Stump-Out Stump & Vine Killer
Bonide’s Stump-Out is designed to control woody plants and vines, with a multi-use profile that includes stump killing and foliar spray options. It targets broadleaf weeds and vines while providing a fast-acting solution for stump removal. The product can be used undiluted on stumps to prevent sprouting, or diluted for foliar applications via hose-end or tank sprayers. This versatility makes it suitable for quick, on-site stump management alongside landscape maintenance.
Tordon RTU Specialty Herbicide
This Dow AgroSciences formulation is designed to kill cut stumps and select woody plants in fence lines, roadsides, and non-cropland areas. It relies on systemic action to translocate into the root system and stop resprouts, helping manage unwanted trees and woody vegetation in a controlled manner. It is noted to be effective against a wide range of woody species, making it a robust option for property maintenance and rights-of-way projects where targeted woody control is required.
Roebic K-77 Root Killer
Roebic K-77 focuses on sewer and septic systems, clearing and stopping new root growth that can cause clogs. Its copper-based formula targets roots at pipe entry points while aiming to prevent re-growth, supporting long-term pipe health and drainage. It is non-corrosive to plumbing and soil life, making it a practical solution for maintenance around drainage infrastructure while protecting nearby vegetation.
Root Destroyer – 2lbs
Root Destroyer uses copper sulfate crystals to kill invasive septic and sewer pipe roots without harming adjacent trees. It is designed to temporarily reduce bacterial action, with normal activity expected to resume in about 15 days after treatment. This product is positioned for targeted root control near plumbing and drainage lines, balancing effectiveness with environmental considerations around trees and shrubs in the vicinity.
Fertilome Brush Killer Stump Killer
Fertilome’s Brush Killer Stump Killer is designed for stumps and woody plants, including vines and brush. For stump application, use the product in its current form and apply with a brush for targeted control. The label suggests mixing 8 oz of concentrate in 1 gallon of water for spray-on foliage treatment, offering flexibility for both stump and foliar applications depending on the infestation.
Ready-to-use Stump Stop
Ready-to-use Stump Stop from OMNI DEPOT provides a pre-mixed solution for immediate application. It is marketed for use across diverse settings—forests, pastures, roadsides, fence lines, and wildlife areas—where control of woody vegetation is needed without steps for mixing. The product emphasizes convenience and broad application sites, including hard-to-maintain areas and infrastructure corridors.
Buying Guide
Key considerations when selecting a root killer for trees and stumps:
- Target site and plant type: Choose products designed for stumps, woody vines, or root invasion near pipes and drainage. Some formulas are optimized for non-crop areas or rights-of-way.
- Mode of application: Stump-specific products offer undiluted applications, while others are foliar or spray-based. Consider whether you need direct stump treatment, foliar control, or ongoing maintenance near plumbing.
- Translocation and speed: Systemic herbicides that move within the plant can prevent resprouts more effectively, while copper sulfate-based products focus on root intrusion at entry points.
- Non-target safety: Review labels for effects on surrounding trees, ground cover, soil bacteria, and septic systems. Some products claim non-corrosive properties for plumbing and pipes.
- Environmental and regulatory considerations: Some products have regional restrictions; verify local guidelines before use.
- Re-entry and protection: Observe required re-entry intervals and protective equipment recommendations to ensure safe handling and use around people, pets, and wildlife.
- Cost and coverage: Compare container sizes, dilution requirements, and estimated coverage to match your project scale and budget.
In selecting a product, align the choice with the infestation level, the proximity to structures, and whether you need a stump-centered or root-intrusion-focused solution. For pipelines and sewers, consider formulations designed expressly for root control in plumbing. For landscape-wide control, a ready-to-use or foliar option may offer faster results with simpler application.
