Abstract
Naphthaleneacetic acid (NAA) at 0, 0.25, 0.5, and 1.0% concentrations was applied in June, 1979 to the trunks of Vitis vinifera L. cv Sauvignon blanc for the control of sucker growth. 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.
