Use

Soil/Plant. Degrades in soils and plants forming 1-naphthylamine and phthalic acid (Hartley and Kidd, 1987; Humburg et al., 1989). Residual activity in soil is limited to approximately 3 to 4 months (Hartley and Kidd, 1987).Chemical/Physical. Forms N-(1-naphthyl)phthalimide at elevated temperatures (Worthing and Hance, 1991). Naptalam will precipitate as the free acid in very acidic waters or in extremely hard waters (Humburg et al., 1989).
