EASY, EFFECTIVE WAY TO SAVE 
YOUR SEEDS 
METHYL, BROMIDE 

Dow Methyl Bromide saves your seeds from 
insect damage. Because of its rapid diffusion 
rate it penetrates throughout large warehouse 
stacks, killing, at one application, insects in all 
stages including the egg. 
Dow Methyl Bromide is economical, nonflam- 
mable and easy to apply and vent. It does not 
affect germination when used at normal recom- 
mended dosages and exposure periods. 
Through the use of a new plastic-coated tarpaulin 
perfected by Dow, individual lots of infested seed 
may be fumigated at outlying points, buying 
stations, retail stores, or loading docks. A tar- 
paulin not only serves as a portable fumigation 
vault, but provides maximum economy through 
a minimum of waste space. 
Dow Methyl Bromide 
is a safe, economical, 
and effective vault 
fumigant. it is intro- 
duced from outside the

the vapors. The dosage may be weighed out on a 
platform scale or measured in a specially de- 
signed applicator. Because of its rapid diffusion 
rate, the vault is quickly vented. 
Dow Methyl Bromide is particularly adapted to 
warehouse fumigation because of its ability to 
penetrate large warehouse stacks and give a 
complete kill throughout. 
It diffuses under its own vapor pressure at 
ordinary fumigation temperatures. It is easily 
applied. Simply seal windows, doors, and other 
openings, then distribute cylinders evenly 
throughout the warehouse. At the completion of 
the exposure period, it will rapidly dissipate 
through opened windows and doors. Write DOW 
for a seed fumigation folder giving detailed 
instructions on this ap- 
plication. 
Methyl Bromide is also 
an effective fumigant 
for flower bulbs. For

other fields write to
