Residues of carbaryl in sugar maple sap obtained from trees sprayed at 2.24 and 5.58 kg/ha always were below the established sensitivity level of 0.1 ppm in both bucket and pipeline samples taken during initial flow, peak flow, and late flow periods. Sap fortified with 5 ppm carbaryl and boiled for 1 h lost a mean 64% of the initial residue; the last porlion was detected in the condensate.
