in the fumi- 
gation vault. Its great power of penetration permits it to reach 
the center of every bag in the vault load. It is capable of killing 
insect eggs as rapidly as the more active stages, thus com- 
pletely eliminating insect life with a single fumigation. Its 
action is rapid so that the exposure period need not exceed 
twelve hours. By increasing the dosage, it may be cut to four 
hours. Simple inexpensive equipment permits its application 
from outside the fumigation chamber so that with reasonable 
precaution no gas mask is needed except in the case of pos- 
sible emergency breakage of equipment.
