In the past, Monsanto has required farmers buying Roundup-Ready seeds to sign license agreements stating that only Monsanto glyphosate may be used.

I smell a rat here - perhaps they are selling glyphosate as a name on the product, but in reality there is so little of it compared to 'filler' weedkillers that they can profit from that too.
the whole world knows that glyph kills it all, so "glyph-ready" seems like a contradiction to me
source info comes from my time dealing with sugar cane producers who use pure glyph to increase the sugar content in the useful end of the canes they harvest
