Safe time to Spray Dicamba

After a number of inspections of dicamba affected fields, I can offer no good insights as to how to spray dicamba safely.  Prairie Farmer recently published and article on How to Hit Dicamba's Narrow Application Window.  Volitilization and re-volitilizatoin seem to be factors in many of the cases we have looked at.  Temperature inversions must be to blame.  It is easy enough to cover wind speed and buffers, but how do you avoid inversions that are not readily apparent at application time.  The Pocket Spray Smart App may be helpful according to the article above.  The app attempts to predict inversion conditions 72 hours out.  The label for new dicamba formulations are only approved for only one more year, so if you think we need this tool in the weed control box, we need to do a lot better next year.
