Banana - Chlorosis
Symptoms
Iron deficiency causes the banana leaves to become yellowish-green and later totally yellow. Interveinal chlorosis starts from the bottom and the margin of the leaves and progresses to the leaf tips giving the leaves a mottled appearance.
The midrib and the leaf veins remain green for a longer time, but also fade with severe deficiency.
Symptoms start on the younger leaves.
Reasons
Iron deficiency
Nitrogen deficiency also leads to yellowing of the leaves, but symptoms start on older leaves and the leaf veins or the midrib do not remain green longer.
Sulphur deficiency also causes yellow leaves starting on younger leaves, but the whole leaf and the veins or the midrib become evenly green.

Iron deficiency made worse by
- High pH
- Water logged soils
- Calcareous soils
- High copper, manganese or zinc soils
Iron is important for
- Chlorophyll and plant enzyme formation, respiration processes
- Improved plant growth and yield
- Boosts bunch weight and hands/bunch
- Increases TSS content of fruit
