Equine feces. It has more to do with how it has been used.

Regardless of the method of application, gylphosate resistance is effectively eliminated by rotating crops or alternating herbicides.

Now listen carefully, YOU DON'T ROTATE CROPS IN THE WILD. Alternatives in riparian areas that don't require massive bureaucracy are few. Good grief.

I'm not a farmer I just put in a big garden every year. I also have a very large natural area filled with native plants that I call five acres of unmowed pasture, I don't try to tend it very often so I'm not in your position. But it seems you are addressing the issue from a different point of view than the rest of us.
I said in the beginning that I thought most of the uproar over the engineered seed had died down because the benefits were out stripping the mostly perceived problems. People were growing better crops and therefore prospering. You,no offense, seem to be taking what I would call a liberals stance and are looking for the harm as it affects you personally.
The round up resistant weeds are a problem for you,with what is essentially a flower garden. Proper farming practice avoids this dilemma and allows the crop grower the benefit.
If you are growing a native plant area then you might want to approach the weed problem with a more natural method.
Weeds are part of nature too... you should see the broom sage out behind my house, I keep telling my wife it's pretty. She's not going to buy that much longer though.

OK, so alternate herbicides. (...and if you have to get a license to do so, take the time to get one)

My point is this: Monsanto's development of Roundup as an over the crop selective herbicide has done more to improve the efficiency of American agriculture than anything else in my lifetime. 30 years ago, the notion that a farmer could not only raise a crop without tearing up the soil and exposing it to erosion, but could do so at less cost and with a higher yield than with conventional tillage would have been laughable. That's how we farm now.
