No

CLVd00-2

Pepper was reported as a symptomless host only when inoculated under experimental conditions. No references found indicating pepper as a host of Columnea latent viroid under natural conditions. Tomato is a known host.

Though not confirmed as a host, commercial testing is available using the NAKT NL protocol

CLVd00-2

Pathway not proven. There is conflicting information on whether seed is a pathway for Columnea latent viroid in tomato. One reference indicates Columnea latent viroid could be detected on the seed, however, another indicates transmission did not occur. A recent reference indicates seed transmission occurred in 3 out of 4 varieties of tomato inoculated and grown under experimental conditions. Columnea latent viroid infection in tomato is considered self limiting in that extremely small numbers of seed are produced in infected tomato plants.

Yes

Commercial testing available using the Naktuinbouw reference protocol.

No references found indicating a seed treatment is effective against Columnea latent viroid in tomato. Seed treatments to sanitize the seeds against Columnea latent viroid are considered to be of little use in preventing seed-borne transmission, ISF
