Abstract
Plant material such as tobacco is protected during storage by enveloping the plant material in a thin film that is composed of a polymeric material and isopropyl-(E,E)-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate (hereinafter referred to as "methoprene"). Air moves within the envelope carrying methoprene that has migrated from the surface of the film to the surface of the plant material. The thin film is a biaxially oriented polyolefin that has a thickness of from 0.01 to 0.2 mm and has from about 100 to 20,000 ppm of said methoprene incorporated therein.
