However it has become apparent that this treatment has been ineffective in some areas, and following correspondence and consultation with members of the public and councillors the authority has been in discussions with the contractor about how best to tackle this. As a result a renewed spraying campaign with particular attention to problem areas has been agreed.
Councillor Alan Spinks, executive member for the environment, said today: 'We are grateful to all the residents who contacted us about this problem. We always welcome this kind of communication as it helps us understand the needs of the community.
'In this instance, I and other members have also been acutely aware of the increase in weed growth on public highways and have therefore instigated an action plan with our contractors.
'From our point of view we have many projects running throughout the city - from those involving regeneration to the Bright and Clean battle against litter - and it is not acceptable that the environment is marred and safety is put at risk by this overgrowth, which is why we have taken these measures.'
