Welcome to the rose forum. Can you tell us where you are located and perhaps take a close up of an affected leaf? If you pull a leaf off the plant and photograph it in shade, the image might be clearer. Thanks!

Need pics of both the top and bottom sides of the leaves too.

I'm not terribly familiar with rust but this does not look like it to me. It looks more like sun burn or fertilizer burn.

I'm kinda thinking spider mites.

For what it's worth, I thought spider mites too.

Thanx all. Here are some fresh pics. I started spraying with Malathion last week for whitefly infestation of the fichus. Fichus looks better but no change on the rose.

The underside has a dusty look that can suggest mites. I am half blind and can't make out anything beyond that. Look at the underside with a magnifier. I need 5x or 6x If there is a mite problem, you will see lots of fine webbing and a few of the little crab-shaped critters, amber colored.. There will also be fine pale stippling on the upper face of the leaf. The remedy is a forceful spray of water on the underside of the leaves every day for several days.

If there are no or few mites, it is probably spray burn from the malathion.

That is not rust. If it is mites, and you have killed them, the damaged leaves will not change - they are already damaged. Any new growth should come in without this sort of damage now.

It could also be some sort of burn. Give it plenty of water, and give it a rest from any spraying or fertilizer for a couple of months and see if the new growth looks better.

Thanx all!
