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 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.
Per the product label, it is recommended that you wait at least three weeks after applying Hi-Yield Triclopyr Ester Ultra to seed the treated area.
Since Gordons Ornamec Over-The-Top Grass Herbicide does not give instructions for tank mixing with other products and would not be recommended to be mixed with Hi-Yield Triclopyr Ester but can be used around the same time in beds/landcaped areas as directed on the product labels.
Hi-Yield Triclopyr Ester should NOT be applied to zoysiagrass, bentgrass, bermudagrass, centipedegrass, St. Augustinegrass, bahiagrass.
Unfortunately, there are not many products labeled for greenbriar vines. A non selective such as Glyphosate 41% and Triclopyr are recommended for direct applications to freshly cut vines and stump applicaitons. Hi-Yield Triclopyr Ester is only labeled for broadleaf weeds in cool season turfgrasses.
Fertilome Brush Killer and Stump Killer containing Triclopyr would be recommended for direct treatments to cut vines, woody brush and stump applications. For treating greenbriar in pastures, PastureGard HL is labeled to treat greenbriar vines. Please view the full product label for more information.
This article by the University of Georgia Extension mentions that the best time to treat is in the spring when the leaves are fairly young. If vines are well established, it will take multiple applications to control it.
Hi-Yield Turflon Ester Ultra is labeled to suppress bermudagrass in Tall Fescue and recommended to be applied at the rate of 3/4 fl. oz per gallon of water per 1000 sq ft. Three to four addtional applications are recommended at 4 week intervals for suppression of bermudagrass and to allow the desired turfgrass to overcome the lawn.
Please view the Suppression of Bermudagrass Section on page 17 of the product label for more information.
Hi-Yield Triclopyr Ester is not specifically labeled for English Ivy. For cool season turfgrasses, Bonide Poison Ivy and Brush Killer BK-32 Concentrate can be used to treat English Ivy at the rate of 4 fl oz per gallon of water per 1000 sq ft.
Due to the waxy coating on the leaf surfaces, direct application to the leaves with a paintbrush may work best. Applications should be made during warmer temps when the ivy is actively growing or if new sprouts or growth occurs.
Hi-Yield Triclopyr Ester cannot be used on Zoysia as it is for cool season turfgrasses only.
To kill or elimeinat bermudagrass in zoysia you could consider using Gordons Ornamec 170 Grass Herbicide as it is labeled to suppress and eventually control bermudagrass in Zoysia. This can take multiple applications or seasons to eliminate bermuda complteley.
Please view the product label for more information.
Hi-Yield Triclopyr Ester should not be used over the top or around anything desirable as it an injure plants if contact is made. Instead you should use a grass killer like the Bonide Grass Beater II Over-The-Top Grass Killer
The Hi-Yield Triclopyr Ester is not labeled to treat for Monkey Grass.
For monkey grass, we would recommend spot treating with a glyphosate product such as Gly Pho-Sel Pro 41% with a surfactant.
The best time to treat wild violet is typically in spring when they are young and first begining to flower as they are more sensitive to selective herbicides. Hi-Yield Triclopyr Ester can be applied anytime weeds are actively growing and for wild violets, it will take multiple repeat applications to get some control.
To prevent weeds from germinating, a pre emergent is going to be your best option as the Hi-Yield Triclopyr Ester is only going to kill actively growing weeds and will not prevent new weeds from germinating.
Unfortunately, there is not a pre emergent specifically labeled to prevent wild violet but applying pre emergents in early spring and late fall will help the overall health of your lawn and help reduce weed growth during the warmer months.
