A fungal infection with Fusarium in Vandas can be lethal if it remains untreated. I’ll sum up everything I know about this infection and show pictures (including follow ups) of three cases. All information in this video is based on my oberservation, experiences and internet research - it's just my hobbyist's point of view. Fusarium infections in orchids is a complex topic. I'm a hobbyist who is not able to perform tests to verify a diagnosis, thus my perspective is limited. Yet it appears to me that anthocyanin deposits (a purple ring) in rhizomes can occur in healthy plants. A possible explanation: Anthocyanin deposits might act as a defense mechanism in parts of the plant that are exposed to pathogens, for example in rhizomes or roots in bad medium. That might be the reason why purple rings are found in plants that suffer from some kind of infection, let it be Fusarium or something else. And if we find a purple ring and the plant appears healthy, the defense might have worked. These are not hard facts, though, please do as much of your own research as you can. It's just a different perspective that I wanted to share. Happy growing! :)
