Yellow mold on oxalis- what it it? (Photo)

[Fordian]

Any idea what this is and how to treat it?

It's an orangey/yellow dust on the underside of my oxalis plant!

Thanks.

Cut off leaves

It’s Oxalis rust. Quite common and often seen on Oxalis weeds growing in the garden. Fungicide might help, but I think it loses its leaves in winter and goes dormant.

Thanks!
