Is it Harmony or Harmony Extra?

From Iowa State http://www.ent.iastate.edu/Ipm/Icm/1993/2-12-1993/harmxtra.html

Harmony Extra is not registered for use in corn nor soybeans. Harmony Extra is a prepackage combination of DPX-L5300 and thifensulfuron. Thifensulfuron is the active ingredient in Pinnacle. Neither thifensulfuron nor DPX-L5300 have any soil residual activity. However, DPX-L5300 has considerable activity on corn and soybean. The use of Harmony Extra will likely result in serious crop injury.
