Gold fleck

• In the fruit surface around the calyx and fruit shoulder, tiny yellow spots often appear which are called gold flecks. These gold flecks appear due to deposition of calcium oxalate. With high incidence, fruits become non attractive and their shelf life also get reduced. Incidence of this disorder is increased due to

  i) Higher supply of phosphatic fertilizers
  ii) Higher supply of calcium fertilizers
  iii) Increased magnesium concentration in the fruits
  iv) Summer shading lowers the incidence of this disorder
