This only appeared since we've had a couple days rain. It's on my sunflowers, some salvia and my prairie coneflowers.

It appeared to be pretty locolized around the bird bath, but I found another sunflower over by the arbor that seems to have the start of this.

Already I cut the limbs off the salvia and coneflower and I yanked up every bit of sunflower that seems infested and all went into the fire pit.

What do you think?
