Raspberries - Chlorosis

Symptoms
Severely decreased growth with small leaves. Reduced or no fruit set. Older leaves show symptoms of senescence with chlorosis and subsequent necrosis. In the beginning leaf veins remain green but finally the leaf tissue is completely pale. Necrosis proceeds from the margins and interveinal areas. Premature leaf fall.

Reasons
Nitrogen deficiency (right) Leaves should contain 2.4-4.0% N.

Nitrogen deficiency made worse by

  • Low or high pH soils
  • Sandy or light soils (leaching
  • ) Low organic matter
  • Drought conditions
  • High rainfall (leaching) or heavy irrigation
  • Addition or high levels of non-decomposed organic matter/manure (eg straw)
  • Fast growing crops

Nitrogen is important for

  • Improved crop vigor and development
  • Increased fruit set, yield and quality
