Fig mosaic virus is a segmented, negative sense, single stranded RNA virus from the genus Emaravirus and family Bunyaviradae. It was first described in 1933 as the causal agent of fig mosaic disease, which causes mosaic spots on leaves and fruits, reduced yield, and defoliation. The disease is transmitted by the eriophyid mite vector and has been observed in several countries. Management strategies include using resistant varieties, controlling mites with horticultural oils, and never planting infected material.

3. History
 Fig mosaic disease was first described and
suspected to be of viral origin in 1933 by Condit and
Horne.
 This disease and associated virus has been
observed in Italy, Australia, Spain, turkey ,Syria and
united states.

4. Casual Agent
Casual Agent :
casual organism of fig mosaic is fig mosaic
virus.
Vector :
Eriophyid mite

5. Symptoms
– Infected trees seem to produce smaller and fewer fruit.
– On leaves, mosaic spots are distinctly yellow.
– The margins of the yellow spots blend gradually from a light yellow color
into the dark green.
– Mosaic spots or lesions may be uniformly scattered over the surface of
the leaves.
– Mosaic spots on fruits are very similar to those on leaves, but less
conspicuous.
– Due to this disease decrease fruit yield and defoliation occur.

8. Management
– Use Resistance variety of fig tree.
– Control the fig mites
– No chemical control shown to effective in treatment of this disease.
– Horticultural oil(crop oil, citrus oil) is used to control the infiltration of
mites.
– Examine the plant before planting in the field.
– Never use infected plant material.
