Phosphonic acid applied as a soil drench, a foliar spray or a trunk injection before infection prevented the development of cankers in almond and cherry trees inoculated with Phytophthora cambivora. Foliar applications of 2 g phosphonic acid/L in autumn and spring were an effective and practical treatment. Trunk injections were also effectively but in some cases caused severe leaf scorch and leaf drop.
