Welcome to the forum, @antiweed!

No, I would not mix all those products at once. That is a crazy hot mix and many of them have the same active ingredients. I would start with the Prodiamine and water it in. Post-emergents would depend on which desired grass type you have.

 

Hi@Redtwin, thank you. Can i mix Prodiamine, 4-Speed XT, Sublime, MSM with Tenacity? I thought MSM can kill burweed. I don't really have much of any grass really but I'm considering Bermuda or Zoysia once I kill the weeds off

 

Why not just use Round Up and be done with it?

 

because i think i do have some grass left plus i was just going on seeding plan to cover the dead weeds areas - i guess... i'm no where near a gardener. not even remotely close

 

What do you plan on seeding? And if you do plan on seeding why would you apply Prodiamine?

 

bermuda or zoysia grass. I thought to kill the weeds first and then see what's left then, go throw some grass seeds. Prodiamine is effective in killing crabgrass? so i could do an effective herbicide combo mix that would kill the garden variety of weeds in my yard

 

Keep one cultivar not a salad bar. Please do more research, your at the right place! Read product labels, and learn about the products and how they work.

Once again, your at the right place, post your application rates to get feedback to ensure your on the right track. Mixing a soil and foliar products together is just plain wrong and will not give you the results you want. Applying a pre emergent before seeding is once again, just plain wrong and setting yourself up for failure. Tenacity is for cool season grasses.

so you're saying i need to put down grass seed first before applying herbicides to kill existing weeds? oh crap! what is the alternative to Tenacity for warm season grass?

 

Prodiamine does NOT kill crabgrass it prevents it from germinating along with any seed you put down. If it’s hot outside, all you need is Celsius and Certainty. If it’s still cool outside just use a Southern 3-way herbicide. You are completely overthinking this, also, start reading the labels on all these products you bought, they will answer a lot of your questions.

 

Southern 3-way herbicide

Can 4-Speed XT be considered as the Southern 3-way herbicide?

 

Sublime and Tenacity have the same AI: Mesotrione
Sublime and 4-speed XT both have Triclopyr
MSM is it's own monster and shouldn't be mixed with any other AI (my opinion for new applicators)
Triclopyr and Mesotrione are very bad for any existing bermuda or zoysia you have.

I'd start here: Bermuda Triangle and then read through the Bermuda Bible: The New Testament

Most of the stuff you will read in those two threads applies to both Bermuda and Zoysia.

 

If anything, I bought 4-speed XT as the 3-way herbicide base, hoping to mix it with 2 other combo to kill the garden variety of weeds i have. Please tell what herbicides (Prodiamine & celcius is understood to be kept) to keep as pre/post ems to maintain weeds at bay. I just want them gone especially the burweed and dollar and crabgrass and...ughhh!

 

Can I mix Tenacity, Sublime, NuFarm 4-Speed XT, Prodiamine, QualiPro MSM and small packet of Celcius together with ammonium sulfate, surfactant and blue dye?

I have a wide variety of weeds namely burweed, dandelion, clover, dollar, quackgrass, crabgrass and a bunch of others (I don't even know their names but I could tell they're not regular grass) sprawling all over 10+k sqft yard in central Texas.

I've found that the different active ingredient (AI) in herbicides treat specific weeds so I just went and got a bunch of them hoping to kill them all in one fell swoop.
Please help! The temps are rising so I would need to apply them here shortly.
Thank you

You left out Tabasco sauce.

 

@antiweed, it sounds like a lot of your products are geared towards cool-season grass. Instead of 4-speed XT, look at Speedzone Southern. It would take care of your burweed and dollarweed. Again, if you're not going to seed, start with the Prodiamine then the 3-way or 4-way. If you are planning on seeding, kill it all with Glyphosate and start with a fresh slate.

 

Thank you for replying @Redtwin. I didn't know any better...I googled the comparison Speedzone vs 4-speed XT and found 4-speed to have a higher content of 2,4-D (the 1st active ingredient) in both herbicides. They both say can be used on Bermuda. So do i still keep the 4-speed and is it ok to mix with Prodiamine? Am I returning the MSM too? oh gawd the amount of return shipping and restock fees im going to be hit with... No, I don't have the energy to start a clean slate... i was just going to throw grass seeds once the weeds die off and let the rain take care of 'em and pray that they eventually grow into grass and overcrowd the those darn weeds

 

Looks like the 4 Speed "can" hurt hybrid bermuda but I think that may be at higher temps but I'm not 100% sure on that. The 4 Speed is just for broadleaf weeds according to the label. Who recommended you to buy all these herbicides? Just seems like you jumped the gun a little bit. You need to figure out what your plan is for the year before attacking anything. Take a step back and think this through a little bit more. How big is your lawn? How much shade is there? Do you have irrigation? What kind of lawn would you like to have? What is the lawn going to be used for? These are just a few questions off the top of my head that you need to ask yourself and/or answer them here and we can help guide you to where you want to go.

 

believe it or not, i bought all these herbicides from reading too many posts in this forum and i read from cool and warm season grass... and naively combined them thinking that I'd make the most effective combination.... a huge mistake that I'm paying dearly for right now. had 1 goal only - to be rid of the weeds that's taking over, crabgrass, quackgrass, etc and realized that I needed to put grass seeds down so it won't be muddy. grass lawns do hold the soil together somewhat

Front and back yard combined is ~11,000+ sqft. no irrigation, no shade. tbh, not a garden/lawn person at all. golf turf lawn is aesthetically pleasing but I don't have the energy nor the budget for them. I do like grass that's thin blade (bermuda/zoysia/fescue) and boiled down to either bermuda/zoysia cause less maintenance. the lawn is there because it's there, no plans. (p/s I'm not trying to give a smart a** answer).
😩

 

The 4-speed has Triclopyr that can only be applied to dormant Bermuda (someone correct me if I'm wrong). In Central Texas, I would bet your turf is not fully dormant. Can you post some photos of what you're dealing with? I'd keep the MSM but don't apply it just yet. If possible, I would go ahead and return the 4-speed and the tenacity.

 

So return 4-speed and buy Speedzone Southern EW? There's many different versions of Speedzone. I'm asking... which is the most effective one to kill those hard-to-kill weeds on warm season grass?

Do i need the ammonium sulfate? I read that it tricks the weed to thinking it's food and therefore accelerate its death. I got it eventho I'd already gotten surfactant...I blame my insanity on them weeds!!! Is there any point in keeping ammonium sulfate?

Yes, keep the AS. You can mix it with the herbicides but I honestly would wait until there is no more danger of a frost. You really don't want to push new growth until you know the cold is over. You will definitely use the AS throughout the growing season though. Do you know what kinds of turf grass are currently growing in your yard (if any)? Photos are super helpful showing the general area and an up-close shot of the desired turf and any problem weeds. Based on your input, I would recommend nurturing what you have. Most likely, there is some bermuda in there somewhere. If there is any bermuda at all, you can get it to spread pretty easily.

 

@Redtwin Did you manage to see all 13 pictures I posted? So far, keep the Prodiamine, MSM, Celcius, AS and surfactant. Am I getting Speedzone Southern EW to replace 4-speed XT I'm returning? if yes, then, what is the herbicide combo mix I can do right now to keep the burweed and garden variety weed out? I will follow rate application on each label.

sorry, no, I don't know what grass or even any was cultivated. Your guess would be as good as mine. I haven't bought grass seed yet.

 

@antiweed, my bad. I completely missed those posts. I would start with just the Speedzone with surfactant right now. I'm pretty sure I see some bermuda in there and considering you are in Texas, it's probably there even if you don't want it there. I think you still have a good chance for another freeze so I would go super light on any nitrogen you add to the mix. Maybe do a 1/2 lbs of AS per gallon per 1000sf (.11 lbs of Nitrogen/1000sf). I'd go with the 1oz rate for the Speedzone but probably not much issue bumping it up to 1.5oz/1000sf if you really want to get medieval on the weeds. Give it a few weeks to gauge effectiveness and adjust fire as needed. It's going to be slow in the cooler weather but the surfactant will help a bit. I really discourage seeding warm-season grasses so you'd be OK putting down the Prodiamine now. You can mix it with the Speedzone if you want but I would wait at least 24 hours before watering it in. The Speedzone label says it's rainfast in 3 hours but give it a whole day. Start there and we can start recommending other products once you have cut back on the easier-to-kill weeds. Be sure you calibrate your sprayer to spray around 1 gallon per 1000sf. There are lots of YouTube videos on how to do that. MSM is a good one but very concentrated and will kill trees. You want to make sure you have your spraying technique down to a science before mixing that stuff. A very little goes a very long way with that. It'll probably be the only thing that will take care of those holly saplings. The cool-season grass you have throughout will not like the Speedzone and will naturally die out when the summer heat kicks in. You can prevent them next season with the Prodiamine. If you decide to mix in Prodiamine, I recommend doing no more than .41oz per 1000sf. That's 6 months of protection. Again, you can adjust your plan as the season progresses and you narrow down the weed pressure. Good luck and don't be afraid to ask any questions.

PS: Just to be clear... don't spray the MSM or Celsius yet.

 

@Redtwin Thank you!!! I will go buy speedzone right now. It'll take a few days to get here.
Is it an issue if I bought Speedzone EW 20oz instead of Speedzone Southern EW 2.5G ? The price is insane $253!! 2.5gal is a LOT. Amazon do not sell Speedzone Southern in 20oz. Posted the 2 AI ratios below. Is Trimec Platinum better of the 2 Speedzone? the manufacturer's website seems to promote Trimec Platinum.

So far, my understanding; the combo mix is Speedzone(1.5oz/1000sf) + surfactant(1tsp/1000sf) + AS(1.76oz/1000sf) + Prodiamine(0.37oz/1000sf).
I converted the Ammonium Sulfate granules 0.11lbs to oz. I think my measuring cup is in oz.
Pls correct me in combo mix

 

I think if you want a weed free lawn, it' going to take some effort on your end to get it there. One of the keys to a nice lawn is consistency, you have to be consistent on watering, mowing, fertilizing, weeding and anything else that comes up. There are no special tricks or potions out there. I would like to see a wide shot of the lawn to really see what we are dealing with here. Not sure how much actual grass you have in there and it may take a few seasons to get looking good. If you plan on seeding, just know it's not for the faint of heart as you will have to baby sit those seedlings for at least 2-4 weeks after applying it making sure it's not getting too much or too little water. You just can't throw the seed down and walk away.

 

I think the Speedzone EW will work. I've never used MCPP, though. DoMyOwn.com or SiteOne generally have the best prices in my area on lawncare products. DoMyOwn ships really fast and SiteOne is in person so you get it immediately. See if you have a SiteOne nearby. I will price check Amazon but they are usually not the best price.

Your mix should be Speedzone(1.5oz/1000sf) + surfactant(1tsp/1000sf) + AS(8oz/1000sf) + Prodiamine(0.41oz/1000sf)
This is assuming you are using granular AS (21-0-0) and Prodiamine 65 WDG. Make sure you have your sprayer and walking speed calibrated.

Like mentioned above, this is just the first step and isn't a one-and-done application. Do you have an irrigation plan? Even the drought hardy grasses are still going to need water, especially if you are pushing them to spread. How often will you be able to mow?

 

Yes, there's a siteone store. Speedzone Southern is #1 choice, correct?

 

I sent you a DM.

 

Dithiopyr which is a pre emergent does have some post control on crabgrass (I think it was up to 3 tiller stage) but I would not base my decision on its post properties.

 

It's confirmed that I don't have any grass left, all that's growing are seasonal weeds all over yard. bought speedzone EW, no stock of speedzone southern. at a loss on what to do 😩

 

If there is any grass in there it's most likely dormant so it would look dead.

 

What is your plan after all the weeds are gone and you have nothing but bare dirt? You are still 2-3 months away from optimal seeding weather. I am assuming sod isn't an option?

 

my cheapest option - seed, one section at a time and then, slowly work my way? I posted a thread asking what type of weeder tool to get the gazillion weed growing in my yard without breaking my back. going to have to do a make shift sprinkler (will have to find YT video) since i have no irrigation.

My thought was to kill the weeds off first, come back with a hoe and start digging out dead weeds in a section, spread zoysia seed (pls recommend a reasonably priced all-in-one) (if i need to mix grass type in order to have grass growing all season to choke out the weeds, I'm open - low maintenance)

Appreciate any guidance (step-by-step) that anyone can provide. I can put in the elbow grease, just need someone to spell out what it is I need to do.

Just noticed the speedzone I got has expired - very old stock - need to return... ugh! Can I replace with Trimec? I'm sorry to ask again, what is my combo mix now that I barely have any grass. Do I still use the Ammonium Sulfate?

 

If you barely have any grass then go get some glyphosate concentrate from the big box store. As far as establishing grass, I would recommend sprigging vs. seeding. Do a search in the journals for "sprigging". @WillyT @Humbert810 @Chadwicktr @RayFinkle and @doodoo are some really good ones! @doodoo started his project in the late-winter/early spring so check that one out first.

 

Your combo mix is Round Up.

After the weeds die in the area you are going to plant, rent a verticutter/dethatcher from Home Depot or a local rental shop and go over the lawn with that machine. It will pull up the majority of the dead material and loosen the soil for a good seed bed.

 

I think you have two options.

1) Spray either your 3way or metsulfuron, wait a few weeks, see what your lawn looks like, and reevaluate, if there is really enough grass to keep trying battle remaining weeds and to save the grass. If not worth saving, then just switch to option 2.

2) Spray Roundup (glyphosate) and kill everything. Then put down the grass you want. Zoysia you’ll need to sod or sprig. Bermuda, you can seed some cultivars, others need to be sprigged or sodded.

 

Can't do sprigging unless I buy sod, which isn't an option @bobthestump. I'll go with option 1. Dissapointed to hear I can't grow zoysia from grass seeds. Can someone pls recommend the type of grass mix I can lay down? Scotts or Pennington? OR where can I get Zoysia sprigs for cheap in Central Texas?

 

Just a hint I completely agree with the roundup (glyphosate) to clear out everything. Avoid any roundup or other glyphosate product with diquate dibromide. I know this first hand and just had an CE class on it. Diquat burns out the leaf before the glyphosate can make it to the root. The PHDs say they have proved this in lab tests and I could have already told them it was true from real world experience. Or don’t and let a lot of the weeds regrow from the roots. I’m all about doing your own thing.
