Roundup Tree Killer

Having a problem Palm tree at the moment, and needing something to reduce the palm trees life, I was told to look at Roundup as a solution.  Well, I thought that was just a lawn weed treatment, until I checked into it fully.

Two products from the Manufacturers website:

	Roundup® Concentrate Use Roundup® Concentrate on all weeds and unwanted grass or as a stem injection to kill unwanted trees and woody weeds. Contains 360 grams/litre glyphosate. Roundup® Concentrate has a sophisticated surfactant technology that enhances performance.
	Roundup® PowerMax™ Concentrate Super strength formula is perfect for hard-to-kill weeds and problem trees. Contains 540 grams/litre glyphosate. Roundup PowerMAX has been formulated with a unique cutting edge surfactant system that is designed to maximize uptake of the herbicide by the weed. Don’t store mixed up solution for more a few days.

It looks like it may be the Glyphosate that does the trick.
The normal Roundup weedkiller packs would appear to have a very low concentration of this ingredient.
