Tobacco mild green mosaic virus has been reported on a range of hosts in: Australia, France (including Corsica), Germany, Iran, Israel, Italy, Korea, Madeira, Panama, Taiwan, Tunisia, USA, Venezuela. Not all hosts are known to be infected in these countries.

The most likely pathway of entry for this virus is on ornamental plants for planting from countries where the virus is known to occur. Ornamental plants are known to be symptomatic albeit the stage at which young plants exhibit symptoms is unknown. 

The virus is very likely to establish under protection and moderately likely outside, if no control measures are taken. 

Economic impact is likely to be ‘medium’ but with a degree of uncertainty. Further investigations need to be carried out into the varieties of tomatoes that can be infected and the effect of TMGMV on Capsicum and tomato fruit quality and yield. Ornamental hosts are symptomatic and so the effect of the virus on plant quality will have negative economic impact. 

The endangered area is Capsicum, tomato and ornamental hosts, especially protected crops but also plants grown outdoors in the summer.
