Phoma blight of mango
|
Phoma glomerate (Corded) Woolly and Hochapf. The symptoms appear on old leaves only. Initially the lesions are minute, irregular, and yellow to light brown and scattered over the leaf surface. As the lesions enlarge their colour changes from brown to cinnamon. Fully developed spots are characterized by dark margins and dull grey necrotic centers. In severe cases withering and defoliation of infected twigs occur. Spraying with benomyl 0.2 % followed by COC 0.3% was found effective.  |
