Disease, dry, and the other

As if it wasn't hard enough to manage fine turf this year.  We have seen it all and then some.  There are several patches of grass that appear to be stressed, and die back from a small circle, upon closer examination we found that buried in the turf is a small ball like the one in the photo.  My best guess is that these little guys fell from the sky during fireworks celebrations.  I don't know what it is, except it is metallic purple, and grass doesn't like it.  If you see such a small object feel free to take it home with you, compliments of me, I have a large enough collection in my cart now.
Tired and cranky,
Turf
