Deficiency Symptoms

Deficiency symptoms appear in the form of interveinal chlorotic mottling of apical part of the second set of leaves.  The entire laminae become severely mottled and the interveinal chlorotic areas develop light brown irregular necrotic patches.  These patches, which are initially more conspicuous near the leaf apices, later spread to the entire laminae, which eventually turn severely necrotic.  Symptoms gradually spread from the middle to the young and old leaves.
