It would if you bagged the whole tree and gave it a big dose. Not subtle.
Salt or ethylene glycol would be easier but both are still on the stupid side.
Mimosa (I think that's what you mean) are fairly readily killed by cutting and stump grinding. If you can't stump-grind, spray any regrowth with herbicide and once the tree is really dead break up the stump with drilled holes or an axe or splitter, cover in manure to promote decay by upping the available nitrogen, cover in dark plastic, wet and wait while it rots away.
Ammonia will be converted into fertilizer by soil microbes which will stimulate growth. A natural organic herbicide formula is: Orange oil/vinegar mix (2 ounces orange oil per gallon of 20% vinegar plus 1 tbsp. of molasses, 1/4 tsp. of liquid dish soap) makes a NON-SELECTIVE herbicide. Cut down the tree. As the foliage resprouts, spray the new growth with the above mixture. It may require repeated applications to kill the tree completely. After the tree is killed you can bore holes in the stump (1/2 inch spade bit) and fill each hole with saltpeter which you can get from a pharmacy or perhaps an agricultural supply store. It is often sold as a "Stump Remover."

removal of tree and then stub removal to prevent regrowth best
An axe would be quicker?
