In this edition, we focus on the use of herbicide as a control for Japanese knotweed on development sites. Our feature explores the potential pitfalls of opting for herbicide treatment as a low-cost control method. Developers often face the dilemma of choosing between herbicide treatment and removal, and our comprehensive analysis sheds light on the benefits and risks associated with each approach.
Drawing upon a recent case study, we uncover the challenges developers face when choosing herbicide treatment, including the risk of knotweed regrowth due to unexpected site changes. Moreover, we discuss the legal implications developers may face if knotweed regrows post-remediation, and why excavation is often recommended as the best on-site solution.
