Herbicide Antagonism

What do you know about herbicide antagonism?  The label may say that one should not cultivate and then spray within a certain time window.  What do we know about mixing herbicides that might reduce the effectiveness of one or more of the weed killers?


I'm not sure the label is a good enough source of information.


What is your experience?  I'm working on my 2019 herbicide plan.  I do my own spraying.
