Carbaryl, chlorobenzilate, dimethoate, and trichlorfon insecticide formulations were applied at the highest recommended dosages to California lemon and orange trees. Dislodgable foliar residues are herein reported to provide a basis for determining potential exposures of agricultural workers who come into continuous and prolonged contact with the treated foliage. Fruit was sampled about 60 days postapplication, and the edible portions (pulp) of the fruit after rind removal were analyzed for the presence of persisting residues; analytically significant pulp residues were absent. © 1979, American Chemical Society.
