7. Provide supplemental information here

The studies conducted on the coformulation GF-3565 (florpyrauxifen-benzyl plus penoxsulam) cannot be directly extrapolated to florpyrauxifen-benzyl (Rinskor) alone because the formulation contains an additional active that can influence toxicity and biological effects. Therefore, toxicity values derived from the mixture do not accurately represent the effects of florpyrauxifen-benzyl alone.
