Sanitation is also one of the practices to control viroid diseases.

Biological indexing involves comparing the molecular component of a viroid infecting various indicator hosts.

Coconut cadang-cadang viroid (CCCVd) had been reported infecting oil palms in Malaysia.

Chemical control on the insect population can eradicate the infection by plant viroids.

Reservoir hosts are the plants that are showing mild symptoms upon viroid infection.

Excluding the natural hosts from the potential host plants in the same planting site is the most effective control means.

Latent infections of viroid are common among ornamental plants.

Both plant viruses and viroids can manipulate organelles of the plant cell.

Plant hosts that are infected via pollen transmission of viroids potentially produce infected seed.
