The Committee received a report which provided an update on trials that took place between May 2022 and October 2022 to explore the alternative to the current weed control practice of using glyphosate to control unwanted vegetation across the borough.

The report explained that the Council remained committed to reducing the use of herbicides across its public estate wherever possible and had over previous years reduced its use considerably. It was noted that the reduction of herbicide complimented the Wildflower Plan to help improve the environment.  However, there was a need to provide effective weed control to protect the carriageways and footpaths in the borough, especially following the Council’s significant capital investment into resurfacing the boroughs residential roads and pavements.

The trial of alternative methods was carried out on Northumberland Avenue, Rabson’s Recreation Ground and Cintra Park.  The alternative methods used were:

1.    Fatty Acid (Pelargonic Acid) spray.

2.    Hot water and steam and manual removal.

3.    Hand removal.

4.    Glyphosate.

5.    Acetic acid Spray.

The results of the trial showed that glyphosate was the most effective and efficient weed control method used. Whilst hot water and steam produced effective results it was unsustainable and not as efficient as the other methods tested.  Hand weeding had the least environmental impact but was not a sustainable option.  Pelargonic and Acetic acid treatments produced quicker results but was less efficient, more costly and required the use of more chemicals.

It was noted that if any new alternatives became available then these would be investigated.  Officers would also consider how other Councils deal with weed control and continue to explore how to reduce the use of glyphosate and increase rewilding of the public realm.

Resolved:

(1)          That the current position on the Trial of Alternative to Glyphosate be noted.

(2)          That the continued controlled us of glyphosate as the most cost effective and efficient method for the control of unwanted vegetation on paved areas and in and around grass verges be approved.

(3)          That any new contract issued include a requirement for the successful bidder to work with the Council to seek a suitable alternative to glyphosate be agreed.

(4)          That the Streetscene Team continue to explore and monitor the ‘Herbicide Market’ for any suitable new alternatives to glyphosate.  The Streetscene Team would also remain vigilant as to how other councils are dealing with the issue be agreed.
