Aster Yellows Resistant Plant? #879090

Hello. I have a quick question regarding aster yellows. I just lost three echinacea purpurea plants to aster yellows in one of my gardens. I dug them out and I know I can replant the area, but need to make sure that it's with a plant that's not susceptible to aster yellows. I was thinking of putting in lobelia siphilitica to replace the purple coneflower. Is this an option? I haven't found it obvious on-line when researching this topic. I've seen that there are "over 300 species" susceptible to aster yellows, but in general, it's very vague. Thanks so much for your assistance. I'm hoping to avoid loosing more plants to that disease. If you have other suggestions regarding this topic, I'd love to hear them.

There is a mite that can look like aster yellows.

Plants resistant to aster yellows have not been identified, there are a few that show less susceptibility:
plants that are not as susceptible to aster yellows. Verbena, salvia, nicotiana, geranium, cockscomb and impatiens are among the least susceptible plants.
You might try a row cover that excludes insects when the leaf hoppers are active. Please take a look at the mite if only coneflowers were affected because aster yellows has a broad host range and if present can infect many species.
