Table 1.
Compound (name and/or code) | Persistence | Ecotoxicology |
---|---|---|
Fosetyl‐Al | Very low persistence single first order DT50 0.01–0.06 days (DT90 0.04–0.2 days; laboratory conditions at 20°C, 40–75% MWHC soil moisture) | Low risk |
Phosphonic acid | Moderate to high persistence single first order DT50 28–130 days and biphasic kinetics DT50 31 to > 1,000 days (DT90 91 to > 1,000 days; laboratory conditions at 20°C, 45–75% MWHC soil moisture) | Low risk |
Ethanol | Very low persistence single first order DT50 0.09–0.18 days (DT90 0.28–0.58 days; laboratory conditions at 20°C, 40–75% MWHC soil moisture) | Low risk |
DT50: period required for 50% dissipation; DT90: period required for 90% dissipation; MWHC: maximum water‐holding capacity.
