Interpretive Summary:

Technical Abstract: Over the last five decades, agricultural producers have relied heavily on fumigation to control soil-borne pests. In the current search for replacements for methyl bromide (MeBr), chemical alternatives appear to be an integral part of the short-term solution. The future use of fumigants must become more efficient and have fewer negative environmental impacts, or they too will become susceptible to adverse environmental regulation. After 2005, only a few registered chemical fumigants will remain: 1,3- dichloropropene (1,3-D or Telone), chloropicrin, and methyl isothiocyanate (MITC) and two under considered for registration: methyl iodide and propargyl bromide. This is a significant reduction in available materials compared to earlier years and demonstrates that all fumigants share intrinsic properties that cause environmental problems. This has lead to a research project to develop tools that allow the prediction of the pathogen ncontrol and total emissions after soil fumigation. The project involves th development of a mathematical model to describe fumigant movement and pathogen control.
