I do have to worry about it. The spores are in the soil in my neighborhood. So even if I grow it from seed they are likely to succumb

The spores are also airborne, so any plant anywhere can be infected.

Thats good to know - I guess I have just been lucky.

I started mine from seed, and they were infected later.

So far, so good. No signs of disease and flower buds are forming.

Mine were started from seed but developed the disease long after being planted on ground. No signs yet in balsimina yet. I get hundreds of volunteers every year. By late summer they develop something that looks like powdery mildew and then I yank them.

Hi all,

Back in February, Anne mentioned watering with a systemic fungicide as a preventative or possible cure, and I think that would be worth a try. There are several good systemic fungicides. I have found that Tebuconazole is effective in preventing Powdery Mildew in my indoor zinnias.
