The preferred method of product delivery is to use a greenkeeper’s walk-behind boom sprayer or a dosing box where the ACP biocide is pre-mixed to the correct dilution and delivered through a garden hose.
On porous tarmac, Tartan or artificial grass the dilution can increase and the application rate increased in the same proportion. This will contribute toward clearing and maintaining a good drainage system. The frequency of treatment varies year on year and with site exposure. Broadly two treatments each year will maintain a court. Intermediate treatments can be applied on limited areas (under shade for instance).
Moss: Remnants of thallus or small moss balls sometimes remain in cracks & crevices within tarmac after brushing. They will die and wither if the treatment is applied when thoroughly dry.
