I hear ya! They'd be gasping at my yard! (Or maybe not. I am sure they have seen much worse.) But my yard is not a pristine and pest free yard. And I do get various types of rust on different plants in my yard. It's Florida! Humidity and mild winters breed rust here just like bugs. If I was a scientist (biology), living in Florida, this would probably be a dream place to live!
