They do not kill plants, so they are just a product of proper environment for them. They are more likely to grow when plants are sick to begin with, though.

In order to get rid of them for good, it will be necessary to find out the underlying disease. I would guess that some bacteria or algae is around the area, which if widespread enough, will require the inspection of your local extension service.
