Went to look at a lawn the other day. Brown spots all over. Front and back no dog on the property. When I was looking at the grass leaves I noticed a brown hour glass shaped spot about half way up. Looks like dollar spot to me. Here in WI the grass is just starting to green up. Will dollar spot last over the winter? I did some reading about it the other day and found out it is caused by a lake of N. Showed some grass I pulled to the guy at lesco he said it looked like dollar spot also. He suggested hitting it with N and see if it grows out of it. What would you do? And what has worked for you in the past?

Yes, I am licensed.

What type of grass is this infection on? What's the environment around those spots, (EX. open sunit, shaded,etc) ? Too early for dollar spot unless left over from last year. Sure it's not gray snow mold damage?

Yes it is left over from last year. The guy had a problem with it last year. Not enough fert and he would water at night when he got home from work. The grass never had a chance to dry out before it got dark.

I talked to the turf prof. at the Univesity today he said it sounds like dollar spot also. I really wasn't sure if it would last over the winter or not. He said it would. He also said to be 100% sure I could talk a sample to the turf grass center and have it looked at. I told him it was already there. I had the home owner take in a sample the other day. If the home owner takes it in it costs $20. If I take it in ( being a contractor) it costs $40 to have it looked at. I love home owners that are willing to work with you. Not to mention this house is in a neighborhood were the houses are $500,000 plus. It could be really good for business to get in to this place

That's what I was thinking. But this dollar spot issue....I some how doubt it's dollar spot. I would think it's still pretty cool up your way.

He is going to stop watering at night. He also asked about putting in a irigation system for him. That way he could set the timer for the morning. Thats a little more involved than I want to get right now. I always wanted to do an irrigation install, but not on an existing lawn. I want to try one before the lawn is put in.

I guess if the hour glass is there it must be dollarspot, I didnt relieze the disease can over winter like that, most grasses are still dormant here in central mass soil temps are still cool, I would think your area, Madison would have simalar temps,

Thats why I would just recommend fert now. and check it as spring gets warmer.

Could be dollar spot, but not active now, seeing symptons from last fall that wasn't eradicated or grew out of

I had several cases of Dollar Spot last season. Almost always from improper watering. Usually a customer that just had a sprinkler system installed. They paid good money for that thing and darn it they are going to use it. Sometimes I wonder what the irrigation installers tell the client. I had one client that was WATERING EVERY DAY! I caught her one time and said "Everytime I drive by here your sidewalk is wet. You're not watering everyday are you?" YES she says, shouldn't I be?.....Anyway, I sold her another round of N to address the problems she created!
