Tuberose (Poliantha tuberosa)

Thrips

Symptoms

  • Thrips feed on leaves, flower stalk and flowers.
  • These suck the sap and damage the whole plant.
  • Sometimes, these are associated with a contagious disease known as 'bunchy top', where the inflorescence is malformed.

Management

  • Give sufficient irrigation as plants lacking irrigation are most susceptible.
  • Hang blue sticky traps to attack and catch insect.
  • Place plastic or paper mulch in the soil to suppress the emergence of pupae from the soil.
  • Spray neem garlic emulsion (20 ml neem oil + 20 gram garlic paste + 5 gram bar soap/litre of water).
