  • Disease is very common during monsoon season
  • Water socked lesions appear within 48-78 hours of infection
  • Later these lesions become enlarged to form light brown spots
  • Infected fruits develop soft rot.
  • Damage caused to the bark of crown roots or bark of the trunk is called as Phytophthora gummosis

Management

  • Maintain soil ph by adding lime (pH of 5.4-7.5 favours the disease).
