Virus confirmed by EM
My hippi patch, which tested negative for several viruses by ELISA, does have a virus after all, as confirmed by electron microscopy at the University of Minnesota Plant Disease Clinic. I don't know what type, just "numerous filamentous virus particles". I sent a bulb with a leaf, and the leaf pictured below. I don't know which portion was actually tested. I may know more when I get the official report. My nearby mottled alpine strawberries were virus free. The hippi patch and any others I see in my yard with mottling will soon be dug up and thrown in the trash, and the shovel sanitized.
