fungus damaging lawn quick, need help

Hi, I have 2 month old sod which is getting destroyed by some kind of patch fungus, I sprayed immunox (myclobutanil) every 7 days and I am not really sure if it is doing anything, it starts with little circles turning brown. Also the problem area when viewed from a distance can appear to have a blue/purple hue to the grass that are around it.

The local nursery say it could be grubs but I can pull out those dead grass it still has some roots. I tend to think it is fungus because it is only areas with afternoon shade by the house that is prone to this. I have started to deep water 1 hour 2 times a week and letting the grass dry out fairly well.

Would Bayer advanced lawn disease control (triadimefon) granules work better? I need to do something as the new sod isn't established enough to deal with this well. The spots are appearing very quickly.

Thanks in advance
