Augmentation du risque sanitaire ou environnemental
BCS is submitting new information to PMRA related to Foramsulfuron Technical. This information is not necessarily a new adverse effect of the subject chemical, but is rather new information submitted for agencys own review and evaluation. The Study Report title is Lemna gibba G3 - Growth inhibition test with foramsulfuron OD 22.5 (22.5 g/L) under static conditions. The difference in the NOECs is likely due to the treatment level spacing factors used in test design. Testing with TGAI resulted in a lower growth rate EC50 vs. the current study foramsulfuron OD 22.5 growth rate EC50, giving no indication that L. gibba is more sensitive to the formulation than the TGAI. BCS believes this value has minimal impact on the risk assessment as formulations do not runoff as intact mixtures and should not be used to represent an aquatic exposure scenario as a result of runoff. Also, no direct applications of foramsulfuron to water bodies, TGAI or formulation, are allowed on the label.
