What's wrong with this baseball field turf?

[aeration]

Went to a minor league baseball game last night. The turf didn't look good. It looked ok from behind homeplate (where I was sitting) but from the outfield, the problem was easily visible. Any ideas?

Dollar spot!

Yup! It's very humid inyour area. Their are a few products that can treat this.

The most common fungicides used are: benomyl, anilazine, and thiophanate.

Make two applications of a contact fungicide, 7-10 days apart, beginning when the disease is first evident. Damaged grass will recover if treated soon enough.






The best prevention for brown patch is aerate often, water only in the morning hours if additional water is necessary, remove excess thatch, and follow a fertilization schedule to help increase the amount of nitrogen levels in your lawn.



Dollar spots are most common to Kentucky Bluegrass, Bent Grass, and Bermuda in humid climates. They get their name from their small silver dollar-like shape, but can begin as the size of a small grapefruit. Usually looks brown or straw-colored in appearance. The spots may merge to form large patches several feet wide

Dollar spot is most common during warm, wet weather with heavy dews and in those lawns with low levels of nitrogen.

Not sure where this field is but it looks like what they are referring to in this article, poa annua grass.

It is not dollar spot, it would be brown "spots" not just different green "spots" of turf.

if its just a different color green it could be annual blue grass or perennial ryr seeded into a darker turf such as bluegrass. A lighter color green wouldn't be an indication of fungus.

I am agreeing 7 months later...its poa.
I am seeing that it was resodded with big roll sod. 4 feet wide and about 60 feet long. So therefore you can see some sod rolls from the sod farm were almost free of poa. And some were partially infested. Some heavily infested.
I would not be happy with the sod farm. Then again I am sure they could have spent more and gone to a better sod farm. However--now that the poa has gone to seed--perhaps the soil is permanently contaminated with poa, and better sod would not solve the problem.
