The effect of carbon bisulphide, methyl bromide and hydrogen phosphide (phostoxin tablets) on the germination of certain seed varieties was tested. Results obtained could be summarized in the following: (1) Doses of 20 gr. of methyl bromide, 200 cc of carbon bisulphide for a 24-hour period of exposure and 2.5 tablets of phostoxin for a 3-day period of exposure for a cubic metre in all cases did not affect materially the percentage of germination of Early American, Hybrid 17 and Hybrid 186 varieties of corn, Giza 66 and Giza 68 varieties of cotton. (2) While Giza 155 variety of wheat was not affected when using carbon bisulphide or phostoxin at the rates mentioned, it was significantly badly impaired when using methyl bromide. (3) Higher doses or higher moisture contents in treated seeds might result in proportional increase in the deleterious effect of seeds. (4) Higher doses or higher moisture contents might result in varietal difference.
