Sucker growth, yield, and fruit quality was monitored for two years following treatment. NAA at 1.0% gave satisfactory control of sucker growth for three seasons with no deleterious effects on vine growth, yield, and quality of fruit. Lower concentrations were effective for two seasons following application. ER -
