Data collated by K.M. Srivastava and R.K. Raizada, 1984.

Nomenclature

ICTV decimal code

56.0.1.T.D.04

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Clitoria ternatea, Crotalaria spectabilis - systemic mosaic.

Transmission

Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by seed.

Geographical distribution

Spreads in India.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show necrotic lesions, systemic mosaic or veinal necrosis.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor - necrotic local lesions.
• Crotalaria spectabilis - systemic mosaic.
• Vigna unguiculata - necrotic local lesions, systemic veinal necrosis.

Diagnostically insusceptible host species

Cucumis sativus, Arachis hypogaea, Datura stramonium, Nicotiana glutinosa.

Maintenance and propagation hosts

Vigna unguiculata.
