Bitterroot Restoration

A serious outbreak of Phoma blight (Phoma glomerata) is a new disease of mango . The symptoms of the disease are noticeable only in the old leaves. Initially the lesions are minute, irregular, yellow to light brown, scattered over the leaf lamina. Fully developed spots are characterized by dark margins and dull grey necrotic centres. Under severe infection, infected leaves get defoliated. The disease can be effectively controlled by spraying copper oxychloride (0.3%) at fortnightly intervals.
