- Are you needing a crabgrass post-emergent herbicide for your cool season grass? Having a good post-emergent strategy for grassy weeds like crabgrass is important so your using the most effective herbicide for your grass type. Here I discuss a few post-emergent herbicides that are very affective for controlling crabgrass in cool season grass.

Great videos !
Just a note! Tenacity mix rate for spot treatments is 1 teaspoon per 2 gallons of water with 3 teaspoons of an non ionic surfactant!
I’m outside of Chicago, and use Tenacity to control bent grass. It’s a problem in my neighborhood and took me a while to figure out that it was bent grass. But it helps keep it off my property.
I wish there was something that targets tall clumping fescue. I thought it was a type of crabgrass until Allen educated me last year in one of his videos. Instead I am forced to cut out chunks of it and hope that my KBG will fill it in over time. I just hate looking at bare spots in my lawn during the wait and then overseed in the fall or hit them early in the spring.
Tenacity - underrated as a crabgrass post emergent weed control. One of the highest single application products in crab post efficacy data
The clips are brilliant, thank you.
Great help thanks
With the heat my yard is majority crabgrass all of sudden. I had t had any my yard was beautiful. I’m going to need to purchase.
Can you use baby shampoo as a surfactant with tenacity
Thank you Allen. 👍👍
Thank you for an informative video!
I wish you would go into the time to leave Tenacity on the plants before watering in. As a "Pre" should be done in 24 hrs. As a "Post", they don't even say on their label. It's a big deal if treating 1 acre or more and can't water around 1/2 of it. How long should it be on "Post" emergent weeds before watering or rainfall?
Mr. Allyn, I was all set to go the Quinclorac 75DF route but now I'm wondering if there's any advantages or disadvantages with either the Quinclorac or Tenacity. Is it just "pounds on the ground" or other weeds that are covered or effectiveness? I appreciate your help and I'll see you on the lawn.
If you are cool season, Tenacity is all around best professional product to use. Easo to measure, easy to use. ONe pass spray and its all dead. Nutsedge, crabgrass, common weeds, done in one sprayer. See my comment above.
I may be hitting my crabgrass with a too-weak tenacity mix. The white leaves grow out and I'm back to green again. If I need to hit it twice (should I need to hit it twice?) when should I hit it again? 2 weeks, when I see the green appear or? Rules of thumb? Thanks lawn care nut!
Is it permissible to mix Tenacity and Quinclorac together in your spray tank as one mixed application or do these to herbicides require to be mixed and applied separately?
What do you think about a product like Quincept? It's a stronger 3-way with 24D, Quinclorac, and Dicamba and seems to work fairly well.
What about warm season grass types?
all of a sudden, once we got that heatwave, crabgrass exploded in my yard. i tried using Spectracide with Crabgrass Control, says it has quinclorac (only 2%). It didn't do anything at all and now i have HUGE patches. About to try Tenacity.
how did it work out?
It didnt kill anything in my weed patch
Allyn (or anyone who can answer) -- I'm going to use Quinclorac for the crabgrass because I bought a bottle last year but haven't used it yet. If I use it as a kicker along with Speedzone, should I use both at full rate? If I do both at full rate (x / gallon water), would it be OK to mix both product into the same '1' gallon of water, or should it be both at full rate, each into a gallon, yielding 2 gallons total?
I use Quinkill Max.
Can you mix quinclorac with tenacity. Also do you know of a product that works as both pre and post emergent that kills dichonrdra (pony's foot) or pennywort (dollarweed)?
I think he said the recipe for mixing Tenacity incorrectly. Always read your label first. If you use 1tsp of Tenacity you will be doubling the active ingredient. It should be 1/2tsp or 5ml per gallon, treating 1000sqft. 1oz will make 12 gallons of mix. Generics are available now at less than 50% of the name brand. Look for 40% Mesotrione. This stuff works. In Indiana(cool season mix) I mix it with MSMA for my (right of way) grasses and it that mix will get rid of nearly all annual weed grasses.
What do you mean by "tiller stage"?
google crabgrass tillers
Hi Allyn, if I had only a few crabgrasses that is not worth mixing Quinclorac... what if I just use a scissor and cut the crabgrass at the dirt level... will that kill the crabgrass?
I like Tenacity but saying Tenacitys low use rate is a benefit because less chemical goes on the lawn to kill the weeds (Implying safer) compared to other herbicide. Dont they realize that usually means stronger chemicals?
Only 10% needed because it's ten times as powerful....doesn't mean safer.
Or is highly concentrated 98% nitrogen a safer fertilizer for the lawn because it has a much lower use rate than 15%? Nope.
I like tenacity but that comment about its low use rate is bad science.
I have a different experience over the confusing concerns mentioned in the vid. Tenacity....not sure why we're getting deep into using it as a preemergent, never even knew you could. First, as far as any danger of not measuring a teaspoon right, they give you a syringe clearly marked to draw for one gallon. Period. NO math needed. Puzzling He doesn't mentioned that, just the concern. Second as far as being a beginner and applying it and doing damage? Simple: Spray only one pass as you walk by the weed or crabgrass. You do not have to and should not go back and forth or soak it. Spray as you walk on by, one coat. Compared to the other 45 dollar product? Considering that Tenacity can be used on every weed I have including Nutsedge, it is a real value. If you have used the box store products and got wimpy results, had to soak stuff for it to work, and had to reapply, Tenacity is much CHEAPER per gallon and its one time results. Simple. I'd respectfully suggest you take his advice and go elsewhere and watch a vid on mixing and applying Tenacity. It is not complex to mix or use, and the precision is made easy via supplied syringe. The only thing compared to box store wimpy stuff is you do have to add 3 things - tenacity, then surfactant, then they suggest a dye to mark where you sprayed since it is clear. Keep in mind that I'm using this on cool season lawn, not down south.
Tenacity doesnt kill any weeds that Ive found
