Syngenta Tenacity Herbicide - Selective Broadleaf Weed & Grass Control - 8 fl oz Bottle

I didn't know such an effective and selective crabcrass killer existed until hearing about it in a YouTube video late in the season. It didn't just kill some crabgrass, it eradicated it from my property entirely, and had no effect on the grass itself.

I recently did a renovation on my lawn that is Kentucky Blue Grass, but was full of weeds and had Bermuda grass creeping in from the neighbors lawns. I used Tenacity to kill off the weeds and the Bermuda grass. In a few days the Bermuda and weeds started turning white letting me know that the product was working. In a few more days the weeds were dead as was the Bermuda. Tenacity worked as designed and I have used it on for other renovation projects because it doesn't harm my Kentucky Blue Grass.

Honestly, I figured alot less product for my usage area, then doubted myself and checked reviews. Word of caution, some customers do not know the abbreviations for baking spoon measurements. I used 3 tablespoons based on a review and my calculation was 3 teaspoons. My new grass went totally white, all weeds were killed and overseeding was successful. Two months later, the original grass is fine, and all is well.

Product worked well for me to eliminate nimblewill which was expanding year after year despite the yearly use of the common herbicides sold at big box stores. Product is very expensive and I suggest following mixing instructions and use sparingly

the product is very easy to use, especially with the measurement part attached to the bottle. mixing amount instructions were easy to understand. i find buying a concentrate saves you a lot of money and time compared to herbicides you buy in big box stores that may not work. this small bottle can yield you multiple gallons of herbicide solutions. be sure to purchase a surfactant to add to your mixtures so the tenacity can stick to the weeds.

I appreciated the effort to get it to me super quick. The Tenacity was at a excellent price and the container it comes in makes it easy to figure out how much I am using and how much water goes with the measured amount. I enjoy looking at my lawn with the understanding that the lawn will be much easier to maintain without stubborn weeds.

This product works great on many grass weeds plus... Read the label complete and follow directions to achieve the good results you want. This product will do what is says it will do well.

Arrived quickly and exactly as described. I used the least amount (1 TSP of this %26 1 TSP of dawn dish soap per 1 gallon of water) in a simple handheld garden sprayer. I covered both a large front yard and large back yard and still have half the bottle left. It has taken 4 weeks, but the unwanted weed grasses have begun to turn pure white. I am completely satisfied.

this product did work fairly well in killing quack grass and mature crabgrass but needed a second good application with a quality surfactant to allow the spray to stick to the plant and penetrate the waxy plant leaves. Without a surfactant such as Southern Ag or Petra ( for typical homeowners) the spray will not be very effective.

I followed the direction and spread to my lawn, it showed ZERO effects. The I doubled the amount and spread and spread to grass, it did not kill any weeds. Useless crap!!!
