re: Dealing with brown patch in the yard...

In Saskatchewan isn't all of your grass brown (or white) now?

Seriously, I've used several different brands of fungicide (Bayer, Ortho, Scotts) and they have all worked. But it can take a long time for the grass to come back if the patches are large. Are you sure that it is not chinch bugs? The first time I had a problem I treated for chinch bugs for a few months and after it took out more than half my lawn I finally realized it was fungus. That took the rest of the year to recover (about 3 months). I've got St. Augustine which has runners so it comes back faster than most.

And I have to use fungicide every couple of months or so or it will come back. That may be due to having a lawn surrounded by woods which I believe is the source of the fungus since the attack is continuous.
