You can mix Hi-Yield Triclopyr Ester with Tenacity for post-emergent weed control. This combination is recommended for control of tougher weeds including clover and wild violet as well as additional control of common Bermudagrass and black medic, per the supplemental label here.
We still recommend this as a spot treatment only. This combination should be used only on tall fescue, Kentucky bluegrass, and perennial ryegrass.
Hi-Yield Triclopyr Ester can be mixed with water as directed and a dye indicator can be added.
Hi-Yield Triclopyr Ester is best applied to dry areas. Slightly damp is ok but you do not want to apply when grass/weeds are soaked. Typically best applied when no rain is expected 24 hours before or after rain.
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.
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.

We have been unable to find any articles that list that triclopyr can be used for stump treatment of banyan trees specifically. A typical stump treatment would involve first cutting down the tree, and then treating the fresh cut stump by brushing on an herbicide such as Fertilome Brush Killer and Stump Killer rather than the Hi-Yield Triclopyr Ester Ultra. This article suggest burning the stump after creating a trench around the base and roots, however, we recommend checking with your local Department of Agriculture as to what is allowed in your area regarding burning. Either way, the tree would first have to be cut down before herbicides or other techniques could effectively prevent regrowth.
Hi-Yield Triclopyr Ester is not labeled to treat johnsongrass. It targets broadleaf weeds. Gordons Ornamec Over-The-Top Grass Herbicide will kill johnsongrass around established listed ornamentals. Ornamec will control Annual Johnsongrass seedlings (sorghum halepense) when 2 to 8 inches tall, before tillering or heading. It will control perennial rhizome johnsongrass that is 8 to 18 inches tall and before booted stage, per the product label. You may need multiple applications for more mature plants. We also suggest using a pre-emergent herbicide in the future for the best control of Jonhsongrass and many other difficult weeds. Prodiamine 65 WDG is safe to use around most turf and ornamentals. If treating the grass in the lawn, please provide the desired turf species for a recommendation.

When using the Diquat you will need to mix it at the rate of 2-4 oz per gallon of water and mix it with an 80% nonionic surfactant.
