ICTV decimal code

74.0.2.T.016

Host range and symptoms

Natural host range and symptoms

Symptoms usually none. Symptoms sometimes line patterns.
• Sambucus canadensis - symptomless.
• Pelargonium × hortorum - occasional line patterns.

Transmission

Vectorless soil transmission. Not transmitted by Macrosiphum euphorbiae, Myzus persicae. Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Geographical distribution

Found, but with no evidence of spread, in the U.K. and in Europe, Canada and the U.S.A.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show symptomless or chlorotic local lesions.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor, C. quinoa - chlorotic local lesions, sometimes systemic spots.
• Cucumis sativus, Nicotiana clevelandii, N. tabacum cv. Xanthi, Petunia × hybrida - symptomless.

Diagnostically insusceptible host species

Brassica campestris ssp. pekinensis, Phaseolus vulgaris, Pisum sativum.

Maintenance and propagation hosts
