Other claims from this paper (8)
- Intervention effect Bensulfuron methyl reduced growth in all tested species.
- Observation Isoetes japonica had the lowest intrinsic relative growth rate and the lowest susceptibility, with an ED50 of 21 g ha −1.
- Observation Duckweed relative growth rates were similar to those of ferns except Isoetes japonica, while duckweed ED50 values were higher.
- Observation Salvinia natans had a bensulfuron methyl ED50 of 1.1 g ha −1.
- Observation Marsilea quadrifolia had a bensulfuron methyl ED50 of 1.2 g ha −1.
- Observation Lemna minor had a bensulfuron methyl ED50 of 6.5 g ha −1.
- Observation Spirodela polyrhiza had a bensulfuron methyl ED50 of 3.2 g ha −1.
- Recommendation Bensulfuron methyl application and runoff are expected to adversely affect growth of Salvinia natans, Azolla japonica and Marsilea quadrifolia.
