Almond - Deformation

Symptoms
Chlorotic mottling and paling of leaves. Leaf tips and margins get necrotic, curl up and give the leaf a twisted, S-shaped appearance. Size reduction of leaves and nuts when deficiency is severe. Premature leaf drop.

Reasons
Manganese deficiency. Variety 'Peerless' is sensitive to Mn deficiency. The suggested range for Mn in leaf tissue is 30 - 80ppm. Generally Mn undersupply hardly occurs under field conditions.

Almond - Chlorosis

Manganese deficiency made worse by

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

Manganese is important for

  • Optimizes leaf quality to ensure good photosynthesis and supply of yield components
