You gotta love the timing. The gly/RR pair comes out and productivity goes up. Gly develops the reputation as one of the safest herbicides available especially compared to what farmers used pre-gly. Over time we begin to hear about gly-resistant weeds becoming a problem. Just about the time when farmers begin to look for alternatives, new GMO/Herbicide combinations come out. We then are hit with an activist campaign about the health impact of gly.
Regardless of the legitimacy or hype of claims on either side, I really find the timing interesting. When trying to unravel an enigma...follow the money!
