Syngenta46256 Tenacity 8oz Herbicide, Clear

Best stuff ever. It controls most of the weeds in my lawn. I’m new to this stuff but this product is amazing.

I bought this because it claims to kill creeping Charlie. Most consumer herbicide claim they eradicate creeping Charlie, but don't. This does. It doesn't kill all of it, but almost all of it. I use it according to the directions. I added the dye, but I found that to be of no benefit. I could not see the blue dye on the lawn or weeds. So, on subsequent applications I no longer use the dye. I do use the surfactant.

It was delivered without a cap. This is frustrating

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.

Quality received as expected.

Check first to see if you have the weeds this will kill. Some I have still waiting. Was super easy to mix and apply with a sprayer I already had. Packing was fantastic giving clear measurement instructions. No guesswork. It goes a long way so you will have this for time again.

Overall Tenacity will somewhat control berumda grass however there are some drawbacks to consider. I have used this in an attempt to control berumda grass for two years and have had some sucess controling bermuda grass and it does turn the blades white indicating that the the plant is damaged. However the plant stays white for about 10-12 weeks making the treated areas extremely obvious for pretty much the entire growing season making the lawn look awful. I can work about four follow-up applications and frankly it does not seem to cripple the bermuda grass enough and in fact it is spreading.I have a tall fescue lawn in a "transition area" (zone 7b) and berumda grass is a gigantic problem. After two years of use I have decided to use a non-selective grass killer (Glyphosate) with repeated applications to kill all the grass and then re-seed. I would much rather see a few weeks of dead grass than brillant white for an entire season. I do understand that even glyphosate will not entirely kill bermuda grass but my experience is that it will put it in full retreat..Tenacity does control many other weeds and it may be worth using for those, however I cannot recommend for bermuda grass control.

This is amazing! I followed all the YouTube videos about how to use this. It killed vast sections of Bentgrass in my lawn, then I could remove it with a dethatching rake and reseed the lawn.
