It is difficult to tell from the picture. Does it look like there is webbing?

White foam like that usually makes me think of spittlebugs, which can usually be controlled with a good blast of water. On the other hand, black leaves on rudbeckia make me think of fungus.

looks like a milky-spore type fungus .. try googling milky and see what you end up with ... Other than that, try a local botanist place ... or arboretum .. they might know. Good luck.

It also looks like a fungus to me. Once you get rid of it (as per some professional advice), you may want to thin the clump a bit by cutting out every third stem. That way there is better aeration through the plant which will deter this from happening again. I do this with my phlox and it helps keep down the mildew which usually grows on them.

I had this happen to mine last year. One day they were fine the next they looked all black and mill dewy. I cut them off as I didn't want them to infect my other plants. This spring they are coming back up and the leaves look healthy so we will see.

If it looks like soap suds it's probably spittlebugs. Does it look like this? http://en.wikipedia.org/wiki/File:Spittlebug4383.JPG Spittlebug (Froghopper) larvae make this foamy stuff. Just hose them off. The black on the leaves is a whole different matter & pics of it are needed.

I agree with Douglas and Judy the foamy stuff is spittle bugs. Just give a good drink of water to the plants and the spittle will be gone. Black stuff sounds like black sooty mold but a picture is worth a thousand words in describing it. I have a lot of black eyed susans, live in the the northwest and have never seen the black on the leaves so I am intrigued. Keep us posted with a picture.

I planted 16 Black-Eyed Susans last year. They never came up.

If it looks like someone spit on your plant its Spittlebug. Spray them off with a squirt from your hose. :)

thanks again for all the help, i found a site on the net that recommended spray with a milk solution, since the back on the leaves is a fungus, and the milk is a fungicide. it sure is nice having so many helping
