Bonide Sedge Ender on Saint Augustine

10 years ago

So I tried reeljake's favorite - Bonide Sedge Ender on my Saint Augustine lawn.

dmt said when she used a product with the same AI it gave her grass a burnt orange effect (on SA grass). I think it was reeljake that said he uses it on his relative's SA lawn with no ill effects. I believe he used 3 oz/gal for spot spraying. That's what I used. I used a Chapin 61800 backpack sprayer with supplied fan tip. Yard was mowed one day prior (too soon? - didn't check label for that specifically, such a rookie). Temp was around 85 deg. Highs since application were between 85-90. Lots of rain prior to application (Hermine), no more water until my sprinklers did their thing 7 days later. About 8 days (and one mowing) later it looks like this:

Bonide Effect


Bonide Effect - Close up


The lower portion of the SA grass appears to be unaffected, every 'burnt' piece of grass I have specifically inspected branches off from what appears to be unaffected grass. So it may be unnoticeable after another mowing or two.

No pictures right now, but you can tell what yellow nutsedge you apply this to within a few days, the seed heads start turning brown, and then the rest of the plant starts to be effected.

It seems to have a much slower effect on spurge, areas I really blanket sprayed probably got more AI, and that spurge is browning. The spurge within good SA grass I was more careful with and some show some sign of effects, others none. I'll keep looking.

It has had some kind of effect on virginia buttonweed, but not sure of long term results yet. There may be some buttonweed in the close up photo.


I don't think it is labeled for doveweed, but the doveweed I have sprayed has turned a more sickly color.

Out of curiousity, in one area of my yard I am willing to test with, I tank mixed Sedge Ender (3 oz/gal) with Celsius (med rate). So far the grass doesn't seem to be any more stressed than when I used Sedge Ender alone.

To review, I am in Jacksonville, FL area with Saint Augustine grass.

Let me know if links don't work.

    That looks about right to me, but if that's too much stress just drop down to 2oz per G. You'll see results on the nutsedge even at 1.5 in my experience, just need a follow up app a week later

    I'm guessing I'll need another app anyway, but I'll wait until the grass has recovered.

    That damned spurge is a tough one. Even after a heavy spray, they don't really 'melt away' like other weeds. Their seeds are on the bottom of the leaves & fall like little grains of sand every time you touch the plant, so the preM component of Sedge Ender is your best friend on those. I'm going back to the old see one pull one method for those little red buggers, followed by a quick shot of SE

    The spurge is bountiful in my yard, but I am most threatened I believe by the doveweed, which I suspect is being vegetative propagated. It exploded after we finally started getting rain here. I need to use some Celsius on that soon.

    I had to go look that doveweed up & wouldn't ya know I pulled 2 or 3 pieces of it this afternoon--I was wondering what the heck it was. Is Sedge Ender labeled for it?

    I find sedge ender and sedgehammer extremely effective products but if area is a low point in your yard, gets hit persistently by sprinkler or if you have a lot of rain, that sedge is coming back, for that reason, I pick my battles and focus on areas in garden beds and leave lawn alone. I have a big yard so cost is a consideration . Both products are very expensive IMO.

    I couldn't find doveweed on the sedge ender label.

  • 10 years ago

    Grrr. Guess I'm buying some Celsius

  • 10 years ago

    Well it did have an effect. I wonder what full rate would do. I'll try and post the pics tomorrow, I took a before and one week later photo of the doveweed also.

    Dang, this doveweed is best controlled with 3 & 4 way mixes including my least favorite 2,4D. That is not what I wanted to hear.

  • 10 years ago

    Ugh...

  • 10 years ago

    @reeljake lol just add this to your mix and yellowing should be no problem.

  • 10 years ago

    NICE. I was planning to add a dollop of Microlife fish juice to the mix cuz it has iron & kelp meal, but I can just paint it! Classy.

    In reality, I'm going to try spectracide weed stop (2,4d, dicamba & mecoprop) diluted to low strength in the tank with a sulfentrazone & prodiamine kicker from Sedge Ender at 1oz per gallon. That a 4-way kill plus preM. Hopefully it doesn't blow up in my face & burn my eyebrows off turning my lips a radioactive neon yellow. I'll start a new thread with results. Stay tuned.
