Soil-binding adjuvants can reduce herbicide loss via runoff* [Full subscriber]

Abstract         Concentrations of a range of pesticides exceed water quality guidelines throughout the year in many fresh and estuarine water bodies of the Great Barrier Reef catchment.  To mitigate its impact and maintain its productivity, the Australian sugar industry is looking at innovative options to reduce the movement of herbicides off site.  Three oil-based adjuvants (Grounded® applied at 3 L/ha, Atpolan® soil Maxx applied at 0.4 L/ha and Ad-HereTMapplied at 1 L/ha according to their respective labels), a terpene-based adjuvant (Flextend® applied at 1.2 L/ha), and a polyol-based adjuvant (Watermaxx®2 applied at 9.35 L/ha), were tested on bare soil and…
