I noticed that some of the leaves on my pudicas were yellowing and a lot had dropped off. On closer inspection they had rust underneath the leaves. I ended picking off a lot by hand. I've never seen rust on these plants before - the plumeria, yes. So, this was a surprise. Otherwise they look healthy - no blooms yet; but they've been fed and pampered a bit.

Plumeria pudica is the last one that should be getting rust.

I see a few leaves with rust too, it's going to get worst when it rains because the wind can spread the rust spores faster.

Wasn't expecting this. I've plucked off a few that looked bad. Tomorrow I will spray a fungicide with copper and hope that helps.

I had rust on my plumeria last year, but never on the Pudica. I sprayed the leaves today -- I'll keep checking, Hope I don't have to repeat the spraying -- it does drift and they're right in my flower beds. I don't want to cause problems for the butterflies and bees, and I have a lot of bees flying around. They have set up a home in an upside down clay pot which has a bird bath on top; there must be enough of a gap for them to get into the big pot (which has a large drainage hole).

When I had only a few plumerias, I used to cut the affected leaves and then bag them. Now' I just have too many to worry about them. I doesn't seem to affect the qualities of the bloom.
