Copper
Deficiency Symptoms :
Deficiency symptoms appear as interveional chlorosis of the upper half of the old leaves starting from the tip of the leaf. Chlorosis is generally restricted to the apical half of the lamina. Chlorotic areas later develop dark brown necrotic scorching, which spreads along the margins towards the base of the leaf. Laminae becomes shriveled and withered. Marginal scorching of the leaves becomes more pronounced and brown necrotic spots develop near the midrib.
