How should you manage pesticide application around ornamental water features to protect aquatic life?

• A. Apply directly into water features for better efficacy.
• B. Ignore buffer zones if wind is light.
• C. Maintain required buffer zones; avoid runoff; use drift-reducing nozzles; follow label restrictions.
• D. Use high drift nozzles to increase coverage.

Answer: (C)

Protecting aquatic life around ornamental water features depends on preventing pesticide movement into the water. The best approach is to keep the prescribed buffer distance between treated areas and the water, prevent runoff from entering the feature, use drift-reducing nozzles to minimize spray that could drift onto the water, and always follow all label restrictions for rates, timing, and methods. Pesticides can be toxic to fish, amphibians, and other aquatic organisms even at low concentrations, so avoiding direct application into water features and controlling how the spray moves are essential. Directly applying into water features is not appropriate and is often prohibited. Ignoring buffer zones, even with light wind, still poses a drift and runoff risk, and using high-drift nozzles increases off-target movement toward the water. Following these practices protects aquatic life and keeps applications compliant.
