Control of Brazilian pepper trees can be tricky, and which herbicide is best will depend on the time of year and method that you are using. Something like RoundUp QuikPro (glyphosate and diquat) will likely only work on seedlings, and may take several weeks to kill the young plants.
Crossbow Specialty Herbicide can be used for basal bark treatments in general. However, the product label does not specifically list Brazilian pepper tree as a plant that it controls.
This article from the Florida State Extension offers the most detailed recommendations for treating this invasive plant.
They recommend using Triclopyr Ester for basal bark treatments, which we carry in Hi-Yield Turflon Ester Ultra or Garlon 4 Herbicide in a pasture. Usually direct stump treatments offer the fastest control, however this is best done when the trees are not fruiting since seeds may be scattered and start new plants.
