I would not put this as a selling point to a customer. The University does not recognize any cultivator of SA as being chinch bug resistant, they state it has improved tolerance (http://edis.ifas.ufl.edu/ep398), but that is not resistance, until then, I would not tell a customer that, because you know who they will blame when damage occurs! If they want chinch bug resistant turf - zoysia is what you should give them. Second - I think Floratam can get by pretty good during our rainy season without much additional irrigation if it has been properly feed. Still needs it during our dry periods like our last little 30 day period of no rain.
