Identification Symptoms

  • First symptoms start with the onset of monsoon. Appearance of light yellow foliage with loss of turgidity and epinasty.
  • Plants, a later stage, show unthriftyness. Subsequently, premature shedding and defoliation.
  • Some of the twigs become bare and fail to bring forth new leaves or flowers and eventually dry up. Fruits of all the affected branches remain underdeveloped, hard and stony. Later, the entire plant is defoliated and eventually dies.
  • The roots also show rotting at the basal region and the bark is easily detachable from the cortex. Light brown discoloration is also noticed in vascular tissues.
  • The pathogen attacks young as well as old fruit bearing trees but older trees are more prone to the disease.
