Eradicating Willows: Garlon 4 Foliar Spray for Bushy Regrowth

For **multi-stemmed, bushy willow regrowth** (no single trunk), basal bark and hack-and-squirt methods are impractical.

Recommended: Garlon 4 (triclopyr ester) Foliar Application

• **Timing:** **Early spring, full leaf-out** (max translocation to roots).
• **Rate:** Per label (typically 1–2% solution for foliar).
• **Coverage:** Thorough, uniform wetting of all foliage.
• **Adjuvant:** Non-ionic surfactant (0.25% v/v) if not in formulation.

Why Garlon 4 Over Roundup?

• Triclopyr is **more effective on woody brush** (willows, alder, etc.).
• Less soil residual activity than glyphosate near desirable plants.
• **Garlon 3A (amine)** works but more volatile; **Garlon 4 (ester)** preferred for foliar.

Follow-Up

• Monitor for resprouts; spot-treat.
• Expect 1–2 seasons for complete control.
