Title FST+PPC SL 840 (310+530 g/L): Toxicity to the single cell green alga Raphidocelis subcapitata Korshikov under laboratory conditions
Date 09-MAR-22
No
Increased health or environmental risk
The green algal study with FST + PPC SL 840 (310+530 g/L) met reportability criteria for Canada due to lower endpoints as compared to the previously reported green alga study with propamocarb. The lower endpoints do not affect the risk assessment for propamocarb as the level of concern was low for adverse effects to aquatic non-vascular plants. Additionally, the lower endpoint could be a result of either fosetyl (FST) or propamocarb (PPC) in the formulation however the likelihood for these active ingredients occurring together is very low as no combination products exist for Canada. Furthermore, there are no tank mixes possible with these individual active ingredients as each have a different GAP.
No
The EC50 and NOEC from this study are lower than the previously reported values. However, since PMRA does not use the algae NOEC in the risk assessment, there is no impact on the safety determination for propamocarb.
