Abstract
RIPPER et al.1 have shown that the organophosphorus insecticide, octamethylpyrophosphoramide (‘Schradan’), when sprayed on leaves, is absorbed and translocated to other parts of the plant. Metcalf and March2 have demonstrated the tolerance to ‘Schradan’ shown by the honey bee. Using radioactive ‘Schradan’, containing phosphorus-32, we have examined the possibility of the unchanged insecticide being present in the nectar of flowers and afterwards appearing in honey.
