Vitazyme on Grapes – 2009, Chile
This Sygenta test of Vitazyme, at 1.0 and 1.5 liters/ha applied twice — once before and once after verasion — revealed that the product did little to alter the sugar (brix) content of the fruit at harvest, but enhanced maturity of the fruit, especially at the 1.5 liters/ha rate. The 1.5 liters/ha rate increased harvestable bunches by 7.76% at the last recorded harvest date. Fruit color was also enhanced with Vitazyme, the desired green color being 19.91% higher at the 1.5 liters/ha rate than for the control; the 1.0 liter/ha rate gave to 12.99% increase. The greater percentage of geen fruit was likely due to the product’s chlorophyll enhancing effect throughout the plant, including the fruit skins. Vitazyme is shown to be an excellent adjunct to table grape production in Chile, enhancing maturity as well as grape color.
