Magnesium deficiency-Potatoes

Συμπτώματα
Symptoms begin with yellowing in intercostal areas at the base of leaflets or leaf margin. The chlorosis expands to the whole leaf as the deficiency continues. The margin often remains green. Eventually necrotic patches appear in the yellow areas which terminate as intercostal leaf scorch. Symptoms are most severe in the oldest leaves, which have green veins and large areas of marginal and intercostal necrosis.

Αιτίες
Severe magnesium deficiency. Manganese deficiency is similar but here intercostal yellowing starts on younger leaves and the necrosis is usually in spots along the line of the veins.
