Dicamba Damage Heats Up

Dicamba damage is the buzz in agriculture right now.  New formulations were haled as the answer to drift issues with dicamba.  Industry officials are blaming everything except that dicamba is a bad idea.  Prairie Farmer has published a Monsanto Response that seems to be weak in some ways.  Drift is only one problem.  The field below had damage across the whole field.  That is likely caused by inversion.  We have heard that even a heavy dew on recently sprayed fields can cause a problem.

Some commercial applicators have quit using dicamba because of the issues.  If you continue to use it, be sure to follow label and understand that conditions can change quickly.  You may start a field on label and finish off label.  Dicamba residues in the tank have been blamed in some cases.  I am not sure how often that happens.  This article on what is happening in Illinois seems to cover many of the issues very well.  Monsanto claims that used as directed there should be no problems.  I am not sure I would use it at all.
Cupping indicates dicamba damage.
