Methylisothiocyanate (MITC) and chloropicrin (CP) are alternatives to methyl bromide for soil fumigation. However, surface transport of MITC emission has been cited as the cause for seedling damage in adjacent fields at several bare-root forest-tree nurseries. Field experiments were conducted at nurseries in Wisconsin and Georgia to measure air emissions of MITC and CP after fumigation. Four tr...
OBJECTIVES To assess exposure of commercial application workers to the nematocide cis-1,3-dichloropropene (cis-DCP). METHODS The study was conducted during the annual application season, August to 15 November, in the starch potato growing region in The Netherlands. 14 Application workers collected end of shift urine samples on each fumigation day (n=119). The mercapturic acid metabolite N-ace...
In 1980-1983 small-scale tests were conducted and background information was obtalned to determine the feasibility of developing a quarantine treatment with methyl bromide (MB) for the codling moth (Cydia pomonella La) infesting in-shall walnuts. Some of the studies conducted at this time included basic dose mortality responses of diapausing and nondiapausing larvae, residue determinations and ...
