Abstract

Application of phosphonate compounds has been shown to be an effective preventive treatment for sudden oak death (SOD), caused by Phytophthora ramorum, in coast live oak (Quercus agrifolia Née) and tanoak (Notholithocarpus densiflorus Manos, Cannon & S.H. Oh). To test the effectiveness of these treatments in a natural setting, paired 400 m2 sections of mixed evergreen/tanoak stands were randomly designated as either treatment or control plots, and topically treated with Agri-Fos® systemic fungicide. The experiment included 36 field plots in six California counties, including nearly 700 tanoak trees
