Hey guys, newbie here.... Dealing with a recent outbreak of rust on my side yard which is slowly creeping into the back. We recently moved into our newly build house so the lawn is still relatively new, installed in mid June. Been working hard to get it looking presentable and I want to stop this in its tracks before it continues to spread without harming the young lawn. From what I'm reading hitting it with N seems to be the way most people go. My concern is that it's been very dry in Pittsburgh the last few weeks, and despite only being in the low 80s and persistent watering I am getting very dry areas in the lawn which are appearing to die out (very straw-like and tangled together in areas). I'm afraid that the N application could overstress an already stressed out lawn. Thoughts? How would you guys treat it?

Thanks for any help!!

Here are some pics of the trouble spot. For comparison I've attached the mostly healthy front and back yards.

I always get rust on grass seeded before august, and I don't worry too much about it.
This tear I started spraying it with a fungicide.
Grassdaddy reports that he boosts the damaged parts with N to make the grass grow it out.

A spoon feeding of nitrogen helps. Water the lawn in the am only. Bag your clippings and clean the mower deck (it spreads). If all of these dont do it, then fungicide.

I've had this problem come and go all summer long. I hit mine with Milorganite (and Scotts Fungus Control which i read later doesn't stop rust) 2 weeks ago and its gotten worse and now spread everywhere. I ordered some patch pro propicanazole, hoping that will help take care of it finally.

This says for garden, but the label has the instructions for lawns (7oz/gallon into 500sqft). The ai is Myclobutanil.

You could get it at lowes:

You could get larger qty of Myclobutanil online (eagle 20)

Awesome, thanks for the input guys! I think I'm going to try that spectracide for the infected areas to hopefully stop it from spreading and apply some more nitrogen to help it grow out. We'll see how it goes

Just walked the dog around the block for the first time this week, most everyone's lawns are taken over by it. Its horrible! Never remember this happening before. Ben humid all summer long.
