Tordon RTU Specialty Herbicide
Tordon RTU is a specialty herbicide designed to kill woody plants and trees through cut-surface treatments in non-cropland areas and along fence lines or rights-of-way. It translocates into the root system, halting resprouts and keeping more than 20 woody species at bay. This product is intended for professional or experienced users who require targeted control of unwanted woody growth in areas where trees or brush interfere with access, sightlines, or maintenance operations. Regulatory restrictions may apply in certain regions.
Ready-to-use Stump Stop

It is designed for versatile use in forests, permanent pastures, and along roadsides or fence lines. The product supports effective vegetation management in hard-to-reach or remote locations and can be applied with various equipment to target stumps and adjacent regrowth. Its ready-to-use nature makes it suitable for fieldwork and site-wide vegetation control programs.
Stump-Out Stump & Vine Killer
Stump-Out is a concentrate designed for woody plant and vine control, with options to use as a stump killer or as a foliar spray. This flexibility makes it suitable for treating stumps, preventing sprouting, and managing multi-year regrowth on vines or similar woody species. The product is applicable in residential, agricultural, and roadside settings, enabling targeted control where undesirable woody growth persists after cuttings or in fence lines and other clearings.
Buying Guide: Moss and Tree-Related Vegetation Control
- Target and area: Determine whether the problem is surface moss on roofs or patios, lawn moss in turf, or woody vegetation (stumps, vines, or saplings). Some products are designed for quick surface treatment, while others aim at root systems and regrowth.
- Application method: Hose-end sprayers offer speed for large surfaces, while granular or ready-to-use liquids may provide more precise local control. Consider your equipment and comfort with applying chemicals.
- Impact on desirable plants: Some moss killers and stump treatments can affect nearby grasses, shrubs, or crops. Read label directions for compatibility with existing landscaping and any necessary buffer zones.
- Regulatory and region considerations: Certain products have regional restrictions or usage limitations. Check local regulations before purchase and follow label instructions.
- Longevity and resprouting: If regrowth is a concern, choose products with residual control or those that impede resprouts in woody species. Some solutions target roots to reduce future growth.
- Environmental considerations: Prefer products with minimal impact on soil health and water systems when used as directed. Foaming or systemic formulas may behave differently in soil and pipes.
- Safety and handling: Some items require protective equipment or careful handling around children and pets. Use as directed and store appropriately.
- Budget and frequency: Consider the frequency of application, coverage area, and overall cost per treatment. Ready-to-use formats reduce preparation time but may have higher per-area costs.
