Hi-Yield Triclopyr Ester - Questions & Answers

We would need to know what specific product of Ferti-lome you are wanting to mix together in order to advise if mixing the Hi-Yield Triclopyr Ester Ultra would be permitted. You may also check the product labels for "tank mixing" instructions on if and how the product is able to to mixed. 

What area are you using the Prodiamine over?  Hi-Yield Triclopyr Ester Ultra is not labeled to be used in all lawns types like the Prodiamine can be.

Hi-Yield Triclopyr Ester Ultra is not labeled for use on Centipede grass because it will harm it.  Additionally, this product does not kill Bermuda, but rather only suppresses it. 

Hi-Yield Turflon Ester Ultra can be used on perennial bluegrass, perennial ryegrass, or tall fescue, and on ornamental turf including these turfgrasses in golf courses 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 Triclopyr Ester would be mixed at the rate of ½ to 1 pint per acre when tanked mixed.  This equals ½ to 1 tsp per gallon if it takes you 100 gallons to cover the acre.

The application rate for Hi-Yield Triclopyr Ester will vary depending on where and what you will be treating.  Please refer to the product label for specific application instructions. 

Hi-Yield Triclopyr Ester is not labeled for cut stump applications.  But Remedy Ultra Herbicide is a similar product that is labeled for this use.  Cut Stump: 20 to 30 gallons with oil to make 100 gallons and Spray the Root Collar area, Sides of the Stump, and the Outer Portion of the Cut Surface, until fully wet.  You will use basic safety supplies when applying Nitrile gloves, boots, and safety glasses. 

Hi-Yield Triclopyr Ester and Metsulfuron 60 DF are applied to turfgrass only and are not labeled for removal of palmetto on plants. 

Hi-Yield Triclopyr Ester is not safe for use on bermuda.  It is actually used to control berrmuda in certain turf types.

Hi-Yield Triclopyr Ester is best applied to well established fescue.  This is usually after it has been mowed at least twice.  Be aware this product is not labeled to be used on residential lawns though.

Hi-Yield Triclopyr Ester is only labeled to be used on some cool season turf, perennial bluegrass, perennial ryegrass, or tall fescue.  Refer to the product labels of tank mix products and follow all appropriate use directions, precautions, and limitations

Per the Product Label of Hi-Yield Turflon Ester Ultra, it cannot be applied to bahiagrass, bentgrass, bermudagrass, centipedegrass, St. Augustine grass, or zoysiagrass unless turf injury can be tolerated.

The product label for Hi-Yield Triclopyr Ester states, "Do not make direct applications or allow spray mists to drift onto cotton, fruit or orchard trees, shrubs, grapes, peanuts, soybeans, tobacco, vegetable crops, flowers, citrus, or other desirable broadleaf plants."  We would recommend carefully spot treating the oxalis directly while avoiding any contact with desirable plants.

No, Hi-Yield Triclopyr Ester is not labeled to control nut sedge. Sedgehammer + would be a great alternative for sedge control, but be sure to check the product label for use instructions and areas its safe to be applied. 

Hi-Yield Triclopyr Ester is not labeled to control lesser celandine, so we are not sure if it would be effective. Lesser celandine is a very difficult plant to control, and you will probably have to use a non-selective herbicide such as RoundUp QuikPro to spot treat it carefully. Herbicides which contain the active ingredient glyphosate, such as Round Up, are effective in controlling (but not necessarily eradicating) lesser celandine. Applications should be made in late winter or early spring when leaves are visible, but prior to full flowering, and when temperatures are above 40°F. Glyphosate will impact other vegetation so try to target only the celandine. It may take 1-2 weeks before the full effects of the treatment are visible.

Thanks,

Hi-Yield Triclopyr Ester is not labeled to control hairy bittercress. If you let us know what type of turf you have we can recommend something for you. 

Per the label, Hi-Yield Triclopyr Ester should not be applied to warm season grasses, including zoysia grass, unless you know turf injury can be tolerated.

Hi-Yield Triclopyr Ester is labeled for Ground Ivy but not English Ivy. With English ivy, because it of the waxy leaves, we recommend using a brush killer such as Bonide Poison Ivy and Brush Killer.

We do not recommend coming Q4 Plus Herbicide with other post-emergent herbicides such as Triclopyr Ester. The Q4 already contains 4 active ingredients and covers a wide variety of weeds, so adding more active ingredients could damage your desirable turfgrass.

While you can add a surfactant with Hi-Yield Triclopyr Ester, we do not recommend adding it to Q4 Plus since that can increase the risk of injury to your desirable turf.

If you would like to tell us more about what specific weed(s) you are targeting, then we are happy to offer additional recommendations. Be sure to read and follow the product label(s) of any herbicide(s) that you are using.
