| Abstract: | Recent advances in fumigation technique in the USSR are reviewed. The problem of fumigation in containers is being approached by introduction of the gas through air-holes. Mixtures of methyl bromide with carbon dioxide are being used increasingly against storage pests, and allow lower dosage rates and safer application conditions. Recent experience on quarantine fumigation of potato tubers against Phthorimaea operculella is reviewed, and finally research is reported on neutralizers and absorbents of methyl bromide used to facilitate degassing. |
