Two modes of action are always better and make a more effective kill. For a few dollars an acre it's a no brainer. Roundup is only effective on broadleaf weeds under a few inches tall unless higher rates of both sticker and Roundup are used. It is cheaper to add the 2,4-D. Anything that is woody stemmed will only be defoliated by Roundup. It will be back later. Anything in a rossette with a taproot will only be stunted. Some weeds that are airborne like marestail won't even look sick after an application of Roundup. By airborne I mean seed that travels miles by air.
Unlikely to occur in this case but Roundup resistant weeds come from only using one mode of action.
Also, not trying to be disagreeable 88 man, just from a farm perspective that's my thought process. Sounds like you know your stuff though.
