Feedback & Results
May 13: Thicker stems on new shoots while shoot selecting in and near areas that received ground application.

Aug 11: Noticed powdery mildew in row 1 of Riesling, air blast application on Aug 18, Aug 21 noticed the mildew was dead and no longer spreading. Discontinued use of other products to control mildew and only used ACF for the remainder of the season.

Areas that only received ACF did not have any mildew this season where as the areas that did not receive ACF until late season did show signs of mildew. What was easily identified was the overall plant health, showing up through increased growth and vigour, even in the poor plants.

“We treated one vineyard with ACF and the other was treated with our usual products, in the treated vineyard we found almost no powdery mildew while in the other vineyard it was pretty standard with a bit of mildew throughout.”

YIELD INCREASE on Pinot Noir Vineyard:
17+% increase in yield in the vineyard that received the ground applications. Cluster formation was more consistent where ACF was applied.

YIELD INCREASE on Riesling Vineyard:
2020: 3.89 tonnes increased in 202, after ACF-SR application, to 5.9 tonnes
