Methyl bromide (MB) or Telone (1,3-dichloro-propene or 1,3-D) is used for soil fumigation by the grape growers in central California, the United States, to control nematodes and other soil-borne pests. Regulations are being developed and modified to limit total fumigant emissions (including 1,3-D) in townships and require larger buffer zones to reduce potential exposure to farm workers and bystanders. More stringent regulations on fumigant emissions are likely to be issued in the near future to protect air quality. However, no emission information is available in the literature on 1,3-D and chloropicrin (CP) volatilization losses under grape replant situations.
