Foliar and drench applications of the plant growth regulator abscisic acid (ABA) were applied to 1-year-old potted Vitis vinifera 'Pinot Noir' and 'Cabernet Sauvignon' vines infected with Xylella fastidiosa, the bacterial pathogen that causes Pierce's disease (PD). A naturally occurring ABA and a synthetic ABA were applied, and both materials showed some effectiveness at increasing curing rates of PD-affected grapevines. Pinot Noir grapevines treated with the drench ABA treatments had… CONTINUE READING
