Advancing Ripening of Crimson Seedless using potassium metalosate, deficit irrigation, and PGRs

Jul-Sep 2012 – Crimson Seedless Grape research in 2011 evaluated foliar potassium applied early in ripening (14 obrix) along with Ethrel and Protone applied from early- to late-ripening (14 obrix, 16 obrix, and 19obrix). Foliar potassium applied in combination with Ethrel at 14 obrix resulted in the greatest increase of fruit color (packable fruit). Compared to the untreated control, this combination increased the first pick by 103% and the total harvest by 37%
