A concentrated green pigment product used for applying to turfgrass surfaces, helping to provide a longer lasting green appearance. It does however contain a chemical (1,2-benzisothiazol-3(2H)-one) which is classed as being ‘Very toxic to aquatic life', so it is important to ensure an adequate vegetative buffer zone, of 3m-5m, is provided when applying near to water courses. It is manufactured by Syngenta.
