This product translocates into the root system to stop resprouts and keeps more than 20 woody species at bay. It is not available for sale in several states, so verify local restrictions before purchasing.
Why selected: It provides strong translocation to roots and effective suppression of regrowth, making it a reliable choice for larger weed trees and stubborn brush in right-of-way sites.

Why selected: Combines stump killer action with weed and vine control in a single product, offering convenient use across multiple tasks, including foliar applications.
Caution: Undiluted use on stumps is effective but may require follow-up treatments in dense root systems. Test a small area first to confirm efficacy on stubborn species.

Buying Guide
Key considerations when choosing a tree-killing herbicide:
- Application method: Do you need ready-to-use RTU, concentrate, or spray-on formulas for brush and vines?
- Target species: Which woody plants are common on your site (ash, oak, ailanthus, brush, vines)?
- Site type: Fence lines, roadsides, forests, pastures, or wetlands influence product choice and label restrictions.
- Environmental impact: Consider non-target vegetation and soil health; ensure selective action on woody plants.
- Regulations: Some products have state-specific sale restrictions; confirm local rules before purchasing.
- Visibility and coverage: Dyes or clear formulas impact application accuracy and waste reduction.
How to apply effectively
- Inspect the stump anatomy and choose the method (cut-stump treatment vs. foliar spray) that aligns with the plant’s condition.
- Follow label directions for timing, dilution (if any), and protective equipment.
- Apply during appropriate weather windows to minimize drift and ensure translocation to roots.
- Monitor treated areas for resprouts and re-treat if necessary, following product guidelines.
