Moss & Algae are primitive plants which can survive in damp and shaded environments, they are a concern as they can make the surface extremely slippery which is highly undesirable in safety conscious industrial situations. They are most prevalent in autumn and spring when moss and algae have ideal moisture and temperature conditions.
The problem is best tackled using integrated weed control combining chemical applications with increased sweeping regimes. The long term solution is to alter the local environment to make it less suitable to algae and moss by reducing the shade and moisture whilst increasing air movement.
