Nationwide FAST System treatment, monitoring and long‑term Japanese Knotweed control for residential, commercial and development sites.
Specialists in Advanced Herbicide Translocation & Long‑Term Knotweed Control
The IVM FAST System is our proprietary herbicide treatment method, engineered in‑house to maximise herbicide translocation into Japanese Knotweed rhizomes. By combining the latest herbicides with specialist wetters and adjuvants, the FAST System delivers predictable, long‑term suppression and full mortgage‑compliant control. If you're unsure whether the plant on your land is Knotweed, our guide to Knotweed Lookalikes can help you confirm before taking action.
Nearly Two Decades of Innovation in Knotweed Treatment
Since 2007, IVM has refined the FAST System through extensive field testing, product development and performance monitoring across thousands of UK sites. Our team supports homeowners, surveyors, developers and commercial clients with a treatment method proven to outperform standard herbicide programmes. If you’ve just discovered Knotweed and aren’t sure what to do next, our guide on What To Do If You Have Knotweed provides a clear step‑by‑step overview.

The FAST System was created to solve the limitations of standard herbicide programmes. It is the most effective method of managing Japanese Knotweed when:
• High herbicide translocation into rhizomes is essential
• Long‑term suppression is required for mortgage or development compliance
• Standard spraying alone is unlikely to achieve predictable results
• Sensitive sites require controlled, low‑drift application
• A structured, engineered treatment method is preferred over generic programmes
The IVM ‘FAST’ System (Foliage And Stem Treatment)
Developed exclusively by IVM, the FAST System combines advanced herbicides with specialist wetters and adjuvants to maximise penetration and translocation. Staged applications, seasonal timing and targeted follow‑up ensure consistent, long‑term suppression.
Stem Injection
Used where precision is essential, stem injection delivers herbicide directly into the plant’s vascular system. This method is integrated into the FAST System for sensitive or high‑value sites.
Optimised Foliar Application
Controlled foliar application during peak growth ensures maximum uptake. When combined with FAST System chemistry, this significantly increases downward translocation into the rhizomes.
All FAST System treatment programmes include:
• PCA‑compliant Knotweed Management Plans
• Staged treatment schedules and seasonal timing
• Monitoring reports and photographic evidence
• Site plans and treatment maps
• 10‑year guarantees (insurance‑backed options available)
