Prior to the application of any pesticide labeled as toxic to bees, an applicator is required by rule (IAC 21-45.31(206)) to notify all owners of registered beeyards within a 2-mile radius of the site of application. Notification is required at least 24 hours and no more than 72 hours prior to the application. This notification enables beekeepers to move or otherwise protect the bees.
