Tenacity Herbicide Overview – Lawn Care Products | DoMyOwn.com

I think my back yard here has started to feel
the neglect and rebel against my taking care of the lawn at DMOHQ, because now it is just
full of weeds. Check it out! And because I’m looking at doing an overseeding
back here with in the first two weeks of September, I need to think long and hard about an herbicide
that’s not only going to give me post emergent control now, but give me a pre emergent barrier
right before I seed when fall rolls in. So what herbicide is good to do that? Let’s talk about Tenacity. So what’s up with Tenacity? What makes this so unique and different from
the other herbicides that are out there? So first of all, what’s really cool about
it is it’s a selective systemic herbicide that acts as both a pre and post emergent
for many broadleaf weeds for both cool and warm season grasses. And another really cool thing about it is
it can be applied on established or newly seeded turf. Grass types that you can apply Tenacity in
prior to seeding are going to include Kentucky Bluegrass, Perinnal Ryegrass, Tall Fescues
and Centipede grass. And a little side note, application at seeding
at fine fescues can be made if it’s less than 20% of the seed mixture. Another common question we get on this are
what grass types can you not use it in? So we don’t recommend that you use it in common
and Hybrid Bermuda Grasses, Zoysia Grass, Sea Shore Paspaylum…Paspalum, paspaulum,
that one! Or Kiku, kikua, ki, kikugrass, grass, kikugrass? I, I don’t know how to say that one either. When is Tenacity rainfast? It’s going to be rainfast within several hours
of the application under normal rainfall conditions. So if you’ve just got a monsoon rolling through,
I, I wouldn’t recommend it. Another popular question we get is can you
tank mix it with other herbicides? And the answer is yes! Ok, alright, for this section I couldn’t memorize
all of this so I had to turn to the trusty notebook write them all down so I didn’t forget
them. So, you can tank mix it with barricade, dicamba,
carfentrazone, triclopier, atrazine, cymazine, cyn, cym, cymazine? Why are these so hard to pronounce? Esmedachlor..bentazone and several three way
herbicides, so, this is, this is why I wasn’t a chemist. And the age old question that comes with a
lot of our herbicides is do you have to water Tenacity in? The simplest answer, yes and no. Let me explain. Remember, Tenacity is both a selective pre
emergent and post emergent for a lot of broadleaf weeds. When you apply it as a pre emergent, weeds
absorb Tenacity through the soil as they begin to emerge. Now if you have dry conditions during or after
the application that might reduce the pre emergent activity. Now if rainfall just hasn’t occured within
about ten days of the pre emergent application of Tenacity, you’re going to have to activate
it in the soil with about a quarter inch of irrigation. Now if you’re applying Tenacity as a Post
Emergent, systeable weeds are not only going to absorb it through foiliar contact but through
the soil as well. So conclusion, water it in if you’re using
Tenacity as a pre emergent but not if you’re using it as a post emergent. Alright so what is going to be the mix rate
for mine fescue in the back? Per the label it says I need to go one teaspoon
for every two gallons of water and three teaspoons of surfactant. So that means for my four gallon back pack
sprayer back here, I’m going to use two teaspoons of Tenacity with about six teaspoons of surfactant. So, let’s get to it! Also a quick note, one thing I really like
about Tenacity, when you buy it they send you this little syringe that marks off the
measurements for you. So one teaspoon right there for every two
gallons of water. So, that’s pretty cool. Don’t forget about your surfactant and please
wear your PPE. Go time! Done! Per the label I’ve got to wait two to three
weeks before I can make another application which I would like to do so that I can just
really knock the weeds out of here and get a protective barrier down before I overseed. So there’s Tenacity Herbicide! What did I leave out? Let me know, sound off in the comments below,

  1. 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.

  2. 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.

  3. 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.

  4. 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!

  5. 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?

  6. Absolutely excited about this product for a project next year. One product I'd like to see is one of the liquid micronutrient or humic products that domyown.com carries like Hydro-Hume T&O, TurfGrassPros Micros, or any other micro nutrient additives in conjunction with a proper soil test by a horticulturist from a local extension office. I'm curious about when to use or not use these products and if the extension office horticulturist tells you what you need to do of if you have to make that judgement.

  7. Great info, however I have a question… I de-thatched my lawn Monday, can I apply Tenacity tomorrow (Wed) to kill several patches of this weed (Rough Stalk Bluegrass), and aerate and seed on Friday? Thanks!

  8. So how long before I can resume regular watering? Like if I apply the chemical Wednesday and want to aerate and over seed Sunday when can I water?

  9. For the one teaspoon tenacity and three teaspoons surfactant per gallon of water. Does the backpack sprayer need to be calibrated or just go at it like you did?

  10. Thanks for the video. Have a question. Our lawn was over 50 percent bentgrass and before finding out about Tenacity we used Lesco Prosecutor to kill it off. Then dethatched the heavy layer of dead bentgrass. We were down to mostly bare soil and then slit seeded (Lesco seed) followed by starter fertilizer (all completed on 9/12). Since I don't want a return of the bentgrass or new weeds, can I still apply the tenacity as a pre-emergent? Or wait and use as a post-emergent as the seed will most likely start to germinate by the time I get the Tenacity ordered and applied?

  11. 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)

  12. I have some POA Trivialis in my lawn and have been dealing with it by just ripping it out by hand.  I had heard Tenacity helps some with POA T but also that is can harm Fine Fescue Lawns to.  Is this the case and didn't you put a Fescue grass down for the back yard?

  13. I'm planning to spray a blanket app of tenacity on my lawn and overseed this weekend. But there has been a delay in shipping of the TTTF seed I order. Can I still spray tenacity this weekend and then overseed next week?

  14. I used it over my Tall Fescue Lawn, I am getting alot of brown spotting on the tall fescue leaves, is this normal??, I used Brown out as a surfactant

  15. 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 .

  16. Paul, I am struggling to understand how much Tenacity to be using. I know its 1tsp per 2 gallons of water, but how many square feet should that be? I can make 2 gallons last 5K square feet or I can make it last 2K all depending on how high up I hold the wand of my backpack sprayer and how quickly I walk.

    Thanks in advance!

  17. Can I use this product to control Crabgrass in my tomato garden? Maybe not this year but next year before I transplant the plants

  18. I over applied the rate, half the water recommendation. Now lawn has white spots everywhere. What can I do? Will KBG come back from it? Did I just kill it all?

  19. 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

  20. How are you going to oversee When you are ready put down that product are you going to pull up the grass in oversea are you just gonna to throw it down Yep me understand hi it’s going to work because I have Burmuda grass

  21. https://goo.gl/YFL4PR Buy Tenacity Herbicide here! & don't forget a surfactant https://bit.ly/2LEMQZp + https://bit.ly/2y3O2g6 Sprayer used in this video

  22. Nice job castleberry. My wife loathes tenacity as a post emergent hahaha she don't like white tall fescue

  23. I have a question for you that nobody has asked yet. I just bought a bottle of Tenacity from your website. What is the maximum outside temperature recommended when applying the tenacity mixture? I have a lot of crabgrass that has emerged during the hot summer months and I would really like to put some down to maybe get rid of it before fall reseeding. The outside temperature has been about 80 to 90 degrees lately during the day.

  24. So, Mixing rate of 1 tsp. of Tenacity per gal. water, with 3 tsp of surfactant. But, how much sq. ft. Should that cover? Thanks, JohnG

  25. 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

  26. Thank you. You are very informative. I live in south Florida with st Augustine and Bermuda grass, what can i use instead of tenacity? Thank you again.

  27. 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.

  28. Sorry, one other question, Ive applied first app of Tenacity, can I also apply Scotts DiseaseEx for fungicide now? Thank you, JohnG

  29. 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.

  30. after 3 weeks, when the weed has turned completely white, do you pull it out of the ground or simply mow it to reseed good lawn grass?
