Abstract
OUR attention was directed by Dr. A. Graniti, of the Istituto di Patologia Vegetale of the University of Bari, to the observations of Grosclaude1 and Graniti2 that culture filtrates of Fusicoccum amygdali Del., the causative agent of a disease of the almond tree (Prunus amygdalus St.) common in Italy, exhibited phytotoxic activity. This manifested itself in bringing about the wilting of leaves on small branches of almond trees, such as occurs under natural conditions in the infected plant.
