The wine industry in southern Brazil is affected by late frosts that cause losses in earlier varieties such as 'Chardonnay' and 'Pinot Gris'. The aim of this study was to develop a new form of application of growth regulators to delay budding of 'Chardonnay' and 'Pinot Gris'. The experiment was conducted in a commercial vineyard in Vacaria, RS, (28°32'11" S and 50°50'04" W and 972 m). The branches were pre-pruned with four buds, for the application of the products. The treatments were applied to the winter bud with concentrations (mg L -1 )
