Abstract:
A method for protection of plants or their crops from infection by insects, comprising:disposing a net of a mesh size allowing adequate ventilation in operative relationship to at least some of said plants and at least partially between said plants and a source of UV light; wherein the net comprises a transparent or translucent polymeric material having incorporated therewith a sufficient amount of UV-light absorbent material to cause at least about 60% of the incident UV light to be filtered out; providing at least one area that would permit said insects to have physical access to said plants; filtering out at least about 60% of the UV light that, except for said net, would have been incident on said plants as a consequence of the UV light absorbent material incorporated with said polymeric material, such that at least about 60% of the incident UV light is prevented from reaching an area around said plants; at least reducing the number of infecting insects passing from said ambient atmosphere to said plants as a consequence of filtering out said UV light; and thereby at least reducing the amount of infection of said plants or crops caused by said insects.
