wild violets vs herbicide

I tested 5 herbicides on wild violets in my neighbors lawn with his OK, (Thank you). Week was dry; high temps about 85. In order of effectiveness at 48 hours, Quicksilver was most effective, Followed by T-Zone, Speedzone, Confront and Drive.
I will try to check the results again in about 10 days to better understand which products work best long-term.

Since Quicksilver is supposed to have mainly contact action--I am not sure if the roots or underground stems would be affected.

I'm about to tackle a bunch of it in a few lawns. We are already seeing cooler temps up here so I think I'll give t-zone a shot. Thanks for the tests, Riggle. I always read your posts.

After 14 days, T-Zone is still the most effective. Quicksilver is highly effective, but some regrowth of new leaves has occurred. Speedzone is in third place. Drive was fairly effective, followed by Surge and Confront.

Spurge was resistant to most products, but was killed by a combination of T-Zone and Speedzone, both full strength.

Drive was effective on a clump of crabgrass.

I have noticed that Q4 at least knocks the leaves down in the heat and if followed by t=zpne in the fall you will be golden. Q4 also kicks spurge's butt also. In the t-zone pic a few of the grass blades appear to have possible herb damage. I could be wrong as it is a pic and not in person. Have you noticed any turf damage from t-zone?

Not sure, but there may have been some slight turf injury from the T-Zone.

Drive had no visible affect on goosegrass.

Love your experiments. Thank you!

Not on the list, I have had very good results with Momentum FX2.

good test... I'll be blanket spraying two different yards full of violets and ground ivy followed by a two week later spot spray then another blanket spray two weeks later. Hopefully this cleans them up completely. They haven't been touched by a herbicide for years and are absolutely chocked full of weeds. Going to use t zone through my t3000.
