HI-YIELD Triclopyr Ester is formulated as a low volatile ester. However, the combination of spray contact with impervious surfaces, such as roads and rocks, and increasing ambient air temperatures, may result in an increase in the volatility potential for this herbicide, increasing a risk for off-target injury to sensitive crops such as grapes and tomatoes.
Mixing Instructions
Add about one-half the required amount of clean water to the spray tank. Add HI-YIELD Triclopyr Ester and complete addition of water with agitation running. Mix thoroughly and continue moderate agitation while spraying. When this product is mixed with water it forms an emulsion, not a solution; separation may occur unless the spray mixture is agitated continuously.
Application Instructions
Broadcast Treatment of Ornamental Turf
Apply foliage sprays during warm weather, early spring through fall, when weeds are actively growing. Apply 1/2 to 1 quart of HI-YIELD Triclopyr Ester per acre in enough water to control broadleaf weeds actively growing in perennial bluegrass, perennial ryegrass, or tall fescue. Only emerged weeds present at the time of application will be controlled. Apply using equipment that assures uniform coverage of the target area. When treating mature plants or hard to control species, and for applications made during drought conditions, use the higher rates of HI-YIELD Triclopyr Ester. Applications made under drought conditions may provide less than desirable results.
Magic on Wild Violets
By Adrienne on 04/25/2017
I've been fighting with wild violets for about three years, tried a bunch of different products. Sometimes I'd knock them back a bit, and sometimes I'd knock the grass back a bit, but overall it was getting worse each year. This stuff works!! My only disappointment is that the violets were dead within a week; I would rather they had died a slow painful death, screaming for their mommies like little girls :) I used a pump sprayer. In 2 gallons of water I put 3 tbs Hi-Yield and 2 tbs surfactant. I sprayed just until the weeds were wet. I didn't use that blue marking dye but next time I'm going to try it. With so many violets it got hard to keep track of where I sprayed, and I missed some. Between the ones that I missed and the new ones that popped up since I sprayed, I'm going to have to do a second round. But at least now I'm winning the war. Die, you violets, die, die, die!!

Truly a Great Product recommendto me by an ag Lab
By Justin on 09/08/2016
Here is the thing it is 1 TBSP per gallon per the supplemental documents, which is 3 TSP = 1 TBSP. Get yourself a medicine measure from an old cough syrup bottle and dedicate it to herbicides (NEVER use it again for medicines or anything else). I used 1.5 (1 and a half) teaspoons and mixed it up in a dedicated sprayer with half a gallon of distilled water (it is free of all contaminants). From there I added 1 teaspoon of non-ionic surfactant for herbicides (because the product I used recommends 2 TSP/ gallon and I mixed up half a gallon.) Lastly, a blue dye that recommends 1oz per gallon. Two tablespoons is an ounce; hence one (1) tablespoon was what I used for half a gallon... In a gallon sprayer I put a nozzle on it that atomizes the spray and pumped to high pressure. Worked great completely curing my lawn of creeping vine Charlie and surges. I have Centipede grass which is a riskyer lawn to use this on per the instructions, but I had no lawn damage whatsoever on my TiffBlair type Centipede warm-season grass in West Columbia, SC. Your results may of course vary from mine which was 100% elimination of the weeds with no lawn damage, but I think most critical is the instructions by the manufacturer realizing that this small bottle is a potent product not forgiving in that you must measure accurately in teaspoons per gallon unlike diluted homeowner products. Alway wear the appropriate PPE and do a test spot to verify you have things dialed in.

Damned Wild Violets!

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!

Works Perfectly!
By Steve on 03/30/2014
Prior to my purchase of Hi-Yield, I had only bought the "other brand" of Turflon. For the uninitiated, this is the only product safe for killing bermudagrass and several other invasive grasses from your otherwise beautiful lawn. It kills many noxious weeds without destroying a nice Marathon lawn, for instance. The price I paid for this was a bit less expensive than the other brand and worked just fine.

