Residues of aldicarb and fenamiphos [parent compound, sulfoxide, and sulfone metabolites analyzed as sulfone and expressed as total aldicarb (TA) or total fenamiphos (TF)] in the roots, soil, leaves, and fruit from vineyards were determined with a gas chromatograph equipped with packed columns. Temik (aldicarb) granules at 5 kg/ha and Nemacur (fenamiphos) granules at 20 kg/ha were applied either in scatter over the entire area (broadcast) or in 20-cm bands on either side of the rows of vines. No residues of TA or TF were present in any of the samples taken before application, showing that there were no residues from previous treatments. Twenty-eight days after application no TA residues were present in any soil samples at the depths sampled; TF residues were, however, still present in the 30-60-cm layer. In spite of residues of TA and TF in the soil, all fruit samples contained less than 0.01 mg/kg of TA and less than 0.02 mg/kg of TF at harvesting. Band application in contrast to broadcast application gave rise to a lower maximum leaf concentration of TA and a higher maximum leaf concentration of TF. The control samples were without any TA or TF residues. © 1986 American Chemical Society.
