Methyl bromide is a soil fumigant, commonly used on fruits and vegetables to control
soil-borne pests. It is also a Class I ozone depleter. Recent scientific evidence suggests that
methyl bromide is 60 times more effective than CFCs at detroying ozone. The U.S. is
unilaterally phasing out its production and use of methyl bromide by January 1, 2001.
Mexico also uses methyl bromide production on horticultural crops, particularly in Baja
California. As a signatory to the Montreal Protocol, it is presumably following the agreement
that use will be frozen in 2002 and there will be a complete phase out by 2010.
