The present invention relates to ground cover sheet materials and netting materials, and to ground cover sheets and netting comprising such materials. The materials comprise a green pigment derived from one or more pigments, and at least one additional pigment which does not significantly decrease the amount of solar radiation transmitted by the polymer-pigment mixture in the range of about 700nm – 2500nm, and/or at least one additional pigment which decreases the amount of solar radiation transmitted by the material in the blue light range of about 440nm – 490 nm and in the red light range of about 620-700 nm. |
