Vegetative propagation
Chrysopogon Plumulosus Hochst. can be propagated vegetatively through stem cuttings. The cuttings must be taken during the active growing season and treated with rooting hormone to improve success rates. However, vegetative propagation is usually limited to experimental purposes.
Disease Management
Chrysopogon plumulosus is commonly grown in arid and semi-arid regions. The plant is generally resistant to diseases, but it can be afflicted by a few fungal diseases like leaf spots and rusts.
To manage these diseases, one can use fungicides in accordance with the manufacturer's instructions. It is also important to remove and destroy the infected parts of the plant. Proper sanitation practices like removing the weed hosts and maintaining proper drainage can also help keep the plant healthy.
