Hexazinone, a systemic herbicide registered for use on wild blueberries in 1983 is credited with increasing Maine's wild blueberry crop by three-fold over a 10 year period, while also increasing overall fruit quality. Unfortunately, the high water solubility of hexazinone gives it a high leaching potential. This solubility factor is exacerbated by the sandy soils where wild blueberries are commonly propagated. In 1991 a routine screen for pesticides used in blueberry agriculture revealed traces of hexazinone in water samples from property formerly used for blueberry production. This discovery has led to the development of solid phase extraction (SPE) and ...
