Syngenta 46256 Tenacity 8oz Herbicide, Clear

I recently purchased Syngenta Tenacity (8 oz), and I couldn’t be more impressed with its performance. This is a truly high-quality, professional-grade selective herbicide, and it shows in every aspect. Tenacity mixes easily, applies smoothly, and works exactly as intended when used with the proper surfactant and application rates. Within just a few days, I began to see targeted weeds—like crabgrass, clover, and other broadleaf and grassy varieties—turn white as the product interrupted their photosynthesis. It provided clean, consistent, and uniform control across the treated areas without damaging my desirable turf. What really stands out is how versatile and effective it is for both pre-emergent and post-emergent applications. The coverage is excellent, the results are reliable, and it’s noticeably more powerful and precise than anything you’d get from big-box store lawn treatments. Overall, the durability of the formulation, the predictable results, and the professional-level performance exceeded my expectations—especially for the price. I’d highly recommend Tenacity to any homeowner or lawn enthusiast looking to elevate their lawn-care program and achieve cleaner, healthier turf.

It's expensive and at first didn't appear to work. It turned my grass white and the weeds were still green. After 2 weeks the weeds were dead and after 3 weeks my grass was green again. Just have patients. It's better than pulling the weeds out with a screwdriver for sure

I applied during the middle of the summer on clover which was taking over my yard. it took a while to see any kind of results. majority of them died off but they all came back pretty quick. its now the end of September and the clovers just as bad as before.

Works as it should when applied correctly using the recommended application rates. Mixes easily and spray application ensures good distribution on the product.

This stuff is the best for lawn herbicide. I use it every year and every year I have people stop on the road and ask what company I use and I tell them I use tenacity and I quit using a company. you won’t be disappointed. start using it. I applied it a few times a year in the beginning and now I just have to use it once sometimes 2 times.

The product works well but the syringe did not fit into the surfactant bottle which was purchased separately. I used it to rid my lawn of a weed called brome which seems to be invading many lawns in my neighborhood. It took 2 weeks but it did the job. PS. If you use the dye with this product remember to wear gloves!!!

Didn’t work for me. It took me hours spraying this but either I completely did something wrong or it just doesn’t work. I researched and did my best to apply it correctly but I still see multiple Different kinds of weeds growing.

I live in upper midwest, went on vacation for 12 days and returned to see the crabgrass took off in some of my more bare spots of the lawn. My neighbor and coworker recommended this. It's pricey comparative to options at big box stores, but lets be honest, do any of those actually work on crabgrass?? I figured its still cheaper to buy this than pay a company to spray my yard! I applied as recommended with surfactant and dye about a month ago. You could tell in the first week they were no longer growing and within 2 weeks they began to turn brown (we haven't received much rain as of late). 3 weeks later I hit it all again as I don't want to get as much killed before winter as I can. This stuff really works, but can change some of your grass white for awhile depending on the grass you have in your yard. It will go away eventually though.
