re: Paging Grass Gurus - What’s going on with my St. Aug?

I am having a similar issue with the St. Aug in my back yard. I initially thought it was fungus so I treated with a granular application. Although I saw some improvement, it wasnt much. I then noticed the chewed blades so I sprayed with Talstar 2 days ago. I noticed a ton of moths during that application, so I think I have a combination of a fungus and sodworms.

My question is, how often can I apply the Talstar and the fungicide? Should I do anything to help the grass grow in the places that had the damage?

Thanks for the help in advance!
