Mildly toxic by ingestion andinhalation. When heated todecomposition it emits very toxic fumes of NOx, POx, andNH3.
Soil. Fosamine is rapidly degraded to carbon dioxide by microorganisms in soil (Humburg et al., 1989). The reported half-life in soil is approximately 7 to 10 days (Hartley and Kidd, 1987; Worthing and Hance, 1991).
Plant. After a 2.5% application to multi?ora rose plant leaves, 19, 21, 22, and 43% of the applied amount was absorbed after 1, 4, 8, 16 and 32 days, respectively (Mann et al., 1986). Degrades rapidly in plants with a half-life of 2 to 3 weeks (H
Chemical/Physical. Fosamine-ammonium is stable as a dilute solution but decomposes in weak acidic media (Worthing and Hance, 1991), probably forming water-soluble salts.
