I’ve been using tenacity for six months fighting for a lawn that’s been neglected for decades. I just bought an old 1950 bungalow and it’s on an acre of....weeds. It’s a battle but tenacity is the best. Using surfactant and lawn dye and a backpack sprayer (and nitrile gloves) has really helped. It’s taking time and I’ve been applying for just over six months. My yard is about 60% and I’m really pleased with how it’s progressing. Highly recommend
The best way to mix your Tenacity is a Empty water bottle . Use the syringe to pull the proper mix rate then put the product into a water bottle and fill with water half way . Now shake the product until all the product has broken down.. make sure your back pack sprayer is half full of water.. NOW pour the Tenacity ito the back pack sprayer and shake back and forth and then fill the backpack sprayer completely up to the desired fill rate. Tenacity is thick and can fall to the bottom of the tank there for you will not get a compleat strength of the product . By pre mixing u are guaranteed to get better results .
fret master I used a gatorade bottle marked with what was used in it. Hahaha I thought I was the only one who mixed it up like this. Started it with blindside so that I knew it really was mixed because it would sink to the bottom and visually told me what to do next.
Thank you for the "2 - 3 weeks before reapplying" comment. There are a lot of videos on Tenacity, but those don't talk about when to reapply. I appreciate you for getting straight to the point and showing your application technique.
I ditto. Noone is mentioning when you apply the 2nd time. I did find an article from a university that mentions you can apply after 28 days and saw no damage to grass seeds. I've also called them too which they were helpful.
Prior to filling your 4 gallon back pack sprayer, set it empty on the opened tailgate of your truck, straps facing you. Then when mixed and filled, just back up to it and put it on. Beats picking it up loaded off the ground. Water is 8 pounds per gallon, you know.
Just found this video last week. Put in an order for everything I need. Applying tomorrow morning. Will followup with my results. Finally going to take my lawn back from weeds
Nothing and no one talks about how to work it as a Pre-Emergent, thank you for this. Yard is filled back up with dorment Poa Annua crap, but will try irrigating tenacity in this Fall.
Trying Tenacity for the first time today. Using it on clover and nutsedge. We got 1.2" of rain in the past two days and nice cool weather for the next few days.
Fun note about ppe…. Most insecticides and herbicides* recommend eight mil gloves or thicker and most gloves sold as disposable are two mil maybe four mil if you’re lucky…. I hate that it’s so hard to follow directions for ppe and get the right stuff
Pronouncing chemical names is relatively easy. Figuring out what the heck the chemical names mean is the hard part. Hint: Maybe ask your customer service people or salespersons to pronounce the chemical name for you and then write it down in your own phonetics so you can remember it. Thanks for the great video on Tenacity!
Good info. I was in the same situation. I wanted to overseed but had some weeds hanging around. I applied tenacity 2 weeks before overseeding and then an 2nd app 2 weeks later with my seed.
In the future, if you are applying Tenacity as a pre-emergent herbicide, be sure to do any steps that will disturb the soil such as aerating before you apply the herbicide. This way, you are not interrupting your soil barrier.
Fantastic video, Paul! Thank you for your clear instructions. If I may note that some watched this video replying in the comments don’t seem to have an understanding of basic pesticide terminology. I’m no chemist, and I’m not saying this to sound like a know-it-all scumbag, but researching herbicide safety, application techniques, and functions such as pre-emergence and post-emergence before attempting to applying chems may save you headache and potential problems in the future Seth
I had a nimblewill problem and Tenacity wrecked it. Along with the other invasive grasses. Now I got my seed down hoping for some normal weather. It’s either a heat wave or pouring rain.
I bought the stuff, applied it, waited a month, only about 5% of the weeds turned white. I applied a second spraying; a little bit better results. Then applied a third and fourth application, it finally turned some weeds white, and some of them died. I guess it is worth a try.
We are sorry that you have not seen the results you expected from using Tenacity. Keep in mind that this product does not work on all weeds you may have in your yard. We are happy to trouble shoot with you and find a treatment plan to meet your needs. Please call us at 866-581-7378 for assistance.
Wonderful video. Okay any thoughts on how us new bies can get a beautiful lawn. Your video is most practical. I love it for not getting all lawn techie on us. Thanks for all you share.
I have a 10,000 sq ft yard and will use Tenacity as a post-emergent. I have a mix of clover and nutsedge infesting my lawn, but only have a 2 gallon sprayer. How many gallons should i expect to use?
