Mode of action (MoA)
Glyphosate-based formulations (GBFs) other than Roundup Custom and Halex GT were identified as non-genotoxic by the ML ensemble and the global evaluation factor (GEF) rubric.
Although the GEF clastogen call is +, the positive result was not repeated and so the call is reported as “equivocal.”
