Packers of pears and apples equipped themselves with fumiga- 
tion apparatus to take advantage of a change in the standardiza- 
tion lav/, which allowed 5 percent of visible worms and 5 percent 
of invisible worms in the packed fruit provided methyl bromide 
fumigation was used.

In continued investigations 34 varieties of azalea plants were 
treated in winter, without being removed from their packing (wicker 
baskets or wooden packing cases), by vacuum fumigation with methyl 
bromide at the rate of 40 or 80 gm. per cubic meter for 2 hours. 
On the whole, the treatments had no injurious effects on the plants.

Fumigation with methyl bromide c- used no injury to azalea 
plants when used at 40 gm. per cubic meter for 1, 2, or 3 hours 
at reduced or atmospheric pressure, but gave irregular results at 
higher dosages, sometimes causing injury that was found to be due 
chiefly to impurities and which was always more severe at the 
bottom of the fumigating chamber.

Fumigation with methyl bromide gas proved very satisfactory 
for destroying Kcifcria lycopcr cicclla (^usck) in harvested toma- 
toes, and was also used against Listrodoros o bliquus Klug in 
celery. In cold weather, however, this fumigant was loss effec- 
tive than hydrocyanic acre gas except at much higher dosagos, 
which sometimes caused injury to plants, especially those with a 
noticeable oil content.
