TrueSet II Herbicide (2.5 Gallons)

TrueSet II Herbicide - Triple-Mode Residual Control for Field & Silage Corn

TrueSet II Herbicide delivers robust early-season weed control in corn with a proven three-active premix of acetochlor, clopyralid, and flumetsulam. This combination provides rapid knockdown plus long-lasting residual activity on tough annual grasses and small-seeded broadleaf weeds, helping protect crop emergence, stand establishment, and yield potential.

Key Benefits

• Three modes of action — Groups 15 + 4 + 2 support broad-spectrum control and resistance management.
• Knockdown + residual — strong foliar and soil activity to keep rows clean through early growth stages.
• Flexible timing — labeled for preplant, pre-emergence, or early post-emergence applications in corn.
• Program fit — tank-mix compatible to broaden the spectrum and layer residual in comprehensive corn programs.
• Safener included — contains dichlormid for improved crop safety when used as directed.
