Technical Abstract: The soil fumigant, methyl bromide, is under intense scrutiny due to recent evidence which indicates that it may damage the stratospheric ozone layer. Due to the Clean Air Act, methyl bromide is scheduled for phase-out by 2001. As indicated in a recent report from The National Agricultural Pesticide Impact Assessment Program, there will be substantial adverse economic impacts on the agricultural community if the use of methyl bromide is restricted. This has prompted numerous scientists: to study the environmental fate of methyl bromide; to search for replacement chemicals and/or nonchemical alternatives; and to develop new methodology which improves containment of methyl bromide (or any alternative fumigant) to the treatment zone. An important part of this research is ensuring that adequate pest control is maintained. This presentation gives general background information along with some of the research questions that must be solved so that fumigants and other volatile pesticides can be used in a safe and environmentally-sound manner. Failure to do this could result in future restrictions being placed on these important agricultural chemicals.
