we have a yard that is kentucky blue grass and it has brown spots that are starting to form. from what i understand these are called dollar spots. from what i hear it is some type of fungus that causes this, which would explain it, the yard doesn't drain the best. i have done some reading on this , but would like to know what you pro's do, to get rid of these spots any input would help

If it is in fact dollar spot, there are two ways of dealing with it: 1 - spray with a fungicide. Daconil, benomyl and others work well on dollar spot, however, repeated use of benomyl will likely result in some resistant strains of dollar spot. A mix of benomyl and daconil will work for about 30 days (this is the cheapest method I have found, but there may be others. 2 - fertilize the lawn with 1/2 #/1000 sf of urea fertilizer + 4-8 oz. of a true chelate iron (don't use ferromec, I prefer Lawn-Plex) dissolved in water. This won't eliminate D.S., but will "mask' it by produing a better looking lawn. I've used the #2 method on bent greens with good sucess.
