Summary
Virus diseases of tree tomato were characterized in the valleys of Pichincha province in Ecuador. PLRV, ToRSV, PVY and AMV were the most frequently identified viruses associated with viral disease symptoms in these valleys. Other viruses previously identified as CMV, TMV and TSWV were not observed in this study. Viruses PVY and ToRSV were inoculated individually to tree tomato plants through mechanical inoculations while PLRV was inoculated individually through the aphid Myzus persicae. PVY was most frequently associated with all symptoms studied and when inoculated alone caused severe symptoms. Therefore, PVY appears to be the most damaging virus of tree tomato in the Pichincha valleys. ToRSV showed slight leaf deformation and PLRV infections were also symptomatic.
