Ahhhh, summer

This photo is of some type of chemical injury to 4 white green.  The definite borders to this type of injury immediately indicate some type of spill or other application.  This spot does not smell of gas or oil, and grass is coming back in the centers which tell us that whatever was here provided only temporary toxicity.  My guess would be single malt scotch or some other adult beverage.
Cheers,
