Disposing of the washing rinsates to non-cropped areas is a risky practice for the same reasons discussed earlier. From the
standpoint of practicality and economy, rinsing with clean water in the field at the site of application seems to be the most
preferred method of decontamination, since therinsatescan be added to the spray tank and further utilized or disposed of over
wide areas . Other methods of rinsate disposal such as flushing the tank in a barnyard or draining the “dilute”
material in a convenient place are illegal and they present a threat to surface and ground water, as well as other
parts of the environment.
Reed et al. (2000)
reported that most
farmers in three Nebraska counties applied leftover diluted
chemical residues or rinsates evenly on the field just sprayed.
