Hi, I'd like help in identifying what are these tiny brown specs on dichondra leaves and how to control it. It is NOT flea beetle, which is easy to identify. It looks more like uniform spores, and is powdery when rubbed. It causes the stalks to grow taller and the leaves don't open flat. It sucks the life out of the leaves and they yellow and wither. Some leaves are infected and some not as you can see in the picture. I'd like to figure out how to control it.
Thank you!

It looks like rust. There are some pictures to compare on this page:
