• Harmony Extra and Express can be applied in the fall and/or spring up to 45 days before planting corn or soybeans for control of wild garlic and other broadleaf weeds.
• Harmony Extra is a premix of thifensulfuron (Pinnacle) plus tribenuron methyl (Express) that controls wild garlic and annual broadleaf weeds, including lambsquarters, mustard species, Pennsylvania smartweed, field pennycress, and shepherdspurse. Express controls purple deadnettle, chickweed, and field pennycress, and provides partial control of shepherspurse and otehr mustard species.
• Mode of action: ALS inhibitor.
• To control wild garlic, apply 0.5 to 0.6 ounce or Harmony Extra when garlic plants are less than 12 inches tall with 2 to 4 inches of new growth. Control will be better if applied during warm weather (60 F or more) to actively growing garlic plants. Thorough spray coverage of garlic plants is essential.
• Apply with crop oil concentrate (1% v/v) or nonionic surfactant (0.25% v/v). Use flat fan or low-volume flood nozzles for best results.
