I have rust on plumeria, cannas, and my fig tree as well as some of my daylilies. Hey, it's Florida. We have every fungus known to man here.
Recently read a review (sorry I have to find it again) by UF researchers on a new fungicide called Actinovate. The package says it is rated for edibles, and for organic use under the guidelines of the USDA's National Organics Program. I'm trying it on all my rusty plants, as well as on my orchids to prevent their diseases.
