Vitazyme on Apples – 2013-Brewster, Washington

This Washington State Gala apple trial revealed that Vitazyme improved apple quality above Stimplex seaweed extract, with four applications of each at recommended rates. There were meaningful improvements in apple size (1.6%), weight (2.5%), pressure (0.9%), and brix (0.9%-point), but the improve- ment in fruit grade was remarkable, with many more Premium apples (23%) and far fewer USXF apples (- 19%) with Vitazyme. Though official yield data was not measured, both the researcher and the grower noted that the younger trees on the Vitazyme treated half of the block yielded several bins more than did the younger trees on the Stimplex half.
