Which group is highly toxic to Flumioxazin?

Explanation:
Aquatic invertebrates are the most sensitive to Flumioxazin. This herbicide works by inhibiting a plant enzyme (PPO), but the same mode of action can disrupt aquatic invertebrates more readily, even at lower concentrations. Organisms like Daphnia and other small crustaceans often show adverse effects first, which is why water-quality testing and labeled aquatic-use restrictions emphasize protecting these species. Birds, mammals, and even fish typically tolerate higher exposures before effects become severe, so the strongest, most consistent toxicity observed for Flumioxazin is in aquatic invertebrates.
