We always see a yield drop in wheat in corn stubble compared to bean stubble but always assumed some atrazine carryover as likely.

Everyone shoots for 80 or 90 bushel wheat but generally you need to keep a skeptical ear when someone around here claims to have 100 bu wheat. Always tends to be that 10 seconds on the yield monitor that they guy remebers seeing not that the field actually averaged that much. :)

In SW IL its a hard thing to do. Plant early to maximise yield but you risk Hessian fly infestations.(fly free date is mid October here) Spray Harmony for garlic and winter anuals but you can't do anything if you have heavy cheat grass in the spring and that will destroy your wheat crop. Hope for cool weather when polinating but not wet weather or the fusarium will ruin the test weight.

All good fun yet we just keep doing it anyway.
