The present disclosure provides an agricultural barrier comprising a polymeric material having a plurality of openings, said polymeric material comprising: (a) at least one thermoplastic polymer, and (b) non-doped nanoparticles comprising one or more metal oxides. In one embodiment, the metal oxide is titanium oxide. In some further embodiments, the nanoparicles consist of titanium oxide.The agricultural barrier may be used for constructing agricultural housings for cultivation of a variety of crops. The present disclosure also concerns a method for manufacturing the barrier, the method comprising mixing a combination of at least one thermoplastic polymer and the nanoparticles, under condition which cause the combination to form into a melt and processing said melt into a polymeric material having a plurality of openings.
