What they don't tell you about wheat very often is that people figured out that if you defoliate a wheat plant, it will shove its remaining calories into the developing seeds and then die. You can control the maturity of a wheat field by spraying it with RoundUp late in the season.

So where the reality versus PR for the decay rate of RoundUp in the environment leaves a very long safety margin with early season and pre-emergent uses of the stuff, whatever you sprayed a matter of weeks before harvest very much matters on variance between fields and between customer and manufacturer.

We may be feeding ourselves RoundUp here.
