If a pesticide label states it is harmful to bees, what should applicators do?

When a pesticide label indicates that it is harmful to bees, the appropriate action for applicators is to avoid application during blooming periods when bees are active. This approach is crucial because bees are primarily foraging for nectar and pollen during these times, significantly increasing their exposure to harmful chemicals. Protecting bee populations is essential, as they play a vital role in pollinating crops and maintaining biodiversity.

Applying pesticides when bees are less active—such as in the evening—is an option that may reduce direct exposure, but it does not address the risk posed when the pesticide is applied to blooming crops that are active during the day. Mixing pesticides with bee-safe sprays may reduce toxicity, but it can lead to inconsistent results and does not guarantee safety. Using pesticides only on non-blooming crops is a preventative measure, but it is not always feasible or practical for all agricultural practices, thus making it less ideal depending on the cropping system and regional practices. Therefore, avoiding application during blooming periods when bees are active is the most effective and responsible strategy to protect these essential pollinators.
