Four Israeli soils (Hula, Newe Ya'ar, Sa'ad, and Sharon) were studied in an attempt to identify factors affecting the behavior of bromacil in a soil environment. Adsorption studies were performed by batch slurry experiments. Bromacil phytotoxicity was studied by bioassay with black mustard. Soil thick layer chromatography was used to determine bromacil leachability in the various soils. The experiments showed that the soil organic matter content governed bromacil adsoprtion, phytotoxicity, and leachability in the various soils. -from Authors
