Dieback disease hits neem trees in Telangana again.


About Dieback Disease

  • The dieback disease was first reported in the country during the 1990s near Dehradun in Uttarakhand, while it was first noticed in Telangana in 2019.
  • The dieback disease is mainly caused by the fungi Phomopsis azadirachtae.
  • The dieback disease affects leaves, twigs and the inflorescence of neem trees of all ages and it causes almost 100% loss of fruit production in severely infected trees.
  • The dieback is a fungal disease but the neem trees are sometimes hit by insect infestation and the combination of both increases its impact.
  • The disease posing a threat to the neem trees has been identified as twig blight and dieback disease in Telangana, and it has reappeared in the state this year on a massive scale.
  • The appearance of symptoms starts with the onset of the rainy season and becomes progressively severe in the later part of the rainy season and early winter.
