Methyl bromide; Bromomethane

Tradenames: Trade or common names of methyl bromide containing products include: Brom-o-Gas, Bromomethane, Celfume, Embafume, Haltox, MB, MeBr, Methogas, Profume, Terr-o-Gas, and Zytox.

Regulatory Status: Methyl bromide is a highly toxic compound in EPA Toxicity Class I. Labels for products containing it must bear the Signal Word DANGER. Methyl bromide is a Restricted Use Pesticide (RUP). RUPs may be purchased and used only by certified applicators.

EPA has expressed concerns and proposed restrictions on methyl bromide due to concerns over its potential to destroy ozone. Ozone-depleting chemicals fall within the scope of the Clean Air Act. Unlike FIFRA, the Clean Air Act does not contain a risk/benefit balancing process that would allow retention of essential or high benefit uses, nor does the listing and phase-out of ozone depleters depend on the availability of alternative products.

Chemical Class: Not Available

Introduction: Methyl bromide is chiefly used as a gas soil fumigant against insects, termites, rodents, weeds, nematodes, and soil-borne diseases. It has been used to fumigate agricultural commodities, grain elevators, mills, ships, clothes, furniture, and greenhouses. About 70% of methyl bromide produced in the U.S. goes into pesticidal formulations.

Formulation: Methyl bromide is chiefly used as a gas soil fumigant against insects, termites, rodents, weeds, nematodes, and soil-borne diseases.
