lesions seem too big to be leaf spot...

Hmmm , not sure if I would bite the brown patch, I'de still say Dollar Spot..

Fertilizing history would help...

When was the last 3 treatments of fertilizer?

What fertilizer was used each time?

What form was the N in? Urea, Ammonium 'something', or 'something' Nitrate?

Was it time release fertilizer? Poly coated? Sulfur Coated? What percent was time release?

What rate was it applied each time?



Either way, have your lawn aerated. Check the thatch and if it is over 1/2" de-thatch it (be careful not to harm the active growing turf).

If you aren't, water in the morning, not evening. Figure how long it takes for the first inch of soil to dry out, then water. Water long enough so that 3 hours after watering you can dig down and the soil is moist 6" down. Then do not water more then that.

Bag the clippings until the disease is gone.

For treatment- You can try 123 NPP, it basically causes an enzyme that hydrolyzes (melts) fungi. Get it here... ICTorganics.com

Get the fert info and we might be able to diagnose it a little better...

Dollar Spot for sure, Get yourself a good Fungicide. We use a Lesco Product called Manicure.

Manicure is not labeled for residential lawns. If you are going to suggest a fungicide for residential, you may consider Trinity or Armada...
