Our previous research has shown wavelength selective plastic (SRM-olive) coupled with a row cover has given consistent top early yields. Clear plastic mulch was also superior provided there was excellent weed control. Agribon is a polypropylene spunbond material available in several weights that give various light transmission and frost protection characteristics. It is mostly used as a floating row cover for extended season production, frost protection, and wind and insect control. We tested the traditional slitted clear plastic row cover against the agribon (AG-19, light weight at 0.55 oz/yd2 with 85% light transmission).
