It is my understanding that applicators when they apply Engenia or XtendiMax must have on hand a copy of the 24c label for those herbicides.  A hard copy is preferred. Baring that a downloaded copy on to your Ipad, tablet or phone would be better than nothing.  Trying to down load a copy on to your phone as the TDA inspector pulls into your field is not recommended. The links so you can down load, print a copy and read before you go spray is:
