    Damned Wild Violets!

    By S. on 05/26/2014

    Verified Purchase

    Nothing I have tried previously has worked on these things; Trimec, 2-4D, some others I can't spell :) A few days after application I was weary that this wouldn't work either, but after a week there was noticeable change. Looks like this did the trick!

    Tuflon Ester Instructions

    By Dr on 08/01/2016

    It's regrettable that the product label is a bit obscure regarding mixing small batches for spot treatment. Instead of describing how much product to add to "enough water to cover 1,000 sq feet." etc., how about a simple statement, e.g., X oz/tbls per gallon of water? Otherwise, time will tell if this really eradicates wild violets since a fair amount of time must elapse between treatments.

    Expert Response  Expert response:
    The instructions can be confusing at first. Please note that each sprayer can have a different output of product and each applicator moves at a different speed which means the manufacturer must keep this in mind when giving directions. With herbicides, water is just a carrier. The actual amount of water is not important. It is only important that you get the specified amount of product over the 1,000 sq ft area to avoid under or over treating. Calibrating your sprayer and application is very important. Please let us know if you have further questions. We are always happy to help!

    wild violets

    By Steve on 07/27/2016

    I have tried about everything to kill wild violets. Even Tru-Green say they are one the hardest weeds to kill because of root system. I sprayed a small portion of them to see if this would work, according to label it you should no spray if expecting rain within 24 hrs. Well it rained before than time, but was down about 20 hrs. I haven't sprayed them again, because every other day it rains. The good news is what I did spray is dead. I know this is only 8 oz. bottle and expensive, but I have used very little. I don't mind spending money for products that work.

    So far, so good to control Wild Violets

    By Owen on 09/28/2017

    My 1/3 acre suburban lot had been invaded by wild violets. Research showed these are hard to kill, with the best current herbicide being Triclopyr. The instructions made clear that 2 to 3 applications, 10 to 14 days apart, would be required to kill the wild violets. The mixing instructions on the bottle are targeted at large-scale applications (e.g., farming) while I needed only about 1 gallon per treatment to spot-spray the wild violets. Online information from DoMyOwnPestControl recommended 1 tablespoon per gallon of water. I also added 2 tablespoons of Hi-Yield Spreader Sticker (a non-ionic surfactant) to improve adhesion of the Triclopyr to the wild violet leaves. I did not see much change after the first application, which may explain some of the negative reviews here. However, a week after the second application many (not all) of the violets were starting to shrivel or had disappeared. I just applied the 3rd application and am hopeful Triclopyr will, in fact, help me control these pesky weeds. I suspect a 4th application may be needed here and there; 1/2 gallon may be sufficient for that. Impact on my grass has been minimal. Most of it showed no change. A few spots showed browning BUT it is possible those patches were not tall fescue, which is the variety Triclopyr does not harm.

    Waiting to see!!!

    By Frank on 07/05/2016

    I rated this a four star, but have used it once about 6 days ago to kill wild violets in my yard. So far, it has killed other weeds but I do not see any turn on the violets as of yet. Waiting to see as I was told by two garden centers that this is the best to kill the violets. Sure hope so.

    Works Well

    By Emily on 09/04/2020

    I bought this to combat morning glory in my yard. The day after spraying, the flowers on these weeds refused to open up for the sun as they normally would. A week after spraying, these vines have darkened in color and seem to be wilting. I also sprayed clovers and dandelions and these weeds have already started turning brown and wilting after only a week. I'm definitely pleased with these results.

    Seems to work well

    By Clint on 09/11/2020

    Good News: my bermuda grass invasion into my fescue lawn appears to be stunted. It also had a good effect on other unwanted grass types, while no stunting is visible on the fescue, or other plants. Bad News: I probably used at least 2X too much Triclopyr Ester because it was very difficult to decipher how much product to use per gallon of water. I've since purchased Hi-Yield Spreader Sticker to help the product stay on the plant longer and thus increase effectiveness. I'm planning to apply this product up to 4X/year to maximize suppression of bermuda grass.

    Good Results- Waiting for Spring

    By Bill on 11/20/2020

    After several years, wild violets and nimblewill weed were beginning to take over our yard. In some areas they were dense. Several years of applying Weed-B-Gone didn't have much effect. In late August this year, I used Hi-Yield Triclopyr Ester, (mixed with 2, 4 Amine Salt to treat the nimblewill) according to directions and sprayed my yard twice, waiting about 3 weeks between the first and second application. The numblewill began turning white and dying within a few days. The wild violets began curling and turning brown at the edges after a week or two, though some areas looked untouched (had new ones sprouted?). About a month after the second application (just Hi-Yield Triclopyr Ester this time), I noticed that the wild violets were gone in some areas and looked considerably diminished in other areas. Now, I'm waiting to see what the results are this spring.

    Best for tough weeds

    By Ken on 10/05/2018

    This product is the only one I have found that will kill wild violets in the lawn. It isn't completely effective, but nothing else does much of anything. It's pretty expensive, but this company had the best price.

    Hi-Yield Triclopyr Ester is not labeled to control crabgrass and would not be recommended.
