Urban Farm DB summary
A survey of pests and diseases in crops associated with hydroponic systems, organopónicos, and urban gardens in Mexico identified three viral symptomatologies in lettuce (Lactuca sativa), celery (Apium graveolens), and Castilla melon (Cucumis melo), linked to aphid vectors. Using indicator plants, optical and electron microscopy, and ELISA (DAS and indirect variants), the causal agents were identified: Lettuce Mosaic Virus (LMV) in lettuce and a race of Cucumber Mosaic Virus (CMV) in celery, both first reports for the country, and Papaya Ringspot Virus race W (PRSV) in melon, never previously found in that crop. An aphid species colonizing lettuce was also identified for the first time as an LMV vector.
