Brown Rot Blossom Blight is a common and potentially destructive disease of stone fruit trees, including cherry, plum and peach trees, as well as ornamental flowering trees such as weeping cherry and flowering plum trees.
When a tree is infected with Brown Rot Blossom Blight the disease symptoms will begin to appear in the spring shortly after blossoming. Diseased flowers wilt, turn brown and are covered with masses of spores. As the disease progresses it can spread to twigs and small branches which will begin to die back. When the branches become infected, often a sticky or gummy sap substance will be seen on the branches.
Brown Rot Blossom Blight is caused by a fungus that over-winters on the tree’s bark and will attack blossoms, leaves, branches and fruit.
To prevent and control Brown Rot Blossom Blight, remove and destroy any infected branches and be sure to properly sanitize pruning tools after each pruning cut. At the first signs of the disease spray the tree with Fruit Tree, Vegetable & Ornamental Fungicide. Repeat spraying as needed.
