• The entire lamina become severely mottled and the interveinal chlorotic areas develop light brown irregular necrotic patches.
• These patches, which are initially more conspicuous near the leaf tips, later spread to the entire lamina, which eventually turn severely necrotic.
• Symptoms gradually spread from the middle to the young and old leaves.
