There any many roads to Dallas, but one of the best approaches for weed control in warm season grasses, even in the heat of summer, with the cheapest cost per application, is:

And here is how it works:​

In the Bermuda Triangle, you'll want:

1) A good pre-emergent like Prodiamine [Label] or Dithiopyr [Label].
2) Certainty for sedges. [Label] (Use the Marketplace forum and split Outrider for more savings.)
3) Celsius for all the rest. [Label]. Try buying it here, here, here, or here.

That's it. There are no temperature restrictions on any of the items listed in the Bermuda Triangle.

4) Get a decent sprayer wand to apply the chemicals.
5) Use a $10 gram scale to weigh out your doses.
6) Apply off brand RoundUp: glyphosate [Label] with a paint brush on anything that survives the Triangle, or use Precision Gel.

Depending on how large your lawn is and how bad your infestations are, the price per app with these chemicals is much cheaper than big box store options. That's really all you need. Eventually, your weed pressure will drop so far you can give your leftover herbicides to a friend or neighbor.

The initial investment is steep, but will pay for itself in time, while allowing you to put down less chemicals and have fewer weeds than with hose end applications from box stores.

What about this? It has the ingredient Sulfentrazone, but not sure if the percentage is enough.
What are y'all still thoughts with MSM as well?

There are dozens of products that kill weeds, but this thread is really dedicated to those outlined in the original post. Feel free to start a new thread about MSM or others you have questions about in the warm season subforum. :thumbup:

I would go with "verse visa". Spring weeds like crabgrass are tougher to get rid of while not hurting your growing grass, so you want a good barrier down then. Winter weeds are easier to nail because your grass is mostly dormant (in the south) and temps are cooler for cheap solutions like 2-4D. So, even rates during spring and fall are best, imo, but if you are going to go heavy at one point, I'd aim for the spring app to be heavier.

This is what I was thinking, but leaning toward going heavy on both now. I'm just inundated with crabgrass and goosegrass (I think), that just a heavy dose now and spring will do the trick.

Mixing instructions for the certainty states to mix at an application rate of 2 gal/1000ft.
I will be using a 1 gallon pump sprayer. So do i calculate the amount of prodiamine and celcius i will mix based on amount/500sq ft??? The more i read the more confused i get. Thanks!

I want to mix all 3 together since i am treating roughly 5000sq ft of yard with a 1 gallon sprayer. So if im correct i will be making 10 batches at a 1 gallon per 500 sq/ft application rate per the instructions for certainty. Right??

Welcome to TLF! :thumbup:

I understand what you are wanting to do, and it may work fine for you, just note that:

The Certainty label explicitly calls for 2 gallons of carrier per thousand.

The Celsius label states "For broadcast applications, use a minimum of 10 gallons of water per acre. For weed control in dense weed populations, control of weeds under adverse growing conditions, or control of mature weeds, higher spray volumes up to 60 gallons per acre should be used." I read that as they are not recommending a carrier rate higher than 1.38 gallons per thousand (60 gallons/acre) for broadcast applications.

Both of these labels call for use of a non-ionic surfactant. Prodiamine does not.​

That said, regardless of how much carrier you opt to use, or whether or not you add NIS, the application rates per thousand square feet are:

Certainty: 3, 4, or 5 small scoops (low, med, high)
Celsius: 0.057, 0.085, or 0.113 oz (low, med, high)
Prodiamine 65WDG: 0.83oz ÷ number of apps planned per year​

A couple final thoughts...

1) I make separate pre- and post-emergent herbicide apps because I rarely/never blanket spray post-emergents and I use different spray nozzles optimized for each product.

2) If you are committed to blanket spraying your own Prodiamine, I would highly recommend investing in a backpack sprayer. To be honest, I feel like you are compromising on multiple fronts because you don't have the right equipment for the job.

No worries.

I think several people here have mixed Prodiamine and Celsius with satisfactory results. I would consider doing that, then following up with Certainty spot treatments as needed. Do you know what weeds are you targeting? You should start a thread about your lawn in the warm season subforum so you/we can follow your progress and keep track of what you've done.

Im targeting all of them😂😂😂
I havent identified all of it, but i have a bad crabgrass and sedge problem. The broadleaf stuff has been easy in the past with scotts bonus s, but figured id use the good stuff from here on out.

Getting your Preemergent(PreM) down now is going to be the best weapon you have to defeat the crabgrass and Certainty will help with the sedges.

Can anyone tell me whether the herbicides Celsius or Certainty have expirations?

I think @Mightyquinn confirmed Prodiamine does not expire. I have enough Prodiamine for another 40 years. Does the Celsius and Certainty go as far?

I have seen group splits for PGR. Does anyone ever do group splits for Celsius or Certainty? Or is it not necessary?

Thanks in advance...

You are correct @TulsaFan, I called the manufacturer and they told me it had no expiration date as long as you keep them between 32F and 105F. I assume the same for everything else unless it clearly states somewhere on the label. My bottle of Celsius is about 6 years old now and still works and would assume the same for Certainty too.

I guess it would be up to whoever is buying it on whether they want to do a split or not. I love the stuff just because you can buy it and you always have it on hand to kill any outbreak of weeds you might get. I think the $85 I paid for Celsius back in 2012 has paid for itself many times over.

Does sedgehammer have a temp restriction?

Also prem, generally put down in March and then September? Using granual dimension here.

Not sure if it does, I have used it in the past with little to no issue, but I sprayed some last month and though it did put a good dent in the sedge invasion it did quite a number on my bermuda. I ordered some dismiss to give a try and see if maybe a blanket spray rather than spot treatment will have better results on the sedge. with hopefully less damage to the turf, I will mix in some FEature with it too.
