Followup to my problem (hope this helps others).

I took a few affected blades of grass to my local garden center, they
immediately identified it as a fungus. Per their recomendation, I
applied "Hi-Yield Fungicide granunes with Balyeton". The bag says it
covers 3,000 sqft, but I used the curative application... only
covering 1,500 sqft. I applied it 6 days ago and I can already see an
improvement. Some areas may need additional treatment, but that's
exactly what the garden center said. His specific instructions:

Water for 5 minutes before applying. Then apply the fungicide. At
least 24hrs later, water normal application. You might need to
re-apply certain areas. When you start to see a few blades of grass
start to poke through, fertilize the area.

In 6 days, I can tell that ~some~ areas are starting to grow back and
I'm only watering twice/week (high temps in the high 80's, low 90's).
The worst areas aren't coming back yet, but they aren't getting worse.
I also haven't seen any new areas of fungus activity.

Hope this helps others!

hi.

my lawn looks exactly the same. in the dry yellow dead patches i put some
soil down since it was lower than the rest of the lawn. i also planted some
seed. i always hear people mention chinc bugs and grubs. let me know if
you determine your bug? i live in southern ontario. would it be posible to
look for bugs now?

someone told me to cut out both ends of a can and place on grass where the
dead meets the living grass. fill with water and wait 10-15 minutes and any
bugs will float to the surface.

i am going to put some weed n' feed down soon. Question: when should i use
insecticide? before, after or at the same time as i weed and feed?
