Herbicide, Stanmore

A herbicide treatment plan was put in place to treat Japanese knotweed which was discovered on site. The client did not have any plans to develop, so this was the most cost effective method for them.


The client initially instructed Environet to carry out herbicide foliar spray on one area. Further instructions came in 2012, 2013 and 2014 for further areas on site. In total our client had 18 stands of established Japanese knotweed.

4 herbicide applications were administered over the growing season, and the site was monitored for any regrowth.  The client was able to continue with day to day use of the site, safe in the knowledge that the knotweed problem had been controlled.
