The weed spraying service was previously undertaken by an external service provider and in 2021 the weed spraying service was brought back in house to be run by LSSL for the first time in 10 years.
This is a seasonal project that operates between the spring (March/April) and autumn (Oct/Nov). Spring is the most effective time for catching weeds in their pre-growth season, in order to prevent them from sprouting. Fall is similarly effective because, ahead of the winter, this is when weeds are most vulnerable.
Staff from across the street cleansing service and refcol services are identified and trained up in the safe use of all aspects of applying and safe handling of chemicals safely, and spraying effectively by way of knap sacks and quad bike application. Tall he quad bikes used are all petrol and not diesel powered engines.
A weed spraying herbicide, containing glyphosate, is applied/sprayed to the leaves of plants to kill both broadleaf plants and grasses. In-line with Liverpool City Councils policy commitment to “phase out” the use of glyphosate prior to 2023 the weed spraying service has immediately reduced concentration of glyphosate as well as an overall 41% reduction in chemical use from previous years. Unlike in previous years, the process involved a Targeted / Controlled Droplet Application (CDA) spray and not blanket spray, which limited the use of glyphosate.
The spraying team is split over both the alleyways and highways with the aim to have as many teams in the field as possible to ensure:
- All 4ft and 9ft alleyways receives 2 sprays
- >2,000km of alleyways were sprayed for weeds by a knapsack on foot
- >4,000km of highways and pavements were attended by either a quadbike or knapsack
