A crop netting, crop cover or ground cover material which is knitted woven, or non-woven, from a synthetic monofilament, multifilament yarn or tape or a combination comprises comprising at least one pigment such that the monofilament, multifilament yarn, or tape: across a UV wavelength range about 300 to about 380 nm: absorbs at least about 55% solar radiation on average and transmits less than about 30% solar radiation on average； across a visible wavelength range about 420 to about 700 nm: transmits at least about 10% solar radiation on average and reflects at least about 10% of solar radiation on average； across an infrared wavelength range about 700 to about 1000 nm: transmits between about 15% and about 80% of solar radiation on average across an infrared wavelength range of 1500 to 1600 nm: transmits at least about 15% to about 90% solar radiation on average； across an infrared wavelength range about 700 to about 1000 nm: transmits not more than about 9 percentage points on average more than and transmits not less than about 9 percentage points on average less than the solar radiation transmission across said visible wavelength range about 420 to about 20 700 nm； and across an infrared wavelength range about 1500 to about 1600 nm: transmits not more than about 9 percentage points all average more than, and transmits not less than about 9 percentage points on average less than the solar radiation transmission across said infrared wavelength range about 700 to about 1000 nm.
