Which formulation is most likely to cause bird kills among the options?

• A. All formulations have the same risk to birds
• B. Insecticide formulations that are grain-based are the most dangerous to birds
• C. DF formulations pose the highest risk to birds
• D. G formulation is most likely to cause bird kills among the options

Answer: (D)

Granule formulations pose the highest risk to birds because they are small pellets that stay on the ground where many birds forage for seeds and grain. Birds often mistake these granules for food and quickly swallow them, delivering the toxicant directly. This ground-level exposure makes granules more likely to cause bird kills than other forms, which may be less visible, less attractive to birds, or less likely to be ingested. So, among the options, the granule formulation is the form most associated with bird kills.
