    Can anyone give me a clue as to what is eating my St Augustine and what to put on it to stop them from eating it? I sprayed some Spectracide Triacizide last week but have some new spots where something has been eating. I mixed the correct amount but have to wonder if I screwed it up on the application. Any thoughts or advice on whether the Spectracide Triacizide is worth using or if I should be looking at trying to get something else would be greatly appreciated.

    I know these pictures aren't the greatest and I will attempt to get some more that give a better overall picture of what the entire yard looks like.

    I posted this same post in the homeowners section but didn't get any bites so thought I'd try here and see if anyone may be able to help me out.

    I have attached pictures in the the link below in the homeowners forum.


    Thanks again,
    Eric :usflag:

    Eric: I can't say for sure, but look like a fungas more than something eating on. Could be Clinch bugs. Does it look like the leaves are being chewed? Or Does the leaves pull out very easily from the stem. Pick a stolen where three leaves come come together and pull the middle one. Does it slide out or does it break? If it pulls and is sorta slimmy; you could have brown patch.
    If fungas is the problem that Spectricide is worthless....it that anyway.
    Do yourself a favor and before things get to far, get a professional out there from the County Extention Office to help decide the problem. We have several guys here from FL. Maybe one of them is close bye. Tell them your town?

    Looks like drought stress to me. We are in central Florida and with little to no rain, spot like that and worse are showing up all over.
    Below is the directs we are leaving with our customers to help them alleviate the problem on their yard.

    Beware of Drought Conditions

    Dear Customer,
    As in past years, we are experiencing drought conditions. One of the conditions associated with this is hydrophobic soil. This means the soil is water-repellent.
    This happens when we go long periods with no rain, which is needed, for good thorough saturation. A way to alleviate this problem is to apply either:

    Localized Areas Large Areas

    1 oz. 1 pound
    liquid dish soap dry laundry powder (non-bleach)
    per 1 gallon of H2O per 1,000 sq. feet
    *Water in thoroughly to activate.

    Try applying soap on an as needed basis or about once a week during drought. If your yard is compact in areas, this problem shows up more prevalent.

    Other problems seen with this are marginal response to fertilizer. It takes water for plants to uptake fertilizer. Where the ground is absorbing water readily, fertilizer response is very good. Where the ground has become hydrophobic (water-repellent) fertilizer is not taken up readily. This leaves blotches of yellow dry turf within green healthy areas.

    So to make sure I have this straight; I would mix 1 oz of liquid dish soap with 1 lb of dry laundry soap and 1 gallon of water all together and then spread it over the yard ? What is the best method of spreading this mixture?

    Thanks for the replies.

    No you don't mix the two.

    You can either mix 1 oz. of liquid dish detergent in 1 gallon of water and pour over the localized areas. Then run the irrigation or hand water behind it.
    Sprinkle dry laundry powder (non bleach-non phosphate) out at a rate of approximately 1 lb. per 1,000 sq. ft. to large areas, followed by a normal cycle from the irrigation.

    I will edit the post above. When I copied and pasted it from my word doc it shuffled the info.

    I couldn't edit it.

    If the moderator can remove it to prevent anymore confusion I would appreciate it. Sorry for the inconvenience

    Thanks for the update and I am glad I asked; I will give that a shot and see what happens. It's frustrating to say the least to have a mostly nice looking yard and then have this big spot creep up on me.

    Yes, your right Greg. That is drought stress. I live in central FL also. It's everywhere right now. Truthfully, when we experience conditions like this, it's almost impossible to get every area covered with the irrigation system. It's not your fault, just terribly dry conditions.

    Well, my lawn smelled like green apple dawn dish soap for a while until it was watered in good. We'll see what happens. Any idea how long it should take to see a difference in things?

    Thanks again for all of the help; it's greatly appreciated.

    Take Care,

    If the grass still looks like the pictures and you ran the irrigation behind it for approx. 3/4 of an inch you will see results in the next day or two.

    My yard smelled like Summer Breeze Extra on Weds. night when I put mine out.

    Sam's Club has 0ne Gallon Pink Dish Soap for $ 3.97 a gallon. At this price I am applying about 3 oz per thousand sq ft or a gallon an acre.
