    I have a St. Augustine and have been geting rains almost daily. I don't know if I have gray leaf spot or the begining of brown patch. Any way it is most likely a fungis of some sort. Any suggestions?

    I also picked up a new account and mowed it for the second time today. It is cenipede. It looked like a healthy lawn but today when I showed up to mow it there where streaks in the yard from where the tires on the mower ran across the the grass. Kind of redish to brown in color. Not real bad but noticable. I think it is also a fungis maybe caused from the mower compacting the soil? Whats the answer? Or is this even the problem. There is no doubt it is showing signs of fungis in other places also. It too is getting lots of evening showers high temps and hunidity. You know, great Louisiana wheather. Any help would be greatly appriciated.

    God Bless

    Not sure about warm season grasses but when We have a sprinkler not hitting right and we drive across it is really noticeable where the tires went, especially with a red thread break out. Have you ferted lately? is your irrgation right? check the obvious first then post some pics so we can better help. hard to tell with writing what it is.

    I don't know what causes it, but centipede turns a different color where your tires run. I think all the centipede does it to a certain extent, but some more than others. I don't think it is a problem, but I could be wrong.

    Brown patch is a big problem with St Augustine. If you can post some pics it would be easier to diagnose.

    I hate to tell you this.....

    But if you are cutting fungus at one place, you can transport it and infect another place.

    I made the mistake of scraping my mower deck in my front yard. Then I was lazy and left the clumps there for a day or I have dollar spot on my St Augustine! I am treating it so it shouldn't be a problem. But you have to think about these things when going from yard to yard. Good point Envy!

    Yep... funny but not funny story...

    A few years ago I was invited to bid on a big new Lowes location.
    Everything freshly done.

    I got blew out pretty bad on the bid by a newbie.

    Well, it was a wet year that year and fungus started breaking out in a lot of places. Well, it was not to the point yet where this Lowes location would have been effected. But not knowing any better, this newbie tracked it in from somewhere else. It started out right where he parked and first hit the grass.

    Then it just kept spreading and spreading. He had a Gravely 260Z with that stripe flap thing that gravely has for the back of the deck. Over time, he effectively brushed it across every bit of the turf.

    In the past, fungus had not been an issue to speak of, other than brown patch once in a while. Nobody had a clue what was happening. In the end, the entire turf area was a complete total loss. I mean every bit of it got infected and died out from fungus.

    You bet, you can spread it from place to place with your equipment and with your shoes. Disinfect with Lysol before and after every cut.

    Most of the climatic conditions you mention are classic physiological symptoms for some type of soil borne pathogen.
    However, with out an accurate photograph I cannot say for certain yet what you have occurring is a classic outbreak of Pythium.
    At this time I do not think your soil temperatures are high enough, at a sustained level, to support any Rhizoctonia spp unless there exists underlying physical problems that has already stressed the turf.

    In English please!:laugh:
  10. Augustine has few if any 'fungus' issues. Only one I know of is SAD virus, and I've never come accross it in Hawaii.
    I would look to see if its Chinch. Cut the bottom off of coffee can push it down on the dead/yellow spot and fill with water. If lots of little black kritters (esp with little wings) float to the top in a few minutes you got Chinch. If its Chinch you got to get busy. Takes 14 days minimum to get under control. Need to kill the Nymphs or they will be back. And they thrive in HOT araes of the lawn.
    Without a pic we are all just taking stabs at your situation.
