Kyro Herbicide (2.5 Gallons) (Acetochlor)

Kyro Herbicide - Triple-Mode Postemergence Residual Control for Corn

Kyro Herbicide combines the power of acetochlor, topramezone, and clopyralid to deliver fast knockdown and long-lasting residual control of tough annual grasses and broadleaf weeds in field corn, seed corn, silage corn, and popcorn. Its encapsulated formulation provides dependable performance and a broad application window when used as directed.

Key Benefits

• Three modes of action — Groups 15 + 27 + 4 for robust spectrum and resistance-management strength.
• Knockdown + residual — HPPD activity (topramezone) delivers rapid foliar control while acetochlor extends soil residual.
• Tough broadleaf performance — clopyralid enhances control of key broadleaves to keep rows cleaner, longer.
• Flexible tank-mix fit — integrates with common POST programs; follows and layers with PRE foundations.
• Designed for corn — labeled for field, seed, silage corn, and popcorn with strong crop safety when used as directed.

Application Rates & Timing

Apply postemergence to small, actively growing weeds within the growth-stage window specified on the label. Select rate by weed spectrum, weed size, and corn growth stage. Include the required adjuvants and follow all spray volume, carrier, and interval directions on the label. Residual activity is optimized with timely rainfall or irrigation to activate the soil barrier. Rotate modes of action and use within a layered program for season-long control.

ALWAYS READ AND FOLLOW LABEL DIRECTIONS BEFORE USE.
