Assessment of the commercial application of a methyl bromide and carbon dioxide mixture for the control of grain insects



Assessment of the commercial application of a methyl bromide and carbon dioxide mixture for the control of grain insects



Plant Protection Quarterly 1(2): 51-56



A commercial method of applying methyl bromide and carbon dioxide mixtures to wheat silos in order to control grain insects has been developed. Carbon dioxide from a road tanker is passed through a vaporizer in which it is mixed with air. A gas mixture containing 60% carbon dioxide is piped to the base of a silo where methyl bromide is bled into the gas stream. In trials in 2000-t wheat silos, the interstitial and headspace air was gradually expelled by the gas mixture. When the mixture was detected at the top of the silo, the gas purge ceased and the silo was sealed. This method gave good gas distribution which was subsequently maintained by a small recirculation fan (37 W). It was found that when a concentration .times. time product (ct) of 50 g h-1 m-3 of methyl bromide was achieved, all stages of Tribolium castaneum, Rhizopertha dominica, Sitophilus oryzae and S. granarius were killed. Fumigation could be completed within 24 h using only 23 kg of methyl bromide in a 2000-t sili, 1/3 of the minimum dose currently recommended for commercial fumigation. Bromide residues on the wheat were much lower and the ventilation time required to reduce methyl bromide concentrations to the threshold limit value of 5 ppm was much shorter (by more than 24 h) than for a commercial treatment with methyl bromide alone.
