Tospovirus is one of the most important genera of viruses, causing economic damage to more than 800 susceptible plant species.  Tospoviruses have a very wide host range and can be transmitted by ten different thrips species.  Using disease-free and disease-resistant tomato transplants is the best way to prevent the spread of tospoviruses.
