i sprayed a cocktail today. milk/molasses/baking soda + nitron. i hope the milk and baking soda helps a little.

It might me in the same family of rust. Seems like there is different kinds of fungi within the rust family. I couldn't find any other disease pictures that match up quite like lawn rust does. The University of Michigan has a picture on their website that looks very similar to mine.

I'll try applying some milk tomorrow. Hopefully it will keep it at bay before winter dormancy hits.

Some cocktails work, and others don't. The above one looks OK except for the baking soda. Baking Soda works by changing the pH on the surface of the grass blades. Mixing it with other things tends to cause the (alkaline) baking soda to react with the other ingredients (possibly lactic acid in milk?). If the pH-lowering effect is neutralized, it doesn't work.

i was pondering this and thought i may have neglected the acid-base interaction, but we are both right andy. Lactose is primarily found in fresh milk, while lactic acid is produced after fermentation, or the breakdown of bacteria. Initially, it won't affect the cocktail's ph keeping it at a basic ph, but when bacteria starts breaking down the lactose into lactic acid, the ph will start turning more to the acid side. i don't think i used enough milk anyway to drastically move it to the acid side, and i think the basic properties of the baking soda should have an initial effect on the rust before acidity happens. i think i'm ok with the cocktail.

edit: haha funny to see i got a word banned

Guys with rust or some rust-like symptoms-- does it look like this up close?

Yes, i would say that closely resembles my pictures of the symptoms which are located on page 1 of this thread.
