Its a broadleaf herbicide, similar to what is in the now-banned lawn herbicides "weed and feed" and "killex". Its used in forestry applications, spread from planes. They want to kill the soft maple and poplar so the pine/spruce can get started. There is supposed to be signage in the area indicating pesticides have been used there. I've found these on cut-overs in the Pembroke area.

I have never seen it spread by plane. I have spread it by hand with a tanker truck and sometime back pack sprayer.

My company has tested 1000s of groundwater samples from all over southern ontario and had them analyzed by independent third party laboratories for glyphophate and numerous other common agricultural and industrial chemicals. Not one of those samples has ever come back positive for any detectable amount of glyphosphate. Some of those samples were taken from wells 20 or 30 feet from heavily sprayed bean fields.

Surface water on the other hand is a different animal and trace amounts will regularly show up in creeks and ponds close to spray areas.
