Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Passiflora edulis, P. suberosa, P. subpeltata, P. aurantia, P. foetida, Arachis hypogaea, Centrosema pubescens, Glycine max, Macroptilium atropurpureum, Phaseolus vulgaris - necrotic and chlorotic local lesions or streaks, mottling, rugosity.

Transmission

Transmitted by a vector; an insect; Aphis gossypii, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in the South and Central American region; Australia and Brazil. Found, but with no evidence of spread, in New Zealand.

Experimental host range

Many (>9) families susceptible.

Diagnostically susceptible host species and symptoms

• Macrotyloma uniflorum - large reddish-brown local lesions; systemic necrotic spots, vein necrosis in upper leaves, stem and petiole necrosis, premature death.
• Macroptilium lathyroides - necrotic or chlorotic local lesions; systemic vein necrosis in upper leaves, leaf fall, bud blight.
• Phaseolus vulgaris cv. Bountiful - necrotic or chlorotic local lesions, then systemic mosaic and necrosis along veins.
• Passiflora edulis, P. suberosa - systemic vein clearing, rugosity, mottle.

Maintenance and propagation hosts
