HPPD or Status?
This one decision affects every other herbicide choice you make in corn this year, and it also may impact what crop you rotate to next year…

In terms of the primary post-emerge broadleaf herbicides in corn, there are two choices:
HPPD (e.g. Callisto, Laudis, Impact, Armezon, generics)
Status (diflufenzopyr plus a corn safener plus a small amount of dicamba)
