T-Zone, Violets Trouble

3 years ago

Violets were invading our 1.5 acre rural lawn (there's a back story that I'll skip). I tried using Hi-Yield Triclopyr Ester. It was effective but would have been prohibitively expensive. A wholesale lawn product supplier recommended T-Zone. It was wonderfully effective on the lawn weeds, but killed or severely damaged some nearby shrubs, even when I had been extremely careful not to spray their foliage (When working near shrubs, I used a tank sprayer, holding the wand down low, using very low pressure). I was stunned. And sick. I've possibly/probably lost 1 tree-form limelight hydrangea, 4 lo-grow sumacs, and a prairie aspen. Questions:


1. Does T-Zone absorb through the roots? Language on the label is too complicated for me.


2. What would be a good alternative? Something effective on violets (the average broadleaf killer like 2-4D is not), but relatively affordable and not so dangerous to shrubs. I used Weed-B- Gone or Weed-Free Zone plenty and never, ever had this kind of problem.


Thanks

    Did you try Weed-b-Gon Chickweed, Clover, and Oxalis Killer?

    No. Does it contain trylopyr? From what I understand (which isn't everything, for sure!) that's a necessary ingredient for killing violets.

    Could we go at this a different way than more herbicides ?


    Dont violets like really acid soil?

    have you had your soil tested?you may have created an environment that violets love and herbicides will not be a lasting solution if the underlying problems arent addressed

    yours is the 3 rd post in last 2 weeks about ”carefully” applied herbicid that drifted or transmigrated underground to adjacent plants causing serious .

    damage. In addition to getting your soil tested and asking your county extension service about safe lawn care, you might see if The Garden Professors have science and research based info on lawn care. they are a terrific group with excellent credibility. i think their main forum is on facebook but google should do the trick

    And may I ask, how perfect does your lawn need to be so you can enjoy it without resorting to industrial strength herbicides?

    Can you imagine ”acceptable imperfection” in a lawn?

    Hope you can find out about and try an IPM approach to lawn care

    Thanks, Marie. I appreciate this. Our lawn is way far from perfect. It’s out in the country in the middle of gravel roads in Felds and has every possible kind of weed imaginable, but the Violet’s were really really investing in the grass. Borax?. I’ll have to watch the YouTube.

    Wow. Just reread my most recent comment. Hopefully people can see past all the errors!

    1. Does T-Zone absorb through the roots? Language on the label is too complicated for me.

    Then, with all due respect. you shouldn't be using such products.

    I've used triclopyr for violets for years, right up to the roots of ornamental shrubs and trees, and never had translocation through roots. I would avoid doing so around members of the pea family, as they are especially sensitive to it. I have had a situation where I used the diluted ester, broadcast sprayed in large quantities, on a calm, cool night and it burn the foliage of some nearby ornamentals. I can only imagine something else in the Tzone, which is labeled for a whole bunch of weeds, caused the issue.

    Violets can be tough. There are a handful in my yard that I either have missed, or perhaps they are getting some resistance to growth regulator type herbicides. So I'm carefully painting them with a q-tip dipped in 10% glyphosate with a few ml of a strong surfactant (Brandt torpedo) to break down the waxy coating. This finishes the stragglers off. All the same my garden in the last 15 years has gone from having incredible dense growth of them to just a few. You really have to be careful with this weed. Nothing will invade a shady best faster and swamp out desirable woodland plants.

    Dchall you are right

    i deleted the dissemination of ?unproven info.

    ....I tried but apparently it did not work

    which perplexes me ....what happened to the three

    dots and edit function. Does it disappear on older posts
