Echinacea Virus
I'm hoping that someone can help me with a problem.
I have a weird virus that's affecting some of my echinacea in one of my flower beds. You can see what it looks like he http://www3.sympatico.ca/great/viralbynature.html Green, leathery, petals, and some are growing new flower heads out of their 'petals'. Does anyone have any idea which virus could be causing this problem? Could it have been vectored by the hoppers I found on the plants (also shown)? And my final question is almost rhetorical ... do I need to destroy the affected plants? I'd appreciate your input. Thanks. EV |

flower beds. It looks like Aster Yellows. Aster yellows is caused by a tiny organism known as a phytoplasma and is spread from plant to plant by leafhopper feeding. Once infected, there is no cure. Diseased plants should be promptly removed and discarded to reduce further spread. sed5555 |

One site mentioned that Tetracycline would cure a plant: http://www.plantpath.wisc.edu/soyhealth/caq.htm [] Remission of symptoms and even curing a plant can be achieved through the application of the antibiotic tetracycline (which is also a way to tell if you have a phytoplasma!) (McCoy and Williams 1982) I wouldn't get antibiotic for echinacea, but it might be useful for rarer specimens. I wonder how one would use it? As a foliar spray? EV |
