STUDIES ON FUMIGANT 'ETHYLENE OXIDE' (4). STUDIES ON THE FUNGICIDAL AND INSECTICIDAL PROPERTIES OF VARIOUS MIXTURES OF ETHYLENE OXIDE AND METHYL BROMIDE
Abstract
When methyl bromide is added to ethylene oxide, the fungicidal effect is the same as or better than ethylene oxide alone. The effect is slightly lower in the case of methyl bromide alone. Thus, the addition of methyl bromide not only prevents the explosion of ethylene oxide, but also reduces the amount of ethylene oxide required for eliminating fungi. On the other hand, the fibroid bacilli are completely eliminated with fumigant 200 g/1.5 cu m. Insecticidal speed of ethylene oxide is significantly increased by the addition of methyl bromide. Fungicidal power of methyl bromide is less than ethylene oxide, but the speed of penetration into the fumigating material is higher. Explosion limit of ethylene oxide 25% : methyl bromide 75% is 8-22% and corresponds to 440 g-1.22 Kg/1.5 cu m. On the one hand, since the effective fungicidal amount is far below the lower limit of explosion, an explosion and fire hazard are considered practically nonexistent.
