> Glyphosate is not approved for organic use so that's an irrelevant point.

Actually it is a pretty interesting point.

Saying "there's less glyphosate therefore less pesticide" is poor reasoning, because glyphosate is replaced with other, generally more toxic, pesticides in organic crops.

It's interesting that organic crops have glyphosate despite it being banned for use with them, but that's a separate discussion.

No it isn't. Glyophosate is broadspectrum herbicide for use with gmo glyophosate resistant crops only, there is no organic analogue to this. Also consider that the concentration used is much higher for glyophosate application and the reduced ability for it to be filtered from ground water creates additional externalities.

There is indeed no organic analog for glyphosate. But there are other pesticides that are routinely applied to organic crops, such as copper sulfate, pyrethrin or rotenone. Both copper sulfate and rotenone are moderately toxic to people, and rotenone is highly toxic to fish.

Rotenone (which has it's usage restricted in omri) and pyrethrin are pesticides, copper sulfate is anti fungal; these non synthetic moderately toxic treatments are replaced with other, generally more toxic treatments in non-organic crops.