According to the Tenacity product label you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallons of water for spot treatments applied at a rate of 1 gallon per 1,000 sq ft. Once absorbed, Tenacity quickly translocates throughout the plant. Weed growth is suppressed soon after application, as photosynthesis is disrupted. Death of the plant usually occurs within two to three weeks. www.domyown.com/msds/Tenacity_Label.pdf ... Tenacity product label www.domyown.com/nonionic-surfactant-for-herbicides-p-1771.html ... Pro Recommended Surfactant
Applying Tenacity can take 2-3 applications for listed weed applications and the use of a pre-emergent in your area to prevent crabgrass from germination is also suggested. When treating for clover, it can take multiple applications and takes time to be effective/show results. Are you noticing any discoloration of the weeds?
@@domyown after two months of waiting on Tenacity to do something and three applications, I used Image on the clover and it is starting to show results. Early Spring I used Ferti lome weed and feed as suggested on the Domyown site and this did nothing to kill the clover. Clover thrived after using it. I'm going back to Scotts products.
I so wish I had listened to a few extra minutes of your video cause that's when you mentioned the grasses NOT to apply it to. I pretty much killed most of my Zoysia which I had been struggling a long time to grow. Oh well. I guess it's time to plant ornamental peanut. Thank you for an excellent video.
Liquid tenacity is post emergent on the weeds. Chemical structure is pre emergent once it is no longer liquid aka in the soil. No one would just spray the soil. You would use a dry structure killer with a spreader and on other hand it would not stick on weeds but if it could it would be post emergent as well
Tenacity can be sprayed on bare ground/soil as a pre-emergent for labeled weeds at the time of seeding of tolerant grass types. It is the only pre-emergent we are aware of that can be used at the time of seeding.
Can you make a video or someone in the comments make a pinned reply showing a schedule of how to do everything. Like... 1st You use Tenacity to kill weeds. 2nd you cut your lawn, 3rd you aeraid your yard, then dethatch it. 4th you then overseed the lawn. Are these the correct order of it all?
I think that would be a great video to do, especially for the customers that are not familiar with the process of applying a pre-emergent. We have a video like this in the works, look out for it soon! Although, it seems you may already be on the right track. When used a post-emergent, you can apply Tenacity anytime before seeding, but keep in mind that it may take a couple weeks to kill the target weeds, so you would want to wait for those plants to die before aerating and reseeding.
I have a broad leaf zoysia, not sure what species it is. Purchased my house 2 years ago and started with 1 patch of about 30sqft in a 30k lawn. I’ve been using tenacity and it isn’t killing my zoysia. Been plugging it into dead areas and I’m about 30% zoysia now
Paul, I am planning to do some over-seeding my whole lawn in the fall. My questions are : I have some poa in my lawn. Do I blanket spray tenacity hoping that will kill the poa spots and seed my lawn or do I remove those spots with poa and seed heavily? I want to use tenacity as a pre-emerge but I do have those poa spot already there. I will use a surfactant as well. Do I water tenacity in? If I am using RgS, humic 12 and air 8 can I still use tenacity or wait after my tenacity application? Last question is do I need to re-apply tenacity 2 weeks later? What do u suggest? Thank in advance. Thank you for putting out great content. I follow your channel.
Thanks for watching and for your comments! Keep in mind that Tenacity is not going to kill existing poa annua in your lawn. Tenacity will only suppress new poa when applied as a pre-emergent. If you are going to overseed in the fall, then using Tenacity is really the only option, so it’s certainly better than nothing. You didn’t mention what kind of turfgrass you have, but if you have a cool season lawn, then you really would just use a non-selective like RoundUp or Avenger to spot treat any poa that is left (pretty unlikely in summer since it is not heat tolerant) and then reseed as needed. You can apply Tenacity anytime before or at the same time as seeding turfgrasses that are listed as tolerant on the product label (mostly cool-season grasses). You will use a surfactant with Tenacity when applying it as a post-emergent herbicide (but remember, it won’t kill existing poa annua). You generally will not spray Tenacity as a broadcast when using it as a post-emergent since it can cause whitening on your desirable grasses. You can apply it as a broadcast spray when applying as a pre-emergent. You don’t need a surfactant for that application, but you do need to water in any pre-emergent herbicide. You don’t need to re-apply your pre-emergent; you would only reapply when using as a post-emergent for weeds listed on the product label (see the chart on page 3): www.domyown.com/msds/Specimen_label_SCP_1267A-L3_1010.pdf Your herbicide applications should not interfere with your fertilizers. Just be sure you are using a lawn starter or similar fertilizer with higher phosphorous when overseeding to help the new roots establish. We are also happy to assist you by phone at 866-581-7378 M-F 9a-5p ET.
