Begomoviruses are part of the group of emerging viruses that affect crops of agricultural interest worldwide. Weeds can easily become alternate hosts of these viruses and be a source of inoculum for them. The objective of this work was to detect bipartite begomoviruses present in weeds collected in tomato crop in Cundinamarca, Colombia. Weeds were collected with and without viral symptoms in tomato crops located in the municipalities of Pasca and Fusagasugá, Cundinamarca. The total genomic DNA of each weed was purified and to demonstrate the presence of begomovirus a polymerase chain reaction was performed with specific oligos for detected the genomic component A viral. 36 weeds were collected, of which 22 species were identified taxonomically. Stellaria media (L.) Vill., Veronica persica Poir., Galinsoga ciliate (Raf.) S.F. Blake, Malva sylvestris L. and one species of the family Asteraceae were positive for bipartite begomoviruses. For the species Stellaria media (L.) Vill. and Galinsoga ciliate (Raf.) S.F. Blake, they constitute the first report worldwide as begomovirus hosts. The species Veronica persica Poir. is identified as a reservoir of begomovirus for the first time in Latin America. Finally, the species Malva sylvestris L. and a species of the family Asteraceae are reported for the first time as hosts of begomoviruses for Colombia. Effective control of weeds identified as hosts for begomoviruses is an effective strategy to reduce the impact of this virus family on tomato crops.
