Should I herbicide before no-til??

Post-emergent does not have to be for a genetically engineered crop. It has
been used for decades. If one is growing corn (a grass), a post-emergent
herbicide to only kill broadleafs can be used without affecting the corn.
If one is growing soybeans (basically a broadleaf), a post-emergent herbicide
to only kill grasses can be used without affecting the soybeans.

Post-emergent herbicides are used all the time in orchards, nurseries,
berry crops, etc. without problems. Best to read the label and follow it,
no matter what terminology you wish to call it.

The reference was to post-emergence was related to burndown, not for the use of selective chemicals. Post emergence selective chemicals have been around for decades, of course. Probably a poor description on my part.

I'd spray it one weekend and drill it the next. You could do it the same day if you wanted.

I'd go a little deeper on the corn if you are planting them separate, 1.5-2". The beans will work just fine at 1".

If you need to split the difference to plant them together, no more than 1.25" deep because the beans do not like to go deeper.
