    Greetings,

    I live in Newnan, GA (30265), and just since my last mowing (a week ago), I have developed several spots of dead grass in my Bermuda grass. We have had a lot of rain this summer, so watering is not a problem. I have not noticed any grub activity with my own inspection, but I really am not sure what to be looking for, either... I was thinking maybe a fungus or some such? I am attaching pictures so you can see what is going on. Please let me know if anyone has any ideas, or has seen this before.

    [I apologize if I have posted this to the wrong group...]

    Thanks,

    Jay De Leo

    This does not immediately appear to be disease IMO.

    When was the last time the lawn was fertilized? And exactly what was applied?

    Your dead spots are mostly along the driveway in a single path. Just wondering if possibly fertilizer was over-applied.

    I dont think it is a fungus either, most likely insects / grubs.

    It has been since the beginning of Spring since I fertilized, so, I do not suspect the problem to be over-fertilization. I believe I applied Scott's turf Builder with Weed Control.

    As I said in the original post, we have had plenty of rain, so I have not had to water additionally.

    Before a week ago, I did not have this problem. I mowed the lawn last weekend, and these spots formed soon after.

    Thank you for your help,

    Jay De Leo

    I have not had my driveway pressure washed. Any other thoughts?

    I'm still leaning toward either insects/grubs or a fungus...

    Thank you,

    Sounds like a good time to utilize your Georgia Cooperative Extension Service. They have an office in every county of the state.

    You might call your local office and have an agent diagnose your problem.

    Either way, it sounds like you or someone needs to get a shovel and start checking for excessive grubs. The japenese beetles indeed have been laying eggs recently, so that could be your problem.

    Might be a good idea to apply an insecticide targeting your grubs just in case. This is the best time of year to get them.
