Zinfandel grapevines were treated at the rate of 100 mg/L and at twice that rate (200 mg/L) with 1-naphthaleneacetic acid (NAA) to control the secondary crop. Total NAA residues, including the two major conjugates (NAAsp and NAGlu), were determined on the harvested grapes by high-performance liquid chromatography. Total NAA residues ranged from approximately 6 ppm at application to 0.22 ppm 126 days after application, and conjugation products ranged from 0% to 91% between application and harvest. Treated grapes were processed into wine. For the 100 and 200 mg/L treatments, the total NAA residues were respectively 0.12 and 0.21, 0.07 and 0.12, 0.12 and 0.24, and 0.07 and 0.12 ppm for crushed grapes, pressed juice, pressed pomace and bottled wine.
