MB Methyl bromide fumigation, this is a potent pesticide linked to human health problems and ozone layer depletion. Methyl bromide fumigation kills invasive species like pine beetles. In 1987, the Montreal Protocol aimed to regulate the use of methyl bromide, along with multiple other chemicals found to impact the ozone.

The following is based on the authors summary. Insecticidal, chemical and plant-tolerance tests were carried out in 1936-41 to investigate the efficiency of methyl bromide in greenhouse and vault fumigation. Rapid evaporation of the fumigant was obtained by spraying the liquid or by heating it in a shallow pan, and slow evaporation by exposing it in the shallow pan at normal temperature.

Methyl bromide is used to control insects as a space fumigant in flour and feed mills and ship holds, as a product fumigant for some fruit and cereals, and for general quarantine purposes. Methyl bromide acts rapidly, controlling insects in less than 48 h in space fumigations, and it has a wide spectrum of activity, controlling not only insects but also nematodes and plant-pathogenic microbes.
