Melons - Chlorosis

Symptoms
Recently mature leaves show interveinal chlorotic mottling. On closer examination one may detect pale, watery patches with a fine brown border, especially towards the leaf margins. With severe manganese deficiency, brown necroticspots may be shown on the leaf surface. Numerous purplish-brown spots may appear on the leaf stalk or stem.

Reasons
Manganese deficiency. While rarely seen, transient deficiencies can occur in sandy or peaty soils of a high pH, and can be overcome by using micronutrient sprays (manganese is not very mobile in the plant).

Manganese deficiency made worse by

  • Organic soils
  • Sandy soils
  • High pH
  • Cold wet periods
  • Fluffy soils

Manganese is important for

  • Chlorophyll formation and oxide-reduction in cells
  • Protein synthesis and metabolism
