Common Lespedeza in yard
Just came home after a month away and Common Lespedeza or Japanese Clover has overtaken my front and back yard. Does anyone have experience with Tenacity or recommend another way to fix this?
Thanks

I use either MSM Turf (methsulfuron methyl) or Celsius to control it, and those can be applied at higher temperatures but I’d apply early in the AM. You’ll get some yellowing of the turfgrass in this heat but it will recover.

Never used Tenacity but I read the label. Lespedeza control is not listed on the label. I don’t know if there is a temperature restriction on Tenacity.

I had a major problem with it as well and Celsius worked great.

Thanks for the tip.
Took an additional walk around and noticed some stiltgrass too.

Just bought some Celsius. How does it take to show results? I'm trying to control buttonweed, Netsedge, and carpet grass mostly.

You’ll see results pretty quickly on V Buttonweed and carpetgrass with Celsius, particularly in this heat, within a few days to a week. Make sure you use surfactant (spreader sticker) in the spray solution.

You’ll need a different herbicide to control nutsedge, I use Sedgehammer (halsulfuron) but I have also used “Image Kills Nutsedge” in the past and i was pleased with the results.

Surprising, the Celsius is turning the nutsedge yellow first. I haven't seen any signs from the buttonweed or carpet grass. I reapplied some areas this morning due to the first time I applied was late afternoon. After doing some reading, it is best to apply in the morning with the dew still on.

Will post results next week.

I know yellow and purple nutsedge are not listed on the Celsius label for control, but that doesn’t mean it might not cause some damage. Now, Celsius does effectively control Green Kyllinga which is a sedge, like “miniature” nutsedge. Control of green kyillinga, carpetweed and doveweed is the main reason I use Celsius, those weeds aren’t effectively controlled by MSM Turf. Otherwise I usually use MSM Turf, to control most other broadleaf weeds b/c i find it equally effective and it’s considerably cheaper.

I know I do see quicker results when using Celsius, usually within days, compared to MSM Turf but they are both very effective herbicides.

Make sure you are using the right concentration of Celsius as stated on the label for the weeds you are trying to control and mix a surfactant (spreader/sticker) in the solution - the surfactant is important.

I have it Mixed for Button weed and carpet grass. I did add surfactant as well. It’s only been a few days.

Understood. It is a systemic herbicide and those take longer to show results, but it will definitely control buttonweed and carpetgrass. You’ll see results shortly. Common to require repeat application in 2 or 3 weeks, certainly for the V buttonweed.

buttonweed starting to wilt hard. have not seen much results out of the carpet grass, which is what I need it more for.

Trying to recall from memory, it was a couple years ago, when I had scattered patches of carpetgrass to control and now that i think more about it, seemed it took a couple weeks or more for carpetgrass to die following Celsius treatment. And just seemed to fade away, but it seemed that even though it took awhile to die it stopped growing.

I did a quick search, and some guys on a lawn forum (lawn maintenance people) confirm it will take 2 to 3 weeks for carpetgrass to die after spraying with Celsius. Here is the link, read down a 1/2 doz posts or more for those comments. LINK Back to that old “be patient” quote. If you’re sure it’s carpetgrass its going to kill it.

Ive spot sprayed in the past and frequently throughout the summer with Ortho Weed Be Gone

Would Celsius be more effective and prevent the need to spray throughout the summer?

Celsius should nuke lespedeza in one shot at the right rate

Celsius is a post-emergent herbicide so it’s not going to prevent weeds. Depending on what types of weeds you are trying to control, consider using a pre-emergent herbicide in late winter/early spring and fall, it won’t eliminate weeds but certainly helps control annual weeds and reduces, not eliminates, the need for spraying.

re: Common Lespedeza in yard
I use dimension every spring and fall with atrazine before the spring run

Thinking of trying another brand...maybe Tenacity.

Any recommendations? mature centipede turf

That’s what I use, both late winter and fall, plus some simazine in the fall. I’m thinking of trying a late spring application of Barricade pre-emergent to help control doveweed, which is becoming an increasing problem in my yard, and which Dimension does not control. Not used Tenacity but does seem to have both good pre-emergent and post-emergent control of a number weeds, but not the 2 I’m having the biggest issue with - doveweed and to a lesser extent nutsedge.
