Warm season Grass Fungus.... help!

Hello everyone I just noticed this fungus today on my Meyers Zoysia Grass. I applied a second application of Scott's disease EX control a few weeks ago for yellow patch and it cleared it up and now I'm getting these two problems. Can I get some help here on how to cure these issues! I spent way to much time and money to let my yard turn to crap. Please help! Currently it's only on a few spots.. but if this is happening more must be coming!
