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).
