Is it worth an extra sprayer pass to keep a pre emerge herbicide out of fertilizer?

I've felt for years that adding a pre emerge herbicide such as SureStart/TripleFlex or Outlook when broadcasting fertilizer is not giving me quite as much bang for my buck. Local co-op has been doing it this way when they put down 28% before corn is up, but in my opinion the weeds that get hit with the 28% shutdown or "burn" before the herbicide can do any good. Does anyone have any data one way or the other on if it it should be in a separate pass? And is it worth it?

The idea of pre emerge herbicide is also before weeds emerge. If you're no till then youll want a burn down. The pre chemicals target seed germination. Also chemicals that work in mn might be different from what work in ar

Outlook isn’t going to kill weeds anyway. Not sure about the other two.
