Will Eliminator Weed Killer Control Poison Ivy, Oak, and Sumac?

Glyphosate Products for Woody Vine Control

Eliminator® contains glyphosate—the same active ingredient in RoundUp®. It translocates through green tissue to roots, making it effective on poison ivy, oak, and sumac when applied correctly.

Application Protocol for Woody Vines

Timing

• Best: Late spring to early fall (active growth, full leaf)
• Avoid: Dormant season, drought stress, rain within 6 hours

Technique

1. Cut vines at waist height (if climbing trees/structures)
2. Spray foliage to wet—not runoff
3. For ground-running vines, spray full leaf surface
4. Add non-ionic surfactant (0.25-0.5%) for waxy leaves

Follow-Up

• Wait 8-10 days for translocation
• Re-treat any regrowth (woody vines often need 2-3 applications)
• Monitor next spring for root-sprout emergence

Safety & Legal Notes

• Glyphosate is non-selective—protect desirable plants with cardboard shields
• Wear gloves, long sleeves, eye protection
• Urushiol oil (rash cause) remains active on dead vines—handle with gloves
• Check local regulations on glyphosate use

Alternative for Sensitive Areas

Triclopyr (Brush-B-Gon®, Garlon®) often works faster on woody species and has less soil activity. Better near desirable trees/shrubs.

Persistence wins: established poison ivy/oak/sumac root systems are extensive. Plan for multi-year management.
