Great for removing tall fescue from bluegrass
This product is great for us that hate to have tall fescue patches mixed in with our bluegrass. On the internet the only way they say you can remove it is with Roundup. If you apply tenacity at normal strength to the Tall Fescue patches every 4 to 5 days then it will eventually kill the tall fescue and leave the bluegrass untouched. It takes 3 or 4 weeks to do it. You can not wait a week to reapply because the tall fescue can start to recover in that period of time.

Not a quick fix but did work
After 2 spot applications to control some invasive bent grass mid 2017 did notice some yellow/white strands down in the blue grass. Did not pay much attention later in the season but this year the results are visible. The large areas of bent grass are gone and only some of the fringe areas where I possibly did not get a full 2 applications down show any bent grass. No bare spots as the blue grass filled in nicely. Will do another 2 applications to see if there is any bent lurking in the turf, the yellow/white strands are hard to miss. Would recommend this product to anyone who has patches of bent scattered in their lawn but don't expect immediate results.

Great product when starting grass seed
Have not found anything else that works as well for pre and post emergent when trying to grow seed. DIY pest control service and shipping A+

Mixed results using Tenacity for Nimblewill control
Started treating my 30000 sq. ft. lawn in New Hampshire with tenacity and a surfactant last year putting down two applications about 2 weeks apart. First application was in late June and second in mid-July. Used concentration of 2 tsp per 4 gallons water. It took 7 full sprayers (28 gallons) to cover the entire yard. Some areas of the lawn were thick with nimblewill while other areas had sparse infestation of the weed. Tenacity started to show some whitening of the weed after about 5 days. I treated the entire yard and was surprised to see that I had nimblewill in areas I had not suspected. Results were mixed after all treatments were complete. Tenacity seemed to do the well in certain areas but definitely not 100% of the lawn. I used a 4 gallon backpack sprayer. Getting even coverage may have been my problem. Would suggest using a colorant which would help with even coverage. By the end of the season some areas of the lawn were bare dirt while other areas still had substantial nimblewill growth. Tenacity seemed to have no negative effect on grass in the lawn which is a northeast mix of blue, fescue and rye. Overseeded in the fall so bare spots began to fill in and by this spring lawn looked pretty good. Now, I am again seeing nimblewill in the heavily infested areas. In fact, some of the areas look worse than they did last year. Started treating the lawn again this year paying special attention to areas of thick nimblewill. Since this is the only product advertised for nimblewill control I am hoping that this years campaign will be more successful. Will come back and give an update.

Haven't found anything better for post emergence crabgrass killer in st augustine
First time user of Tenacity. Sprayed for post emergence crabgrass in st augustine lawn. Knocked it back pretty good but doesn't show yet an outright kill.(24 days since spraying) Will repeat spray again with a tank mix for post emergence broadleaf weed killer and/or nut grass killer.

weed killer
I used it on my st augustine lawn with a pumped up sprayer. 1 teaspoon in 2 gal of water. It calls for 2 applications and I appled the first and it is really doing a great job once I hit it a second time it should do the job. I'm very pleased and it is saving me a lawn service that would of charged me $100 per lick.
