Vitazyme on Grapes – 2011, Chile

This Flame Seedless table grape trial in Chile proved that Vitazyme greatly improved the early coloration and maturity of the grapes, using two 2 liter/ha applications before and at grape coloring, Ethrel provided a significant improvement as well, but not nearly the advancement in harvest as did Vitazyme.
Percent of total grapes, first harvest

Vitazyme ............................. 82%

Ethrel .................................. 55%

Control ................................ 27%

Vitazyme increased the percentage of grapes in the first harvest by 195%, compared to 100% for Ethrel, showing the superiority of Vitazyme to advance coloration and maturity, and thus capture higher market prices versus untreated grapes. Besides, Vitazyme prevented many splits of the grapes compared to the Ethrel and control treatments, and the sugar of the fruit was about 1.25 Brix higher with Vitazyme. Because the product was applied late in the season there was no increase in yield; early applications would have boost- ed yield besides enhancing coloration and earlier marketability.
