Tomato chlorosis virus (ToCV) and Tomato infectious chlorosis virus (TICV)

Learn about the symptoms, spread and distribution of these economically-damaging viruses, and how to control outbreaks when they occur.

What are the viruses?

Tomato chlorosis virus (ToCV) and Tomato infectious chlorosis virus (TICV) are whitefly-transmitted criniviruses. 

Both viruses can have serious, yield-reducing effects upon tomato production if suitable control is not administered.

Recent outbreaks in other countries have caused extensive economic damage to the production of tomatoes.

Although both viruses are considered to have only tomato as their major economic host, they can infect a broader range of plant species, including a range of common weeds.
