3 These pesticides, although toxic to bees as foliage 

 residues or contact poisons, are not toxic to honey bees 

 when applied as granules on or in the soil. 



A This pesticide is not registered for use in the United 

 States. 



5 Field dosages have caused brood damage. 



6 The microencapsulated formulation of methyl 

 parathion, known as Penncap-M®, is highly toxic to 

 foraging bees, young hive bees, and brood. Overall, it is 

 13 times more hazardous to honey bees than emulsifiable 

 concentrate (EC) formulation. 



7 Mevinphos (Phosdrin*), naled (Dibrom*), and tepp 

 have short residual activity and kill only the bees con- 

 tacted at the time of treatment or shortly thereafter. They 

 are usually safe to use when bees are not in flight; they 

 are not safe to use around colonies. 



6 Dosages of sabadilla are usually low enough to be no 

 problem. Do not apply sabadilla to open flowers that are 

 visited by bees.
