GROUNDNUT :: MINOR DISEASE :: INDIAN PEANUT CLUMP DISEASE

Indian Peanut Clump Disease - Peanut Clump virus
            Earlier this disease was confused with groundnut rosstte. Now it is recognized as a distinct virus causing clump disease. The leaves turn very dark and plants become severely stunted. The disease is soil borne and transmitted by a fungus, Polymyxa graminis. The pH of the soil affects transmission. It is also transmitted by seed. The virus is rod shaped, 190-245nm long x 21nm wide, not enveloped, ssRNA genome.

Other virus diseases of minor importance occurring on groundnut are:
