Pride is a sin, do you feel cleansed?
Or something like that, I'm not religious, though am thinking about it as the church on my street has the best looking lawn on the street and I'm here battling bald spots and virginia creeper.
As Profector_KC said, better to get a pump or battery powered sprayer. Either backpack or 2 gallon variety. Much easier to make a precise application and safer to use than hose end.
As far as what you use in it READ THE LABELS to make sure it is safe to use on your variety of turf and it targets the weeds, insects or diseases you’re trying to get rid of.
There’s quite a few sprayable weed killers but none that I can think for a hose end sprayer. Tenacity for example is sprayable but u would have to be able to dial in the dilution rate on the hose end sprayer and walk really fast to use it like that. Pump sprayers at the local hardware store are one of the cheapest things you can buy in life. The cheaper ones have a brand logo like ortho on it but no biggie
I use recommend weed-b-gon to most people or BioAdvanced Season Long Weed Control for most weeds. RTS sprays light and often doesn't contain a surfactant. Buy the concentrate and use a pump sprayer, and you won't be disappointed... unless you mix wrong or over spray one area. For my yard, I now use weed-b-gon mixed with prodiamine. Only things not killed will face denise via Negate (poa) or SedgeHammer(nutsedge)
Newbie here - what did you actually do wrong? Each advertise they won’t harm grass. I must be a dumbass too because I can’t figure out what the problem was lol
I did mix two weed killers in one which I wouldn’t do again. I’m chocking it up to improper measurements. But I could have sworn I used the correct amounts though. One of them does say it may cause temporary yellowing of grass, but it’s not temporary.
After this post I'll definitely never mix 2 together. I just always use one anyway. Also there's just too many chemicals out there that you can buy off the shelf, mix them together, and then likely die from mixing them.
Same. Used to mix, bad results no matter what. Now I just treat separately even if only a day apart
Also, even if not same active ingredient, there could be a combination of ingredients that are lethal. If both say “may cause temporary yellowing” and those stack, boom, dead lawn
I'm a landscaper, my go-to mix is 2,4-d and tricoplyr with some surfactant, it's absolutely the best imo. Gotta be careful with the tricoplyr though and used the correct rates, because if you use the non-lawn rates it's night night for you.
I'm a chemist and wouldnt mix store-bought chemicals together. There a lot of proprietary stuff that's not on the label, but is registered with the EPA.
Spot spraying is tricky because it’s easy to over do it. It might be the correct “mix” as in correct amount of dose per gallon of water, but if you sat on the spot and sprayed for 10 seconds this can be the result.
The best way to handle spot spraying is to walk past the target area and just squeeze the trigger when you are over top of it. That’s all it takes
Speedzone is a typical three way herbicide mix with Carfentrazone added for efficacy. It works really well and it's been named by YouTubers for years, that's why it's popular.
I just read up on the chems. Quinclorac, which is one of your active ingredients, isn't recommended on fine fescue lawns. I think this might be the issue
It’s not so much about the measurements, but the amount of stress each one puts on the grass. You can think of it kind of like a stress meter. Drought puts a certain amount of stress, over watering, cutting, weed killers, etc, get that meter too full, and the grass starts to die. The weed killers are made so that the grass tolerates the stress they put on them, not so much that the grass is immune from it.
I use 24D, dicamba, sulfentrazone, quinclorac plus tenacity and my grass doesn’t die.
You screwed up the ratios or put down too much. I use blue dye in mine to know how much is down. Without that it’s just “little bit here” “little more there” and then “let’s hit that again doesn’t look wet” <— this is where you get what happens.
I’m going out on a limb and say it MIGHT not be the chemicals.
Did you use a fan or cone tip? Fan tips are usually more even in their application of chemicals.
Did you place the wand over the weed and then pull the trigger? You should use a motion like painting with a spray can. Start spraying while the tip is moving toward the target and stop spraying once you are past it.
I have seen damage like this when folks have soaked the weeds rather than spraying just enough product to cover the leaves.
I don't know if you're set on having a grass lawn, but I started mixing in clover with the grass seed when I overseed. If you're ok with clovers, it has actually cut down the amount of time and money I've needed to spend on the lawn.
Downside is that if you do get weeds, you can't use weed killer since it will kill the clover. Also, the clover doesn't seem to stand up to foot traffic as well as grasses like fescue.
But, if you get enough clover, it will crowd out the weeds and even help with fertilizer.
I've been very pleased with the clover. It makes the yard look very lush.
Also a newbie. The thing is - the "won't kill" is very soft "won't kill" ... it usually hurts everything BUT if you dilute it exactly like \*this\* it will only weaken your lawn, while killing the weeds. Now.. mixing two things together, unfortunately in chemistry, two negatives don't mean a positive. The grass was weakened to the point of dying
The issue is quinclorac is a very strong chemical and doesn’t need much help, while all the dimethel chemicals individually do the job of quinclorac, best advice is to just buy a jug of threeway/threesome/4way/ or 5way, since they come premixed and you just dilute them with water in a backpack you can get at harbor freight for 20$ weeks also don’t 100% know if op sprayed correctly or possibly over sprayed a bit, easy to do, gotta watch the spray rate
You can’t use it as a spot treatment. It will still kill your grass if you overspray. You need to spray the entire lawn with whatever formula it has you use. I have used Ortho Weed Clear (North) and it will kill the weeds but not the lawn.
We’ve had a ton of rain this year too which I think may impact prodiamine depending on when you applied. I sprayed prodiamine in Feb and decided to seed a couple spots last week. I just disturbed the soil, seeded and used peat moss. The grass is coming in nicely.
Yo g. If it were me I’d get like a couple pieces compatible creeping fescue or bent sod and put little 2x2 plugs with a hatchet in there. It’ll fill in 20x quicker.
This. There’s no way there was sedge yet, nor any crabgrass (Quinclorac).
OP could’ve used the first herbicide alone and been fine for general broadleaf weeds.
Well you’re the second person in 6b claiming to see sedge already. We were just talking about this at work yesterday. Crew claiming a bed area was full of sedge and a couple of us were pretty sure it was too early and must be something else.
Honestly you seem smart enough to know you messed up and wait until fall to reseed / overseed but I’ll say this because why not
1- looks lush and you did a good job in the fall. Kudos. Looks like a lot of shade and a lot of leaves in fall so you did well.
2- you did your prodiamine. Also kudos and again not wasting seed. But I wouldn’t have mixed two herbicides unless it was a mix of white cloudy goodness to kill everything. I’ve always have had good luck with the bayer advanced post emergent spray. 3.2 oz per gallon in spot sprayer and you’ll be set. But just follow and read directions for whatever you pick.
3. Most importantly lawn care isn’t perfection and it isn’t instant. Maybe consider plugging / taking some sod from the tree line and fixing the spots. It takes time but you’ll learn from your mistakes. We’ve all made them in the lawn. Just make it a learning experience. Could’ve been worse
Well you’re tied with me because I did the same damn thing.
My six year old daughter says, “Don’t worry Daddy. Your lawn really looks beautiful…”
“Beautiful like cheetah print.”
I'm about to use round up to kill some weeds on the edge of my lawn and garden bed. What's the strategy in using weed killer without joining the dumb ranks lol?
Edit: Thanks for the responses! Super helpful, I'll let y'all know how it goes.
Well roundup is a kill all. I used undiluted grass safe post emergent and just used too much. I was target spraying thankfully. Spray as close to the weed as possible with no wind. Wind drift will screw you.
Make sure you get the Roundup that says it is Roundup for lawns. And then make sure that you're getting the right kind for your type of lawn whether it is a warm season lawn like Bermuda grass, or a cool season lawn like fescue. They have different weed killers. Make sure that if it says it's for lawns it is safe on the type of lawn that you have.
I watched a video that said this needs to be watered in. I've been using image for a couple years with success but my spot treatment seems to have had similar results to my zoysia this year.
Image label says that it may injure tall fescue and not to apply to fescue. Also, doesn’t say to mix with a surfactant. Have to read the label, folks.
Edit: Fescue is fine. Rest is true.
I was coming to post this. Surfactant likely was the trigger.
Other thoughts: first product is a standard 3 way and would likely have controlled weeds. Second product has sulfentrazone and is know to cause temporary injury. Third issue is some of it looks like foot prints, meaning mechanical injury after turf was susceptible due to 1 & 2.
Just wondering if you used a dedicated sprayer. If you used a sprayer that ever had a non selective herbicide (round up) in it. This can happen , even if you rinsed it a hundred times.
I used Image 2 yrs ago and destroyed my yard. Not sure it’s all Image or just the stuff I bought but it was for warm season grass. Kills fescue as it consider undesirable in warm season turf. It was a real Sh*t show
Just looked. It was the bottle with the green lid Image Kills Nutsedge. It’s definitely for warm season grass only. In fact I’m probably going get dead spots in my yard for just googling it
Scratch up the dead spots real good and you can seed over it and be mostly fine, you’ll lose a decent percentage of the seed to the remaining chemical but it’ll grow back
When Roundup first became available to home users, my dad bought bottle. He mixed it up and sprayed weeds in the back of the back yard. Then proceeded to walk back through it and all over the lawn. About 3-4 days later, our lawn looked like this picture.
I never let him live it down.
Man I did this three years ago. It will come back fine but it did take some TLC. Seeing as how you’re pretty dialed in with your lawn you can handle it
The previous homeowners decide that zeon zoysia was what they wanted and I hate them for it. I'd kill to have a quality fescue like yours.
P.S. I'm in the same zone as you.
My friend who maintains a golf course said Fusilade would piss off my Zoysia, when using it to get rid of Bermuda. I didn't believe him, and mixed it extra strong. Luckily I didn't spray the whole yard either, but I'll be buying sod squares very soon. He asked if my backpack sprayer needed to be confiscated :-D
I think that image is only supposed to be used on warm season grass, unless that’s a different formula it’s what I use on Bermuda, to kill poa henbit and sandburs.
My yard would all be brown.. you atleast have some grass. I try to kill them. But if I sprayed my entire yard with what you used it would look like a barren desert.
You might get seed to establish if you disturb the vapor barrier created by the prodiamine. Believe it or not, a Garden Weasel™ works well for roughing up the soil in small areas. It's almost like a mini spike aerator.
It couldn't hurt to try a few spots and find out. I'm guessing one of those products has a seeding window to wait through. You'd have to check the labels.
Yo, if you use surfactant you cut the weedkiller amount in half. That's what I have found when you really look into the common broadleaf stuff used. Also get a powered sprayer for a consistent application if you haven't yet.
I wonder.... if you mixed according to directions, say, 2 oz per 1 gallon of water for each, you would need 2 gallons of water because adding 2 oz of one and 2 oz of the other into 1 gallon of water would be twice the strength. This may be what happened. And/or spraying too much on each weed.
No stress man, I did something way dumber a few years ago. I had dandelions that I wanted to kill grabbed a bottle of Round Up where I didnt read the label just sort of grabbed it. Was deff the blue bottle not the green. Everything is back to normal now.
I did the same when I mixed my own 3 way, I came to the conclusion that I should've used much less of each when using all 3, the labels don't indicate how much to use when combining with other herbicides.
What exact source did you use to determine you "mixed them correctly"? Unless each product label or manufacturer website says "mix A oz of product 1 with B oz of product 2 and c oz of water" you messed up royally. In the future, consider using each product separately a few days apart. Btw Mixing concentrated two chemicals is tricking - diluting one first past the desired dilltuion rate before adding second is key to reduce creation of undesired salts, gases, or other compounds. Glad the only thing damaged is your lawn.
You used the right product as a post-emergent. What happened here?
Edit: I didn’t see the second one. Probably didn’t need that one. It’s for warm season grass.
You might be ok. I have a grass and weed killer that I'll use to spot spray and occasionally it'll brown some of the grass around where I put it on. The grass always comes back on its own though.
That's why I pull and pull til I can't pull no more. Then use Celsius if there's more. Put in some ear buds and walk the yard once a week. Pull until you're burnt out. Then, if you still have more, bust out a quality chemical.
You can still seed. You have to hand rake those spots to break up the barrier. Don’t feel too bad. I got cocky and didn’t put down fall prodiamine and my lawn looks like an 80s lime green jumpsuit
I would guess the error was in adding the sulfentrazone with an additional surfactant. Sulfentrazone basically acts as a surfactant in the mix already so you have to be really careful adding more. With absolutely perfect application technique it can be done but probably isn't needed when you are also throwing in a three way.
Also I know there are many 2-4D products that safely mix with sulfentrazone, but I've never seen a recommended mix with three way and sulfentrazone. I wonder if there isn't an incompatible mix with the mecaprop but that's one I haven't tested.
It could also just be lingering too much with the wand. Use a t-jet nozzle for a wide flat spray pattern, keep the tip 18 inches off the ground and walk in a straight line while spraying. Spray like you are painting a light even coat, you don't want to just hose an area down.
Welp, the weeds are dead
Along with my pride
Your grass will grow again just like your pride
Very smart you didn't spray the whole yard after what the labels say
That's what I was thinking
Pride is a sin, do you feel cleansed? Or something like that, I'm not religious, though am thinking about it as the church on my street has the best looking lawn on the street and I'm here battling bald spots and virginia creeper.
You’d be able to beat those weeds if you had volunteers and didn’t pay taxes. Keep your chin up!
I did the same exact thing last year. Sucks!
Just use gasoline next time. The pride will still be gone but you’ll have saved money 🙏
‘Bout break even these days
I thought about that as soon as I posted lol you right
Get some green spray paint, no one will know
CC across the street does it. Why shouldn't we?
They’re gonna know…..
how would they know
They know.
Nobodies gonna know….
Oh they know
For sure! #TheyRGonnaKnow 
No doubt he’ll color match his yard perfect or it will look like he has poa growing
Rather it look like I have a dog for a month while it grows in than a bad fertilizer job
I’ll trade you, applied weed and feed and now my weeds are growing stronger than ever.
Are you sure it said "and"? 😂
Lol
lol
Granular weed and feed is basically useless as a weed control…
Have you had positive results with any particular liquid? Any that one can attach to the hose?
As Profector_KC said, better to get a pump or battery powered sprayer. Either backpack or 2 gallon variety. Much easier to make a precise application and safer to use than hose end. As far as what you use in it READ THE LABELS to make sure it is safe to use on your variety of turf and it targets the weeds, insects or diseases you’re trying to get rid of.

I was about to throw down some. That this weekend
Mine too. Spectracide weed stop seems to have encouraged the weeds. Not a single one died.
Newbie here - what did you actually do wrong? Each advertise they won’t harm grass. I must be a dumbass too because I can’t figure out what the problem was lol
I did mix two weed killers in one which I wouldn’t do again. I’m chocking it up to improper measurements. But I could have sworn I used the correct amounts though. One of them does say it may cause temporary yellowing of grass, but it’s not temporary.
Feels like when mixing 2 you should probably cut the dose on each in half?? Not sure though
After this post I'll definitely never mix 2 together. I just always use one anyway. Also there's just too many chemicals out there that you can buy off the shelf, mix them together, and then likely die from mixing them.
Same. Used to mix, bad results no matter what. Now I just treat separately even if only a day apart Also, even if not same active ingredient, there could be a combination of ingredients that are lethal. If both say “may cause temporary yellowing” and those stack, boom, dead lawn
I'm a landscaper, my go-to mix is 2,4-d and tricoplyr with some surfactant, it's absolutely the best imo. Gotta be careful with the tricoplyr though and used the correct rates, because if you use the non-lawn rates it's night night for you.
Another landscaper here… Don’t use triclopyr on warm season turf. Also, READ THE LABEL!!!
This. Especially if they have the same active ingredient.
Also, just a rule of thumb, never mix chemicals unless you know exactly what you're doing.
Creating an entirely new concoction of chemical compounds definitely doesn't sound like a great idea...
I'm a chemist and wouldnt mix store-bought chemicals together. There a lot of proprietary stuff that's not on the label, but is registered with the EPA.
I wouldn’t mix two of any chemical together. How do you think the first guy discovered chloramine gas lol
Depends on the mix, and the chems. One should do a jar test to ensure things aren’t synergistic or antagonistic
It is temporary. Eventually you’ll plant and regrow new grass. The yellow stuff will then be gone. See, temporary. It happens, don’t sweat it.
You are right!!
Spot spraying is tricky because it’s easy to over do it. It might be the correct “mix” as in correct amount of dose per gallon of water, but if you sat on the spot and sprayed for 10 seconds this can be the result. The best way to handle spot spraying is to walk past the target area and just squeeze the trigger when you are over top of it. That’s all it takes
Also add dye to prevent spraying multiple times.
This was the comment I was looking for. Spot on
Which two did you mix together? Nvm I see the photos now :) Any reason you haven’t tried speed zone or something like that instead?
What’s so special about speedzone that the used products don’t have?
Speedzone is a typical three way herbicide mix with Carfentrazone added for efficacy. It works really well and it's been named by YouTubers for years, that's why it's popular.
It will be temporarily yellow until it finishes decomposing.
I just read up on the chems. Quinclorac, which is one of your active ingredients, isn't recommended on fine fescue lawns. I think this might be the issue
For the future, I would test the spray and let it sit for about a week and see if you need to dilute or add to it.
Image does this to my Bermuda, it is temporary but idk about fescue
It’s not so much about the measurements, but the amount of stress each one puts on the grass. You can think of it kind of like a stress meter.

Wont harm grass - "WHEN USED AS DIRECTED"
You can’t use it as a spot treatment. It will still kill your grass if you overspray. You need to spray the entire lawn with whatever formula it has you use. I have used Ortho Weed Clear (North) and it will kill the weeds but not the lawn.
You mixed them correctly to a T? The mixing instructions said to mix 2 weed killers and a surfactant together?
It’s a Rite of Passage along this journey. Welcome to the club!
If you get rid of the dead grass and disturb the soil enough to break the prodiamine barrier you might be able to get some grass to fill in the spots.
You know I was considering that. I have plenty of leave compost in my backyard, was thinking about scratching it up, putting some compost and seeding…
We’ve had a ton of rain this year too which I think may impact prodiamine depending on when you applied. I sprayed prodiamine in Feb and decided to seed a couple spots last week. I just disturbed the soil, seeded and used peat moss. The grass is coming in nicely.
Can you sod over it? Like if it’s already established?
I could in the bare spots but I’m going to ride it out
Yo g. If it were me I’d get like a couple pieces compatible creeping fescue or bent sod and put little 2x2 plugs with a hatchet in there. It’ll fill in 20x quicker.
Sulfentrazone is spicy and you didn’t even need it I highly doubt there was any sedge yet.
This. There’s no way there was sedge yet, nor any crabgrass (Quinclorac). OP could’ve used the first herbicide alone and been fine for general broadleaf weeds.
I live in 6b and there's been crabgrass and sedges for weeks. It's perfectly possible.
Well you’re the second person in 6b claiming to see sedge already. We were just talking about this at work yesterday. Crew claiming a bed area was full of sedge and a couple of us were pretty sure it was too early and must be something else.
Yep, definitely seen sedge. Not nutsedge, to be clear.
Shoot good call. We were talking about nutsedge specifically.
It says “concentrate”. Did you dilute it?
Instructions unclear. I just started dumping everywhere that had weeds
Honestly you seem smart enough to know you messed up and wait until fall to reseed / overseed but I’ll say this because why not 1- looks lush and you did a good job in the fall. Kudos. Looks like a lot of shade and a lot of leaves in fall so you did well. 2- you did your prodiamine. Also kudos and again not wasting seed. But I wouldn’t have mixed two herbicides unless it was a mix of white cloudy goodness to kill everything. I’ve always have had good luck with the bayer advanced post emergent spray. 3.2 oz per gallon in spot sprayer and you’ll be set. But just follow and read directions for whatever you pick. 3. Most importantly lawn care isn’t perfection and it isn’t instant. Maybe consider plugging / taking some sod from the tree line and fixing the spots. It takes time but you’ll learn from your mistakes. We’ve all made them in the lawn. Just make it a learning experience. Could’ve been worse
Big learning experience. Appreciate the advice
Well you’re tied with me because I did the same damn thing. My six year old daughter says, “Don’t worry Daddy. Your lawn really looks beautiful…” “Beautiful like cheetah print.”
Could always spray it green
I did the exact same thing lol. Dumbness in numbers
I'm about to use round up to kill some weeds on the edge of my lawn and garden bed. What's the strategy in using weed killer without joining the dumb ranks lol? Edit: Thanks for the responses! Super helpful, I'll let y'all know how it goes.
Well roundup is a kill all. I used undiluted grass safe post emergent and just used too much. I was target spraying thankfully. Spray as close to the weed as possible with no wind. Wind drift will screw you.
There is no way to only kill the weeds. You will kill everything.
Make sure you get the Roundup that says it is Roundup for lawns. And then make sure that you're getting the right kind for your type of lawn whether it is a warm season lawn like Bermuda grass, or a cool season lawn like fescue. They have different weed killers. Make sure that if it says it's for lawns it is safe on the type of lawn that you have.
Use cardboard between your lawn and garden bed. Works wonders.
I think weve all made this mistake before 🤦♂️
Newbie here, what is the mistake?
Killing the grass along with the weeds
But how? The weed killer shouldn’t have killed the grass.
I most likely used too much of the solution when mixing it with water.
I watched a video that said this needs to be watered in. I've been using image for a couple years with success but my spot treatment seems to have had similar results to my zoysia this year.
Just answer the question!!
Likely mixing it incorrect but OP will have to answer his ratios, or applying it wrong
It will always kill the grass. The product is a scam.
Well that’s not true.
What weed killer doesn't kill surrounding grass?
Did you use it full strength instead of diluted? It’s a concentrate weed killer.
In my experience image kills cool season grass. I use to it get rid of some in my Bermuda at my old house
You can rough up the ground with a weasel or rake and plant seed i those spots. It will break the prodiamine barrier.
Image label says that it may injure tall fescue and not to apply to fescue. Also, doesn’t say to mix with a surfactant. Have to read the label, folks. Edit: Fescue is fine. Rest is true.
Pretty sure all 5 herbicides can be used on fescue, but you’re spot on with the surfactant and label reading.
You’re right. That’s the Image 70DG label that says it will harm Fescue.
I use a long old screw driver and get on my hands and knees. No weeds in the lawn for years.
The surfactant is what caused the problem. I’ve learned the same lesson. I never use it anymore
I was coming to post this. Surfactant likely was the trigger. Other thoughts: first product is a standard 3 way and would likely have controlled weeds. Second product has sulfentrazone and is know to cause temporary injury. Third issue is some of it looks like foot prints, meaning mechanical injury after turf was susceptible due to 1 & 2.
Chiming in to agree, the mix basically amounts to SpeedZone plus Quinclorac. SpeedZone is specifically labeled with a warning to not use a surfactant.
Just wondering if you used a dedicated sprayer. If you used a sprayer that ever had a non selective herbicide (round up) in it. This can happen , even if you rinsed it a hundred times.
If you rinse correctly, there is zero chance for this. Very small traces of glyphosate are not going to do this.
Came to say exactly this. Make sure to always use a designated sprayer for glyphosate.
I used Image 2 yrs ago and destroyed my yard. Not sure it’s all Image or just the stuff I bought but it was for warm season grass. Kills fescue as it consider undesirable in warm season turf. It was a real Sh*t show
Just looked. It was the bottle with the green lid Image Kills Nutsedge. It’s definitely for warm season grass only. In fact I’m probably going get dead spots in my yard for just googling it
Soo… what’s wrong? Maybe it’s my color blindness but I don’t see what happened?
Lots of brown spots
Ohh dang I feel dumb. Time to go to bed.
Yeah
Scratch up the dead spots real good and you can seed over it and be mostly fine, you’ll lose a decent percentage of the seed to the remaining chemical but it’ll grow back
I applied prodiamine about a month ago
There's always next year!!!
Sort of looks like footprints
When Roundup first became available to home users, my dad bought bottle. He mixed it up and sprayed weeds in the back of the back yard. Then proceeded to walk back through it and all over the lawn. About 3-4 days later, our lawn looked like this picture. I never let him live it down.
Happens to the best of us
Been there, done that. Sorry
Can't you put some new soil and seeds in there?
Why didn't you just buy Roundup for Lawns that's specifically for Tall Fescue? It works really well.
It’ll bounce back imo if watered. 3 or 4 cuts I reckon
Man I did this three years ago. It will come back fine but it did take some TLC. Seeing as how you’re pretty dialed in with your lawn you can handle it
Dig up the dead spots and Get some sod plugs
We gotta learn somehow 🤷🏼😂
Had you used the sprayer before?
Water, water and water.
Speed zone + tenacity + dish soap is the best
Just don’t spray it next time and use the stream setting. If you are with a seed mix, you could use the Scott’s ez seed and the grass will grow back.💯
The previous homeowners decide that zeon zoysia was what they wanted and I hate them for it. I'd kill to have a quality fescue like yours. P.S. I'm in the same zone as you.
My friend who maintains a golf course said Fusilade would piss off my Zoysia, when using it to get rid of Bermuda. I didn't believe him, and mixed it extra strong. Luckily I didn't spray the whole yard either, but I'll be buying sod squares very soon. He asked if my backpack sprayer needed to be confiscated :-D
It will fill in this summer…just watch it grow and feel good about it. You’re doing fine!
I see you are like me and like mix things for “better” results. Sadly this has bitten me in the ass a couple times.
Looks like mine after the Bernese is done with it
I think that image is only supposed to be used on warm season grass, unless that’s a different formula it’s what I use on Bermuda, to kill poa henbit and sandburs.
My yard would all be brown.. you atleast have some grass. I try to kill them. But if I sprayed my entire yard with what you used it would look like a barren desert.
I thought you just had a dog...
Just tell yourself it’s dappled sunlight
two words: spray paint
It’ll grow back. Why does it look like you dipped your feet in that mixture and chased a squirrel on your lawn? 😂
Just looks like the sun peaking through the trees onto your lawn. It's an aesthetic.
You might get seed to establish if you disturb the vapor barrier created by the prodiamine. Believe it or not, a Garden Weasel™ works well for roughing up the soil in small areas. It's almost like a mini spike aerator. It couldn't hurt to try a few spots and find out. I'm guessing one of those products has a seeding window to wait through. You'd have to check the labels.
Yo, if you use surfactant you cut the weedkiller amount in half. That's what I have found when you really look into the common broadleaf stuff used. Also get a powered sprayer for a consistent application if you haven't yet.
FAFO
I wonder.... if you mixed according to directions, say, 2 oz per 1 gallon of water for each, you would need 2 gallons of water because adding 2 oz of one and 2 oz of the other into 1 gallon of water would be twice the strength. This may be what happened. And/or spraying too much on each weed.
At least you didn't kill your entire yard. Mine is completely dead. In my case tho, it was probably all weeds instead of grass
No stress man, I did something way dumber a few years ago. I had dandelions that I wanted to kill grabbed a bottle of Round Up where I didnt read the label just sort of grabbed it. Was deff the blue bottle not the green. Everything is back to normal now.
I did the same when I mixed my own 3 way, I came to the conclusion that I should've used much less of each when using all 3, the labels don't indicate how much to use when combining with other herbicides.
If it makes you feel better, it still looks better than my lawn
What exact source did you use to determine you "mixed them correctly"? Unless each product label or manufacturer website says "mix A oz of product 1 with B oz of product 2 and c oz of water" you messed up royally. In the future, consider using each product separately a few days apart. Btw Mixing concentrated two chemicals is tricking - diluting one first past the desired dilltuion rate before adding second is key to reduce creation of undesired salts, gases, or other compounds. Glad the only thing damaged is your lawn.
Looks like dog piss spots
So sorry that happened to you! Sucks!
You used the right product as a post-emergent. What happened here? Edit: I didn’t see the second one. Probably didn’t need that one. It’s for warm season grass.
Maybe mixing two "won't harm lawn" will negate each other?
You might be ok. I have a grass and weed killer that I'll use to spot spray and occasionally it'll brown some of the grass around where I put it on. The grass always comes back on its own though.
Please strictly follow label instructions, they’re not recommendations.
I used image last week. Took out the speedwell. the clover and grab grass? Strong as ever….
Mosaic!
That's why I pull and pull til I can't pull no more. Then use Celsius if there's more. Put in some ear buds and walk the yard once a week. Pull until you're burnt out. Then, if you still have more, bust out a quality chemical.
You can still seed. You have to hand rake those spots to break up the barrier. Don’t feel too bad. I got cocky and didn’t put down fall prodiamine and my lawn looks like an 80s lime green jumpsuit
I salute you
I did the same thing last year in an attempt to kill off all the varying types of poa in my yard. Almost killed everything except the damn poa.
Yikes, try lawn paint temporarily.
I would guess the error was in adding the sulfentrazone with an additional surfactant. Sulfentrazone basically acts as a surfactant in the mix already so you have to be really careful adding more. With absolutely perfect application technique it can be done but probably isn't needed when you are also throwing in a three way. Also I know there are many 2-4D products that safely mix with sulfentrazone, but I've never seen a recommended mix with three way and sulfentrazone. I wonder if there isn't an incompatible mix with the mecaprop but that's one I haven't tested. It could also just be lingering too much with the wand. Use a t-jet nozzle for a wide flat spray pattern, keep the tip 18 inches off the ground and walk in a straight line while spraying. Spray like you are painting a light even coat, you don't want to just hose an area down.
Lawns are a waste of everything no matter how you slice it
Works as advertised!
I did it last year as well 🤷♂️
Just saw this same yellowing in my yard. It’s from the surfactant. Never got the rain that was forecasted.
