Raspberries - Chlorosis

Symptoms
Older leaves show interveinal chlorosis, sometimes followed by a faint necrosis. Marginal scorch spreads allover the leaf blade. Total growth is only moderately stunted. Very poor flowering and fruiting.

Reasons
Copper deficiency Levels of 2-50 ppm Cu in leaf tissue are recommened. Cu mobility and uptake may be restricted by high soil pH and excessive P, Zn, and Al. Furthermore, Cu adsorption to Fe, Al and Mn oxides can be significant.

Copper deficiency made worse by

  • Organic soils
  • Chalky soils
  • Sandy soils
  • Reclaimed heathland
  • High nitrogen applications

Copper is important for

  • Component of enzymes
  • Important role in photosythesis and phenol metabolism of plants
  • Regulation of destructive superoxide radicals inside cells
  • Prevention of fungal diseases
