Well then,,,,, keep your seed up there!!!!  LOL 

Here we have plenty of resistant weeds (mostly pigweed, or water hemp) but,,,,,, the RU still works on the non-resistant ones, only leaving a certain percentage in the field.  Plus,, we still kill sunflowers, grass, keep morninglory under control (if you consider making a morninglory a minature one control) and,,,, when mixed with a 'partner' such as ATZ, reflex, goal, staple, valor, etc we still wind up with relatively clean fields.
