RoundUp is the trade name for glyphosate, which is an herbicide, not a pesticide. RoundUp Ready is the trade name for glyphosate-resistant strains of crops. RoundUp and RoundUp Ready are both copyrights of Monsanto.
Thanks for the correction - that's been a long term misconception of mine, apparently. I thought pesticides as a term excluded herbicides (basically catch all term for insecticides, rodenticides). Seriously, I appreciate that very much.
