I see Spurge Power works as a post-emergent treatment but understand it will injure St Augustine grass. I also see other products but would like your recommendation. I’m in northeast Florida and temps are in the upper 89s to low 90s right now. Thank you.
Spurge Power is labeled to be used on St. Augustine grass. Per the product label, they do not recommend broadcasting this product when air temperatures are over 80 degrees F. They recommend only spot treating when temperatures are over 80 degrees F. If temperatures exceed the recommended temperature range, do not apply.
