Cork Spot

Symptoms

  • The initial symptoms of this physiological disorder appear as small blushed area on the skin of the fruit above the affected brown spot.
  • The affected tissue is usually much harder than the healthy tissue.
  • Boron and calcium deficiencies are occasionally found responsible for development of cork spot.

Control

  • Proper nutrient management especially boron and calcium helps in preventing this disorder.
