Abstract
Orthotospoviruses and tobamoviruses continue to be important pathogens of ornamental and vegetable crops.
The emergence of tomato chlorotic spot virus (TCSV) in Florida and the Caribbean region since 2012 has complicated the Orthotospovirus situation in this part of the world, where tomato spotted wilt virus (TSWV) had previously been the only significant Orthotospovirus. In 2016, TCSV was first identified in sweet basil (Ocimum basilicum), Madagascar jasmine (Marsdenia floribunda) and purslane (Portulaca oleracea) in Florida.
In 2017, TCSV was first identified in ornamental portulaca in Florida.
TSWV has not disappeared and in 2018 was identified for the first time in society garlic (Tulbaghia violacea) in Florida.
Subsequently, additional orthotospoviruses have been identified in multiple ornamental crops in the US. Several tobamoviruses have also been detected in ornamental plants.
Hoya chlorotic spot virus continues to be detected in Hoya spp. along with a second Tobamovirus. Brugmansia latent virus has been discovered in solanaceous ornamentals.
Frangipani mosaic virus was detected for the first time in Plumeria spp. in Florida in 2019. Detector dogs show promise for plant viruses offering opportunities for rapid diagnosis to enable real-time management decisions.
Due to continuing movement of viruses and plants, tracking emerging viruses infecting ornamentals in Florida and beyond will enhance our ability to manage these viruses.