I had a stump ground down and brought in soil. I applied tenacity, overseeded and put down milorganite. Then we had 3 inches of rain. Should I reapply tenacity?
We will need to know what weeds you are targeting to recommend other products for you. Please feel free to contact us at 866-581-7378 M-F 9a-5p for assistance!
Great video! I just got my tenacity and surfactant in and I’m using as a pre and post emergent. I plan on over seeding in the fall. How long after applying this mixture should I put down fertilizer? Thanks!
There should be no issues applying Tenacity around the same time as a fertilizer as long the label on the fertilizer does not state that it cannot be used with herbicides. Though be aware that for post and pre emergent applications you will be applying as 2 separate applications. As a broadcast for the pre-emergent application and spot treating weeds directly for post emergent application.
Unfortunately, we don’t have time to go over the entire label in every video, but yes, Tenacity is very popular for Bentgrass control. Paul does show a surfactant being added to his tank at 3:58 since you definitely want to use this for post-emergent applications with Tenacity.
Very easy to understand the way you say things here, thank you for sharing and helping us. I have a 1000 sqft lawn with KBG mostly but some PRG and Fescue and of course few weeds, I'll overseed some bare spots, I raked and aerated already 2 weeks ago but I raked again 3 days ago (removing some thatch and debris from rest of not successful overseeding (from late fall). Sunday no rain , Monday 58% chance (so I don't risk) and I'll apply fungicide and insecticide after the rain , Tuesday through next Thursday is dry then I'll apply Tenacity on Tuesday , so next Thursday I'll overseed with some Micronutrients and in 2 or 3 weeks I'll make a ligh spray of Tenacity again. How many ml do I need for my piece of lawn(1,000 sqft)? Thank you 🎶🎶
When you using Tenacity for post emergent control of weeds you would spot treat them directly using the rate of 1 tsp of Tenacity with 3 tsp of NonIonic Surfantant in 2 gallons of water per 1000 sqft. Be aware though that once you seed you will need to wait until that new seed is growing and mowed 2-3 times or allow 30 days to pass before you can reapply Tenacity again though.
Thanks for the great video and instruction. I used Tenacity last summer (2021) and was amazed at the results. I didn’t realize how much crabgrass I had until Tenacity killed it all and I had to reseed large section of my lawn. I didn’t put down a second application last year and am planning to re-apply soon (summer 2022) as I have some weed coming back and still dealing with Creeping Charlie . Two questions (1) can I apply Tenacity in or around mature trees (65 year old apple tree) and planting (forsythia, dogwoods, pine trees, etc) and (2) please confirm precautions about pets. The instruction say keep pet off for 2 hour until dry - but what if the we get rain after application, eg the next day - is it still safe or do we need to get the pets off until it drys again
We recommend keeping Tenacity applications out of the drip zone of trees. Pets should be kept off treated areas until they are completely dry which typically takes 2-4 hours. The product will not reactivate if it is to get wet after it has dried.
Tenacity can be applied to newly seeded turfgrasses listed on the product label but needs to be within 7 days of seeding if you plan to do so at the same time. Otherwise you would need to wait to apply until the newly seeded grass has germinated, is actively growing and has established a good root system, typically 30 days after seeing or after at least 2-3 mowing so you cannot apply to newly germinated grass it is could inhibit this growth.
The label states that's the rate for spot spraying. Broadcast application is 4-8 oz tenacity to at least 30 gallons of water per acre according to the chemical label instruction
1 teaspoon of Tenacity per 2 gallons of water. I put it down 5 days ago Crabgrass is turning white. Clover and Creeping Charlie ( ground ivy ) have no color change yet. Temps have been mid to upper 80's without rain.
My lawn is 2600sq.ft and it took me 5 gals. I only mixed 1 tsp. of Tenacity to 2 Gals of water. After 1 week almost weeds turned to white now. I will re-apply after 3 or 4 weeks.
