Physiological Disorders:Choke Throat

  • deficiency 1
  • deficiency 2


  • It is due to low temperature affecting active growth of the plant.
  • Leaves become yellow and in severe cases, the tissue gets killed (Image1). Bunch development is normal, but when the time of flowering synchronizes with low temperature, the
  • bunch is unable to emerge from the pseudostem properly. Deficiency of Calcium and Boron also leads to similar symptoms.
  • The distal part of the inflorescence comes out and the basal part gets stuck up at the throat. Hence, it is called Choke throat (Image2).
  • Maturity of the bunch is delayed by taking 5-6 months.
