In 193S methyl bromide was tested experimentally as a means of 
ground squirrel control. The results were encouraging, and further 
studies are planned, especially as to practical means for handling 
the gas. If suitable methods are developed, its use will be limited, 
for a time, to follow-up operations, since the cost of methyl bro- 
mide is as yet too high to permit its use in regular control work.

Preliminary tests of methyl bromide as a nematocide, Helminthol, 
Soc. Wash. Proc. 7: 94-96. 1940. 
Methyl bromide appears to be an effective soil nematocide for 
use against the root-knot and free-living nematodes. Satisfactory 
results were obtained in preliminary trials with 80 cc, to treat a 
layer of soil 15 cm. thick in a fumigation box of 1 cu. m. capacity. 
Fair results were obtained with 1.5 pounds to treat 225 square feet 
of soil, when the chemical was applied through hollow-tile lines 
buried 18 inches under the soil and 18 inches apart. There was 
some evidence that methyl bromide also controls fungi and bacteria, 
in the soil, but an attempt to elimate root-knot nematodes ^from 
tomato plants was unsuccessful. Nematodes in the larger galls 
were not killed, and most of the plants were killed or severely 
injured.

These chemicals are very soluble in lipoids, and thus consti- 
tute poisons for the organism and particularly for the nervous 
system. The disturbances which they cause in the organism are de- 
scribed.

Fumigation with methyl bromide was effective in killing Japan- 
ese beetles in green beans packed in hampers and in killing larvae 
of the beetle infesting strawberry plants packed, with soil on 
their roots,- in cratos. It also gave promise of being a good green- 
house fumigant, giving nearly complete kills of three varieties of
