I'm assuming that milo is the same as grain sorghum? 

I have run across a product called Facet L, from BASF.  From what I understand, it is typically used "down South" in rice production.  It has on the label "in crop use in grain sorghum".  I suggest going to CDMS, downloading a label and reading thru it. I looked into it earlier this spring, and found it is not readily available " up north here". So, if you are interested, you might have to see if your distributor can/will order it in for you.

If some of the guys from down south are reading this, maybe they can chime in with any experiences they have with this Facet L.
