Large Areas of Zoysia Ultimate Dying
I had my entire yard sodded with Zoysia Ultimate in October 2010. It never seemed to establish well in some areas. Now it is September 2011 and it seems like the whole yard is dying. It has rained about 8 inches in August. The soil is sandy and well irrigated. I suspect fungus. I live in a restricted deed neighborhood and am afraid the HOA will get on me; plus I am broke. :-) Help.

Yes, it may be a fungus. And with lots of rain, this will aggravate the fungus problem. A cheap thing to try is to apply baking soda to the lawn. Use 1 TBLS baking soda, 1 TBLS vegetable oil, 1 TSP Murphy's Oil and 1 gallon of Water. Mix all this up and that will give you about 1 gallon of a homemade fungicide that you can spray on the lawn to help combat the fungus.
Thanks Heather, I tried Bayer, then Scott Lawn Fungus control about 3 weeks apart, but can't tell if that made any difference yet. I will try your recommendation next. I had been mulching the grass since it was installed last year. Should I be bagging it instead? Could I also have a thatch problem that is aggravating the situation? Could I also have a pH problem after all of the rain?
