Lawn Question

All pre ems need to be watered in. Never reapply a pre or post em until you have proof it didn’t work.

I’ll post my question in here because it’s a lawn question.

I have a few spots in my yard to treat for weeds. I’ve got spots of VB, lespedeza, nutsedge, doveweed and other weeds. I treated the VB with MSM about a month ago and had good results. I’ve treated the nutsedge with Sedgehammer with unimpressive results. I’ve treated the he doveweed with atrazine with good results. And last year MSM did wonders on the lespedeza.

I just purchased some Celsius based on the recommendation of many on this board. Is Celsius the product to apply to take care of all of the weeds? Of note, I’ve still got all the aforementioned post-emergents in supply (plus Image and glyphosate).

My yard looks nice. It’s just that over the past couple of years, I like many others on this board, have become really aware of any and all weeds in our yard.

Thanks for your time.

I bought Celsius WG from Bayer.

I have used the Sedgehammer packets mostly.

I used a hose-end sprayer attachment one time and had better results. The name escapes me but I bought it at Clegg’s.

Is there a specific amount of Sedgehammer to add to my Celsius mixture?

I suspect that may have been “Image for Nutsedge” pre-mixed in an attachment bottle. I’ve used it in the past and it worked good for me as well.

I believe you add it at the same labeled rate in the mixture as if you using it alone - 0.9 grams in 1 or 2 gallons of water per 1000 sq ft for either spot or entire lawn spraying. For the individual packet Sedgehammer just follow those directions.

I have a similar question but about using MSMturf with Celsius Xtra. Of course, fairly mature VBW is the main target with others weeds mixed in. I know it was discussed but can't find the right thread. Found Xtra on ebay from $95, should be here by Friday so it's on this weekend!

As I recall you would mix both together at their normal labeled rates for the weed you targeting to control which in your case is VBW - those are the high rates listed on the products’ labels.

ronk has knowledge of this so maybe he’ll jump back in to this thread or you can start a new one for him to see. I seem to recall ronk suggested mixing the 2 for those that were having trouble controlling lespedeza b/c some were having trouble controlling it with either Celsius or MSM Turf used alone, as that weed is showing some herbicide resistance - personally I’ve not had a need to mix the 2 so I can’t speak from first hand experience.

Another lawn question, but this is dealing with pesticide application to your lawn, shrubs and surrounding structures. Which do yall prefer? Talstar, Bifen IT or Suspend SC Living in south Louisiana I mainly want to control mosquitoes. Ants, beetles and flies are a small concern compared to the mosquito problem especially after a rainy year like we've had. TIA

Talstar and Bifenthrin IT have the same active ingredient, bifenthrin. Both should be equally good following label directions for each product. Suspend SC contains deltamethrin and is another good insecticide - I use it indoors because it’s odorless and particularly good with spiders.

My subdivision is sprayed by BR Mosquito Control on a regular basis so rarely are mosquitos are an issue for me so others can guide you. But I will say I’ve tried the Spartan Mosquito Eradicator system (basically tubes with filled with yeast, sugar and water) and they did seem to work - produces carbon dioxide which attracts mosquitos into the trap.

Normal label rates. This is a strong mix and should only be used if normal mix PLUS SURFACTANT didn’t work. Lespedeza and spurge have been showing some resistance. Bermuda will yellow, centipede will turn purple, and St Aug’s growth will be stunted.

Thanks for confirming the rates for combined usage in St Aug.

I did find this quote from a year ago:
“ For a full 4 gallon backpack it is 3.8 grams of MSM and .51 ounces of Celsius. There are 3 main weeds where the combo is better than the stand alone product: VBW, lespedeza, and spurge. It is not a combo I mix often but if I've treated something and it just keeps hanging on or sections of the weed are starting to regrow then I use the combo.”

I'll be working a 2 gal volume (with surfactant) so need to cut the 3.8 of MSM in half and read up on the Xtra rate.

Just ran the numbers myself. You are correct at 0.65 grams per 1000sqft for MSM Turf. Thanks!

Xtra is basically a factor of 10 from MSM Turf. Recommended low/mid/high rates are 5/7.5/10 oz per acre. I will simply follow the spot application directions of between 4.8 to 6.5 grams per gallon, which is the mid and high recommendations.

So high rate application of both would be 0.65 gram/gallon MSM Turf (0.023 oz/gal) and 6.5 grams/gallon (0.23 oz/gal) Celsius Xtra with 2 tsp/gallon surfactant. Please, anyone feel free to check my math here. I'm thinking about backing off those numbers some so I don't stunt the St Aug too bad.

Here is the Celsius Xtra label for those curious.
Xtra

For Spot Applications Apply as a spot treatment to control individual weeds or patches of weeds. Mix 0.17 oz. - 0.23 oz of Celsius XTRA per gallon of water and add a non-ionic surfactant at 0.25% v/v (0.36 oz/gal or 2 tsp/gal) to treat 1,000 sq. ft. Spray weeds to wet but avoid spraying to the point of run-off.
