Many pesticides are hazardous to bees. Large numbers of bees may be killed by the application of pesticides while the bees are located in the orchard. Growers should arrange spraying programs so that pesticides need not be applied during the time bees are in the orchard. When this is not possible, notify the apiarist at least 48 hours in advance of spraying so he can remove the colonies from the area. The grower and apiarist should agree before spraying is conducted to a fee for temporary hive removal. Spraying a chemical with a low residual toxicity to bees, in the evening when bees are not foraging, may alleviate the need to remove the colonies.
