Nomenclature

ICTV decimal code

57.0.1.T.D.11

Host range and symptoms

Natural host range and symptoms

Symptoms Arachis hypogaea (wild hybrid) - few chlorotic rings, green blotching, smaller leaf laminae.

Transmission

Virus transmitted by mechanical inoculation.

Geographical distribution

Found, but with no evidence of spread, in Oklahoma, U.S.A.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Arachis hypogaea cvs Pronto and Tamnut 74 - severe leaf chlorosis and distortion, plants stunted.
• Glycine max - systemic leaf chlorosis (some cultivars).
• Phaseolus vulgaris cv. Top Crop, Chenopodium amaranticolor - local necrotic lesions.

Diagnostically insusceptible host species

Cucumis sativus, Datura stramonium, Petunia × hybrida and Vigna unguiculata.

Maintenance and propagation hosts
