Tridge summary

The chili pepper mild mottle virus (CPMMoV), originally from Asia, is causing concern in Spain's pepper crops, with outbreaks identified in Granada and the Basque Country. Initially misidentified as other viruses, it was later confirmed by NEIKER, IBMCP, and IAM-UPV in 2022. The virus specifically affects pepper plants and not tomatoes, with transmission possible through contaminated seeds at a rate of 0.9% to 8.5%. It has also been detected in ornamental nightshades in the United States, raising concerns for the risk to other horticultural and ornamental crops. Researchers recommend comprehensive studies, including seed analysis, to prevent the spread of CPMMoV, as Europe continues to grapple with new viruses in its agricultural areas.

The appearance of the chili pepper mild mottle virus (CPMMoV) is causing concern in pepper crops in Spain. This pathogen, originally from Asia, has been detected in Granada and the Basque Country. In 2019, during a field study in pepper crops in Bizkaia and Granada, symptoms similar to those caused by tobamovirus were observed, but the serological tests were negative. for the main pepper viruses. Only DASS-ELISA analyzes to BPeMV (pepper mottle virus) were positive. In 2022, it was confirmed to be CPMMoV, first identified in Peru in 2021. The identification was carried out by NEIKER, the Bizkaia Plant Protection Center, IBMCP and IAM-UPV. Currently, CPMMoV appears to be established in Bizkaia, although not in Granada. Researchers believe that its introduction is due to the importation of contaminated seeds from Asia. This virus affects pepper, but not tomato, and can be confused with other tobamoviruses.
