The aim of the study was to assess the antiviral activity of selected essential oils (EOs) against Cucumber mosaic virus (CMV), both in vitro and in vivo. The observations were made using Chenopodium quinoa as a local host. The EOs were obtained from Greek oregano, thyme, and costmary. Their chemical composition was determined using GC/FID followed by GC/MS. The dominant compound in oregano EO was carvacrol (59.41%), in thyme EO—thymol (59.34%), and in costmary EO—β-thujone (90.60%). Among the analysed EOs, thyme EO exhibited the most promising effects against CMV. However, its activity was influenced by the time of application. In an in vivo experiment, thyme EO showed protective (pre-inoculation) rather than curative (post-inoculation) activity.
