Weed control

About the weed treatment process and how weeds alongside roads are treated and managed in your area.

We treat all kerb lines adjacent to carriageways and within the road channels (adjacent to the kerb). Treatment is also carried out to the back of a footpath where a building or wall is present however, we do not treat the weeds if the back of the footway is a verge.

Is the weed treatment solution harmful to humans or animals?

The solution we use is called Monsanto Amenity Glyphosate systemic. The solution is not harmful to humans or animals however, we would advise not having contact with the solution until it is fully dry.

How long does the solution take to work?

Once the weeds have been treated with the above solution, it will take approximately 2 weeks for the solution to take effect on the weeds and roots. 

This is weather dependant and needs dry weather to be effective. If it rains within 6 hours of application being applied, this could affect the strength of the solution and the area would require a further treatment. We monitor the forecast and apply the solution when there is a low chance of rain. We may delay treatment if rain or windy conditions are forecast.

How often do you treat the weeds?

Across the county, we undertake two treatments per year. This will commence after the emergence of the spring weed flush.

Why have you not treated the weeds at the times your programme said you would?
