Hi Alligator and
I live in Florida also, but since I spray I am not a good person to say what is resistant or not. There are several people on here who will answer this once they see this though.
The only one I can say for sure is more resistant here, that I know of, is ROLLING RAVEN. There are 6 really HUGE clumps that are extremely clumped up together; it's hard to get really good coverage when I spray and they hardly ever have more than a few specks anywhere if at all. The only reason I pay attention to these is because I always worried about not spraying them well and would check them often.
