>*that is to say, "growing glyphosate resistance" among weeds, not the public, though that may turn out to be the bigger resistance problem.
This is a HUGE problem. Palmer Amaranth is a weed with thousands of seeds. It can take over a pasture in a summer and grow big enough to break a combine sickle in a few short months. It's damn near resistant to everything, but it can be choked out with oats as a cover crop.
Dad found that by accident when there was a grasshopper plague. In the areas of hte field where the grasshoppers got the oats was Amaranth. The rest of the field was clear.
