Mesquite (Prosopis spp.) is a major weed (invasive alien species) in Australia and several other countries.
Tebuthiuron pellets are often used for woody weeds of rangelands but its seems mesquite has been largely over-looked (at least in Australia) as a target for this herbicide due to perceived lack of a commercial market or perhaps a lack of testing (as it's not a registered product in Australia).
Are there examples of successful use of tebuthiuron-based herbicides for mesquite?
Thanks for replying Mohammad.
Discussions with a former Dow AgroSciences representative indicate it was effective but not registered (in Australia).
Honey mesquite (Prosopis juliflora) was not controlled by tebuthiuron at 2.2 or 4.4 kg/ha on rangelands in Texas.

Thank you for the answer Andrew. I am not surprised by the lack of efficacy at the tested rates. In my region we use 20% tebuthiuron at 12 to 15 kg/ha to achieve effective control of other woody weeds such Vachellia nilotica. I would expect Prosopis spp. to require about the same latter rate for good efficacy but I have not heard of any field results.