Lol, im cracking up. I messed up my calculations and used about 7 oz for a little less than a 1/4 acre. Well i guess we will see what happens when you DOUBLE DOWN lol
I love your video it's very informative , I have two questions . Can I use this product on St. Augustine grass ? And I live in deep south east Louisiana that gets me to my next question , can I apply in temp. above 92 degrees ?
Tenacity Herbicide is only for use on St Augustine when used in sod farm and cannot be used on home lawns that have St Augustine. Tenacity can be applied when soil temperatures are around 55 degrees or higher. Do not apply when air temperature exceeds 85 degrees. Feel free to view the label for more information on Tenacity - www.domyown.com/msds/Tenacity_Herbicide_Label_2020.pdf
I have a newly seeded tall fescue lawn. It is 4 weeks post seeding. I used tenacity on the day I seeded. Part of the turf is doing well, while other parts is very spotty. I just mowed it this week for the first time. When can I spray tenacity again to control the weeds that are emerging?
Foliage of treated weeds will cease growth after Tenacity Herbicide application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application can be made after two to three weeks for improved postemergence weed control.
You should not mow within 2 days before or after an application of Tenacity Herbicide or any other herbicides. It would be best if clippings were bagged after the first mow and application of Tenacity Herbicide. Bagging will help with lawn health.
Can you spot spray tenacity for already active POA annua in winter of high of 60 degrees when pre emergent blanket spray was already done 1 day from 2weeks applied? Aware tenacity is only pre emergent suppression of POA Annua not post emergent. But will it reduce seed head from regrowth after low mow to not see unsightly seeds? Mow will be 2 days before tenacity app if ok to try slowing down seed regrowth. I have to use pre emergent again in fall to prevent POA from coming back the next yr. It’s now 2/18/23. I plan to spot reseed some areas this spring very soon. I know pre emergent must be put out late august or super early September to prevent way less POA germination. You only need a month to reseed spot areas in early spring if pre emergent was blanket sprayed Feb 6 2023? I spoke to Weedman who did the pre emergent spray but just making sure 28 days or more is good enough time span for reseed in some spots is enough time early spring. I don’t plan to do anymore aeration cause it probable erupted more dormant POA seeds that I never had in more areas plus so much rain this winter. I can’t reseed in any areas by fall with dithiopyr to help prevent POA next yr.
Tenacity Herbicide's label states it will only surpress the POA as a pre, will not work on it as a post. Generally, pre-emergents are applied for POA in the fall, you may need to apply a post emergent now depending on your soil temperatures. Keep in mind that soil temperatures are different than air. Depending on what turf you are seeding will depend on when you can reseed. You can either apply Tenacity at the time of seeding or around within 10 days of application. If you miss the window of opportunity, you must wait 2-4 weeks if reseeding with fine fescue, otherwise you must wait 6-8 weeks for any other grass seed.
@@domyown I just reread label. I have fine fesque. So I can wait 2-4 weeks to reseed some bare spots. But mind you, 2 weeks before I applied tenacity spot spray on yesterday 2/20/23. I did first pre emergent blanket entire yard spray on 2/6/23. So I can still get grass to grow in the few bare spots I have started from 2/20/23 from tenacity? The bare spots are near where poa exist but don’t expect to reseed after POA dies in heat. I am sure the POA MAY slow down ugly seed head but not kill POA. That’s all I can ask for now with germinated POA. I couldn’t do last yr fall dithiopyr to prevent this POA cause I reseeded entire front lawn from liquid burn.
Been about 5 days and my lawn has not changed at all. Also they don't give you the syringe anymore, I guess that made too much sense. I've sprayed some parts like 2-3 times too. Still no difference almost a week.
When using Tenacity, foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application may be required depending on what weeds you are treating.
Tenacity Herbicide does need to be mixed with water when it is applied. You can water the lawn after it has been applied, but it is not necessary due to the product being mixed with water when applying. Please let us know if you have any additional questions.
I plan to use this on 1000 sq feet. If using as post emergent do you do spot treatment on the weeds or spray the entire yard mixed with water? If that’s the case and you use 1 teaspoon/2 gallons of water/3 tsp of surfactant that is way too much to do spot treatment isn’t it? Also, I plan to dethatch/scarify and over seed with turf type tall fescue in the fall. How many days prior should I apply tenacity for this to act as a pre-emergent for the next spring (2022) or do I really need to apply at the fall time since summer is done? Please also indicate/correct me on the order of things to do. I have - Dethatch - Scarify - apply tenacity - wait or don’t wait for any any number of days - Overseed. Finally, is there a need to again put a pre-emergent fertilizer/crabgrass preventer or again apply tenacity the next spring?
