It works effectively as a stump killer when applied undiluted directly to freshly cut stumps to prevent resprouting. The formula also controls undesirable broadleaf weeds and plants.
It can be used as a foliar spray applied with a hose-end or tank sprayer, making it versatile for removing invasive vegetation from around properties. The concentrate is especially useful for maintaining clear areas free from competitive plant growth by targeting the root systems of unwanted plant life.

Dow AgroSciences’ Tordon RTU Specialty Herbicide is formulated specifically to kill cut stumps and woody plants in non-cropland areas such as fence lines, roadsides, and rights-of-way. It effectively controls more than 20 woody species by translocating into the root system, which stops resprouting.
Designed for targeted use, this herbicide is not available in all states (excludes CA, AK, FL, DC, RI, and PR). The ready-to-use formulation allows for easy application on cut surfaces to eliminate tree roots and prevent regrowth, making it ideal for long-term woody plant management.

Roebic FRK Foaming Root Killer Granules
The Roebic FRK Foaming Root Killer is designed for severe root intrusion problems in sewer lines and pipes. The foaming action allows the product to fill the entire pipe, attacking roots and preventing new growth without damaging surrounding trees.

Buying Guide: Choosing the Right Root Killer for Trees
When selecting a root killer, consider the following important aspects to ensure effective and safe treatment:
- Intended Use: Determine if you need a product for stump and sprout control, or for clearing roots from plumbing and septic lines. Some formulas are specialized for landscaping, while others are designed for pipe maintenance.
- Active Ingredients: Products with copper sulfate or dichlobenil are effective at killing roots, but the environmental safety and impact on nearby plants should be considered.
- Application Method: Concentrates and ready-to-use sprays differ in ease and flexibility of application. Foaming granules offer deep and thorough penetration in pipes.
- Environmental Safety: Choose solutions that minimize harm to surrounding trees, plants, and septic system bacteria for sustainable treatment.
- Regulatory Restrictions: Some herbicides may be restricted in certain states. Verify product availability and legal use in your location.
- Frequency of Use: Severe root problems may require recurring treatments to maintain effectiveness. Maintenance formulas help prevent re-growth over time.
- Compatibility with Plumbing: For pipe root killers, ensure the product is non-corrosive and safe for your specific plumbing infrastructure.
Assessing these factors will help you choose the best root killer product tailored to your specific tree root or plumbing challenge, providing efficient results while protecting your environment and investments.
