-It is exceptionally effective and noticably faster than any 3 way or 4 way turfgrass herbicide that doesn't have either sulfentrazone or carefentrazone type ingredients.
I've used a 2,4-d 3 way in early spring and saw near zero damage to the weed and TZone killed it without appearing to slow down.
Ive sprayed common broad lead weeds in summer when they are not showing signs of active growth and the TZone had almost no effect. Added a soluable nitrogen (ammonium sulfate) and it killed many weeds that aren't actively growing and a common 3 way with nitrogen did nothing.
The big shock for me was I really tried to get rid of creeping charlie for 2 seasons and last season Tzone was applied twice in spring and a few days after 2nd app the lawn cut shorter, de thatch raked manually and top dressed the front lawn with 3 cubic yards of very good compost 1/4 inch average depth. The charlie DID NOT COME BACK. I tried really hard to bury it before... applied way to much 3 way my first year that the grass turned pee yellow and died. I hadn't discovered these forums yet. I went a little crazy hand pulling 15+ a day often over an hour with a gardening shovel until I could see zero Roots of rhizomes. Nothing worked and it was spreading to over 1/3 of my front lawn. Say 900 sq ft or charlie with 500 sq ft packed tightly with creeping charlie...
.So you can understand that to this day, it blows my mind how easy it All disappeared. Its 6-7 months later and no ground ivy is on my lawn. I saw a few tiny baby creeping charlie after scalping the back yard during a call renovation baby ground ivy is very vulnerable until t
The only mistake I had to make was you need to mix it well. Its a thick milk color and adding water won't mix it like a 3 way. I did a half hearted tank shake and I killed the grass from the bottom part of my tank where it was super concentrated. I did the same error with Tenacity which requires even more energy to mix.
I suggest a cordless drill with a long mixing bit.
Finally the main con is the price. I bought the largest jug because it's what was available and spent nearly $300. So I never keep it in the heat or cold extremes to add shelf life.
