Herbicides, not pesticides. Also, keep in mind that "herbicide" is not a single thing; the particular herbicide that Monsanto sells (glyophosate) is more-or-less not toxic to mammals or insects and does not migrate to the water table. You can't just compare "pounds of *cide" and call it a day. It is very important how much of which pesticides and herbicides are being applied, and what the properties of those are (how long they take to break down, whether they migrate to the water table, how toxic they are to different animals).
