Disclosed is a reflective netting material wherein a monofilament of the netting comprises polyethylene with a white pigment such as calcium carbonate in an amount of about 14%, wherein the netting is a knitted, woven, or non-woven structure, from a synthetic monofilament, yarn, or tape or combination thereof, wherein the pigment is selected to provide the netting which reflects at least 30% solar radiation on average across the UV (wavelength about 280-400 nm), visible (wavelength about 400-700 nm) and very near infrared ( wavelength about 700-800 nm) ranges, and which transmits at least 10% on average of solar radiation across the wavelength range about 800-2500nm, and wherein the netting is for placement in an elevated position above the ground and over fruit- or vegetable-bearing plants, such that it can create a plant environment beneath the material which is favourable for the growth of said plants and/or the development of fruit or vegetables borne by the plants, by virtue of diffusion of incident radiation including UV radiation by the netting material. The netting preferably has a cover factor (as herein defined) of less than 90%. |
