Is this widespread or isolated? It's really late in the year to apply fungicide to cool season grass. Fungicide is not going to kill your new grass but it's likely unnecessary. What are conditions expected to be over next 7 days? High temp, low temp, low dewpoint, rain?

 

Conditions in PA right now are ripe for fungus. Rust is everywhere. 5 days of mist rain with night time temps in the low 60s. My grass has been wet for 5 days straight. It is expected that these conditions will last 4 more days before the temperature drops. this temp drop will most likely reduce fungus risk.

The issue i have with this post is i do not see fungus bad enough in the pictures. At least not bad enough to spray fungicides.

Is he in PA? The old site used to show general location but I don't see it anymore. How do you tell the general location of posters?

 

He is in PA. it would be nice if posters would actually state where they are.

 

Sure, will do it going forward.

 

As a moderator, i have access to IP info. Unless someone is using a VPN. It is useful for general location. it usually points to the ISPs location.

 

Depending on what fungus your treating, propiconizole can be applied before or after seeding and some research shows it may help with germination.

 

You could add a signature or add location to profile, so if i hober over your username to the left it shows locations. Yours does show. I do not think it did earlier but maybe i missed it.

and yes if you have propi, i would apply even though the picture do not show bad fungus, I expect it could get worse before Wednesday's relief.

 

Sure, I will apply propi tomorrow.

I updated my location after viewing your comment. It wasn't there when I initially posted.

Thank you for the help!

 

Going into wet season, a group 3 like you mentioned isn't a bad idea. Spring i like to include a group 11. Azoxystrobin, pyraclostrbin etc. They are good for foliar as well as root/crown.
