Almond - Leaf Scorch

Direct copy from UC IPM website to word document Statewide IPM Program, Agriculture and Natural Resources, University of California All contents copyright © 2009 The Regents of the University of California. All rights reserved. Almond leaf scorch appears as a marginal scorching of leaves that begins as early as June and continues to develop during summer. A golden yellow band develops between the brown necrotic edge and the inner green tissues of the leaf. Disease symptoms may appear first on one branch or a portion of one scaffold. As years go by, more and more of the tree is affected until the whole canopy is involved. Another name for this disease, golden death, describes the golden yellow color of the canopy of a severely infected tree. Infected trees bloom and leaf out later than healthy trees, are stunted, less productive, and have reduced terminal growth. Trees with almond leaf scorch usually survive for many years.