I have a lawn that is 50/50 Bermuda and Fescue. I want the Bermuda dead!! and When is the ideal time to apply it?
Per the Hi Yield Turflon Ester Product Label: Apply HI-YIELD® Turflon® Ester Ultra at a rate of 1 quart per acre. Three to four additional applications at 4 week intervals will be required to give adequate suppression of Bermudag- rass and allow Fescue or other desired turfgrass species to dominate. To improve suppres- sion and control of Bermudagrass, To improve suppression and control of Bermudagrass, tank mix 1 quart of HI-YIELD® Turflon® Ester Ultra per acre with a postemergence grass herbicide registered for this use pattern. Three to four additional applications of this tank mix at 4 week intervals should be made to achieve control. Reseeding following application will accelerate the transition to Cool Season turf.
This product only control weeds that have already emerged and that are actively growing. If your yard has started going dormant at all and your temps are not above 65 degrees at least 5 days in a row at this point in the year, then you need ot wait until next year to apply the product as you will only see spotty results now.

Will this product kill the Bermuda grass that is starting to take over? My average lots are 100 x 75 I want this grass dead how much do I apply?? Will it harm the K31 grass?
Hi-Yield Turflon Ester Ultra can be used on tall Fescue to control Bermuda grass. Per the product label, the application rate is 3/4 fl. oz. of product per gallon of water. You will likely have to do multiple applications to gain full control of the Bermuda grass. Applications can be done every 3-4 weeks.

HI-YIELD Turflon Ester Ultra herbicide for the control of actively growing annual and perennial broadleaf weeds and kikuyugrass in perennial bluegrass, perennial ryegrass, or tall fescue. Marathon II lawns are commonly refered to as a dwarf tall fescue and because it is a specialty variety we are unsure of the effects of Turflon Ester Ultra on your turf variety. We would recommend performing a small spot treatment to test for sensitivity.

Hi-Yield Turflon Ester Ultra is a selective post-emergent herbicide that will be most effective on young, actively growing weeds listed on the product label. It will be difficult to get control using post-emergent herbicides once temperatures are consistently less than 60 degrees and plants are beginning to go dormant.

I have a lawn that is mainly backfill red clay and rock with only about 4 inches or so of top soil. Therefore, the pin oak tree has very shallow roots. How close to this tree (about 12 years old) can I spray Turflon Ester Ultra?
Hi-Yield Turflon Ester Ultra could affect nearby desirable plants if it were to contact them or the root system. We would not recommend applying this product at or near the dripline of any desirable plants.

Hi-Yield Turflon Ester Ultra is not labeled for poison oak and would not be recommended to be used for controlling it. The Bonide Poison Ivy and Brush Killer could be used for it.

After spraying our grass, my roses show stress and droop. Is it possible that over spray has harmed them? If so, can this be reversed?
The Turflon Ester label does not state any precautionary instructions for roses, but does advise, " Very small quantities of spray, which may not be visible, may seriously injure susceptible plants. Do not spray when wind is blowing toward susceptible crops or ornamental plants that are near enough to be injured. Spray drift can be reduced by keeping the spray boom as low as possible; by using higher volume sprays and lower pressures; using nozzles that deliver larger spray droplets; and by spraying when wind velocity is low."
We recommend contacting your local Master Gardener for help and recommendations on what products to you use and when the best time fram for treatment is to help reverse any damage done.

Grass is well established is a 10 year old lawn and the Bermuda grass is starting to grown on the edge is a 3 foot by 25 foot area, chocking out my K31 grass
Bermuda would be considered a grassy weed, so you need a product that is geared towards grassy weeds and not broadleaf weeds. We want to be clear that bermuda can be suppressed, but it is VERY difficult to kill completely. It will take multiple treatments to finally kill it. HI-YIELD Turflon Ester Ultra herbicide could be used to do so.

Yes, a non-ionic surfactant can be added to Hi-Yield Turflon Ester Ultra when being applied to wild violets. The mixing ratio for the surfactant is 1-2 teaspoons per gallon of water. However, if you are treating in your lawn, do not use a surfactant as you could burn your lawn.
