Date :Définition
Virus disease of tobacco in the USA, so far unkown in Europe. It is transmitted by lice; the disease causes leaves to become deformed. The only resistant type is nicotiana tomentosiformis.
Note :
It is first seen in spots on the tip leaves, later in mottling of the leaves lower down. It differs from mosaic in that the tip leaves are not mottled. It is spread by aphids and present in most tobacco areas.
