    Ive looked through the books that i have, and i can not figure out what this may be. In approximately 40% of one of my client's lawn, there is a fungus on the blades of the grass. There are approximately a dozen patches of the fungus on each blade. From a distance it looks to be just drough stressed grass, but i noticed the fungus powder on my deck, and it appeared orangish, almost a rust color. What could it be, and how could it be treated (yes, im liscensed;) )

    I am warm season turf so I can only guess you have RUST,(Puccinia). Macozeb should help cure the problem. Add LI 700 by Loveland and it will work much better.

    Also sounds like RUST to me Mac.... RUST is the biggest culprit here on the moist west coast and is usually taken care of with an extra shot of fertilizer and bag the clippings... It is unsightly but usually doesn't do any harm to the turf... but Red Thread could be next if left untreated... Just juice it up a bit and let it outgrow the rust and all should be fine in a couple of weeks...

    Good Luck, Clay

    Sounds like rust to me also. In the past, we've had this problem extensively on our recreational fields. Both 4 Flowable Mancozeb and Bayleton are labeled for treatment.

    Mac,
    It is definitely RUST!!! It's running rampant here in N.E. Ohio. All the rain this summer is bringing out all kinds of disease problems.
