General description
Bromomethane (methyl bromide) is the most effective soil fumigant for killing plant pests, its use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. The bimolecular nucleophilic substitution (S(N)2) reaction of methyl bromide and OH- in aqueous solution has been investigated using a multilayered-representation quantum mechanical and molecular mechanics methodology.

Despite generally being considered the most effective soil fumigant, methyl bromide (MeBr) use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. However, a large amount is still currently used due to Critical Use

Although ozone-depleting methyl bromide was destined for phase-out by 2005, it is still widely applied as a consequence of various critical-use-exemptions and mandatory international regulations aiming to restrict the spread of pests and alien species (e.g. in globalized transport and
