TCDVd
TCDVd is closely related to the Potato spindle tuber viroid and shows uncertain seed transmission in tomatoes. Some studies detect the viroid on seeds, but grow-out tests find no clear spread. The viroid primarily spreads through plant-to-plant contact, grafting, and contaminated tools. While no insect vectors are confirmed, mechanical transmission via chewing insects or bumblebees may occur. Risk assessments conclude that seed transmission and field establishment are unlikely.