Tenacity Herbicide can be applied as a broadcast application. According to the Tenacity product label, you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallons of water for spot treatments applied at a rate of 1 gallon per 1,000 sq ft. Pre-emergents are typically applied in the spring when ground temperatures are about 55 degrees. Doing so will help many weeds from germinating next season. Here's a copy of the Tenacity Herbicide label here... www.domyown.com/msds/Tenacity_Label.pdf And this is a pro-recommended surfactant! www.domyown.com/nonionic-surfactant-for-herbicides-p-1771.html We have a general lawn care schedule here for your reference. www.domyown.com/lawn-care-schedule-a-537.html We suggest contacting your local extension office for specific timing in your area as well. www.domyown.com/what-is-an-extension-office-a-683.html
Let me also add this: Tenacity is a systemic preemergence and postemergence herbicide for the selective contact and residual control of weeds in turfgrasses. When applied as a preemergent, weeds absorb Tenacity during emergence from the soil. Dry conditions following application may reduce the preemergence activity. If rainfall (0.15 inches) has not occurred within 10 days after a preemergence application, activate with 0.15 inches of irrigation. When used as a postemergent, susceptible weeds absorb Tenacity through foliar contact and soil absorption. Therefore, you should water in Tenacity when using it as preemergent herbicide but it does not need to be watered in when using it as a postemergent herbicide.
You can get your post and pre in one shot. Let it sit for 2 to 4 hours after application before irrigation and you will have your post emerge control. Then water it in with 1/4" to 1/2" and you will have pre emerge control
Keep in mind that pre-emergent and post-emergent applications of Tenacity usually require different timing. You also should not do a blanket/broadcast application with Tenacity unless you are renovating or overseeding the yard so that you don’t get whitening on your desirable turfgrass.
Hi, I used Tenacity last Fall for the first time and had good success, especially with the Goosegrass problem I had. I plan to use it as a pre emergent this spring when the ground temps here in Pennsylvania hit 55 degrees over the course of a few days.. My question is, do I need to apply Tenacity without a surfactant, that way it gets watered into the soil easier? And should I follow up with a second application a few weeks later? Thanks
If you are apply Tenacity as a pre-emergent, then you would not need to add a surfactant, but you could to help minimize drift, if needed. Keep in mind that Tenacity is usually just used as a pre-emergent when overseeding since it’s one of very few products on the market that can be used at that time. You would not need to reapply if you have done a full rate application. In warmer areas, especially, you will usually make two applications of a pre-emergent at half the rate about 6-8 weeks apart. Feel free to call us at 866-581-7378 to discuss other options for your lawn.
I was waiting for this sort of information on Tenacity, thank you for this great video. Question, I applied Tenacity last Saturday as I'm planning to overseed soon, but it started raining 4-5 hrs after applying and been raining for past 2 days here in NJ, was my application wasted, do I have to reapply?
Great question! Tenacity is going to be rain fast 4 hours after it has been applied or after it has dried. That being said, a re-application may be needed two to three weeks to effectively control weeds.
If you are using Tenacity as a post emergent it is recommended to apply it with a non ionic surfactant, to help it stick better and increase effectiveness.
Great video quick question i made a mistake and put T on newly germinated grass because i forgot to put on during overseeding now it looks to be turning yellow do you think it will recover
Yes, the whitening of the target weeds and sometimes the turfgrass is normal per the manufacturer. Tenacity Herbicide is labeled to be used on Kentucky Bluegrass, Centipedegrass, Buffalograss, Tall Fescue, Perennial Ryegrass, & Fine Fescue. It is not labeled for Bermudagrass or Centipede lawns and can cause turf injury. The whitening you see is the active ingredient working its way into the weeds/grass which causes the loss of chlorophyll followed by the weeds dying off within 1-3 weeks..If using on cool season turf, you can reseed those damaged areas if needed.
Turtles are considered an "exotic" animal and herbicides such as Tenacity have not been tested around turtles so we cannot confirm safety. We highly recommend you contact your vet for the best recommendations of products that can be used safely around your turtles.
Yes, you can apply fungicides and herbicides at or around the same time as long as you are using the correct rates and observing any other label restrictions for both products.
