[R]Identification
Techniques to detect the virus include the following: classical assays with infected host indicator plants, serological tests, examinations by spectro-photometry and observations using the electron microscope.

[R]Description
The plants have a rickety appearance. The leaves blister and deform.
The lamina of the leaf is covered with large irregular spots that are pale green to whitish in colour, resembling a mozaic.
The youngest leaves appear wrinkled, blistered, asymetrical, and are often reduced to a single principal vein with small pieces of tissue on each side.
The most severely affected plants rarely produce fruit and die prematurely. Their capitula are malformed, being smaller in size and are altered both in form and colour at the bract level.

[R]Biology
.

[R]Epidemiology
The pathological manifestations of the disease appear in autumn and are most intense during winter.
The virus can survive in the soil and remains infectious for a long time.
The vector is unknown. No other natural host plant is known.

[R]Treatement
In addition to the measures suggested for the ALV (see Artichoke latent virus), fumigation of the soil is also practiced.
