Detection and control measures

Because of its extreme variability, it is not easy to identify this virus in the laboratory.

There are several strains and variants found in one or other of the crops infected. The potato may be infected by isolates of the two serotypes (A and D). The Elisa test should use antibodies that recognise both serotypes.

Biological diagnosis is also possible in the greenhouse by inoculating tobacco plants or chenopods.

No method of control has been recommended for this virus, apart from crop rotation and thorough weed control.