Tenacity Herbicide will work both as a pre-emergent & a post-emergent. So depending on when you apply it will either prevent weeds or control those that have emerged. Below is our lawn care calendar to assist you on when to apply. You may also consider reaching out to your local extension office for assistance on the best time to apply in your area www.domyown.com/lawn-care-schedule-a-537.html npic.orst.edu/pest/countyext.htm
Tenacity Herbicide as a post can only be used to spot treat, and must be used with a surfactant such as Hi-Yield Spreader Sticker Non-Ionic Surfactant. www.domyown.com/hiyield-spreader-sticker-p-1898.html We also have a kit that includes both the surfactant & a dye to know what areas have been treated. Otherwise, if you are using it as pre-emergent you can use it as a broadcast spray.
Thank you for addressing second applications. Question...i put tenacity and seed about 25 days ago and did my 1st mow yesterday. I need to reseed the areas that are sparse. When can I reapply tenacity and will that mess up my existing growth? Thank you in advance
Per the Tenacity product label: Apply at grass seeding or close to seeding for best performance. Avoid spraying Tenacity on newly germinated turfgrass. Wait until the newly germinated turf has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application of Tenacity.
@@domyown I just did my first mowing 4 days ago and it looks like i did nothing. I'm also 30 days as well. Once the rain stops and the grass dried I'm gonna do a spray.
Your website has conflicting info. Along the same page it says not recommended for at Augustine. Then later it says ok for at Augustine. Then your video says ok for at Augustine My question is.... Is it safe for st Agustine grass?
We apologize for any confusion. As stated on the product label, Tenacity may be used in St Augustine (grown for sod only). Please be sure to review the product label for complete application instructions. www.domyown.com/msds/Tenacity_Herbicide_Label_2020.pdf
My wife hates all chemicals on the yard. I keep telling her I can stop and she'll have the most organic weedy yard in Houston but I don't think she'll win the "Yard of the Month" for our neighborhood.
I trialed Tenacity on an open lot area before putting it on my lawn bc I'm scared of messing up and destroying my entire lawn. So...I could not see the dye on the grass even when I doubled the dye! And I did see one person who also said they didn't even see it. Can you please give me any ideas of how I can improve being able to know where I've sprayed to avoid overspraying? Thanks!
You may need to add more of a blue dye if you have a deep green grass or when spot treating certain weeds. The only other additive dye that is sometimes used is green, and that would not be any easier to see.
Hi i follow your directions to apply this tenacity and right now i see a whitening on all the weed in my lawn. my question is do we need to take out the weed by hand after whitening or just leave it like that until die ? thank you
Tenacity kills plants by inhibiting the production of chlorophyll, so this whitening is normal and is the first sign the product is working. We recommend that you allow at least 10-14 days before pulling treated weeds so that they have time to die completely before you remove any plant tissue.
Thanks for the video! I just seeded my yard 2 days ago from scratch and completely missed this step I do see some weeds coming out due to the irrigation I have been doing..Can I still apply tenacity now?
If you used a turf seed that is listed as tolerant on the Tenacity label, then usually you can still apply within a few days of seeding since the seed will not have germinated yet. Once the grass has started to come up, then you would need to wait until it’s well established before you apply any herbicides.
Great video. You mentioned you were over seeding but before that you would apply again in 2-3 weeks after the first application. At what point after all of that will you over seed? Will you apply tenacity again at that point as a pre emergent? Thanks!
When treating with Tenacity as a post emergent you may need to do a follow up application at the 2-3 week mark to gain complete control over the targeted existing weeds. Most post emergent applications are done as spot treatments in the lawn. Typically you don't want to apply too much Tenacity too close to together to avoid causing the turf to whiten more than necessary. Once the weeds have died from the post emergent application and been raked out to expose bare dirt in preparation for the seed, you can apply the Tenacity as a pre emergent. You normally want to give about 2 weeks between the post application and when you apply as a pre emergent, then you can seed as soon as the following day.
Tenacity is labled for post emergent control of ground ivy. Tenacity is a selective herbicide that can be used to treat turf types found on the label, it can also be used to spot treat.
It would not be recommended to tank mix Q4 with other post emergent herbicides like Tenacity which require the addition of a surfactant for the most effectiveness. Q4 already contains a slight amount and does not require an additional one. You could use together only when applying Tenacity as a pre-emergent broadcast application to prevent weeds before they germinate and need to also treat actively growing weeds listed on the Q4 label.
I used the Scotts starter fertilizer with tenacity in it when I seeded(renovation) on labor day. I still have some weak spots and bare spots in the lawn. I also have crabgrass popping up like crazy. Can I apply this tenacity to my new grass and go ahead and reseed my bare spots or will it hurt my young grass(fescue)
Can I use this if I’ve fertilized my yard in the last month? I have weeds in my back yard. I was going to use Escalade2 but a buddy told me about tenacity.
Fertilizer will not interfere with Tenacity or other herbicides. Which is best for your needs will depend on several factors such as your turfgrass type, the target weeds, how large of an area you are treating, and whether you are overseeding. Please feel free to call us at 866-581-7378 for assistance with your specific situation.
Tenacity is labeled for crabgrass and should kill it when applied according the label. However, do not apply Tenacity when air temperature exceeds 85 degrees. What most of our customers do is apply in a cooler part of the day and wait for it to dry. As long as it's had time to dry, it shouldn't cause turf burn. Keep in mind, Tenacity Herbicide may cause temporary whitening of turfgrass foliage as it's killing your weeds. Please note it is not labeled for many warm-season turf grasses, please read what grass it's labeled for here on Page 8 www.domyown.com/msds/Tenacity_Herbicide_Label_2020.pdf
Is tenacity an effective pre emergent against Poa Annua. I’m guessing the answer is no but am hopeful thinking. I plan to oversee my rescue next week and try to outcompete the Poa Annua.
Tenacity is not labeled to control Poa Annua/Annual Bluegrass, it only states that it could cause injury to it if sprayed with tenacity. Since it is not specifically designed to control Poa Annua, a better product choice would be Echelon 4SC. Echelon 4SC is labeled for pre-emergent control of poa annua only. According to the product label Poa annua is a winter annual. Applications of Echelon 4SC Herbicide should be made in August or September to established, non overseeded turf before Poa Annua germinates. Consult your local Cooperative Extension Service for more specific applications timings for your local area since August and September are approximate timings.
DoMyOwn Appreciate the info! As far as I know when you are over-seeding with Tall Fescue and combating Poa Annua the arsenal of weapons you have in the fall lare pretty much nothing! :)
Worked awesome for weeds, Thank you, My new seeds seem to be sprouting white instead of green though, Is there something that can be done or is it doom? Thank you for any help.
Be sure your new grass is watered correctly and that you do not put extra stress on it. You can also apply an iron supplement to help with greening, but otherwise the whitened grass will grow out and be mowed off.
Is tenacity the most cost effective option for someone with 2+ acres of grass (tall fescue, surrounded by pines)? Also trying to determine if Spring- pre emergent treatment will keep weeds from coming up through summer? Or how many times I should expect to treat? TIA for the help! Hoping to make a purchase soon
Tenacity can be used for Spring pre-emergent treatments, if used as directed on the product label. You could also consider Dimension 2EW www.domyown.com/dimension-2ew-herbicide-p-1494.html as your Spring pre-emergent, which provides excellent preventative control of a long list of weeds, and may be a bit more cost effective considering the amount of weeds included on the product label, and the amount of time the barrier is active in the soil. Your Spring pre-emergent will last longer if applied as a split application ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bRqWL_O9W30.html to get the widest and longest weed prevention range you can leading into summer.

We're going to try it on wild violets that have taken over a planting bed. We hand pulled the big clumps and want to prevent any seeds from germinating. We're expecting a lot of rain this week, so should we wait to do the application?
When are use tenacity according to the label directions my weeds and grass tend to grow through it or out of it. I may have to shorten the time between applications. Great video!
Thank you so much for all the info..questions does Scott kentucky bluegrass work with tenacity..and can I sprayed tenacity to kill all the weeds and wait till weeds die and then over seeds and then reapply tenacity again..
Tenacity Herbicide is safe for established Kentucky bluegrass applications. According to the Tenacity product label you can apply prior to seeding or post seeding of tolerant turfgrass species listed on the label, except fine fescue. If you are applying Tenacity after seeding, you should wait at least four weeks or two mowings, whichever is longer, before applying Tenacity.
Tenacity Herbicide does need to be mixed with water when it is applied. You can water the lawn after it has been applied, but it is not necessary due to the product being mixed with water when applying. Please let us know if you have any additional questions.
The best temperature range to apply most herbicides, including Tenacity, is between 65-85 degrees. You can mow 2 days prior to application and 2 days following application of Tenacity Herbicide.
