Abstract
The present invention relates to compositions for protecting plants, including, for example, fruits, vegetables, plants and flowers, against decay, and methods of making the compositions. A composition according to the invention includes a substrate coated with an adhesive layer, the surface of the adhesive layer covered with a film comprising a powder mixture that includes at least one substance capable of adsorbing ethylene released by the plant, and at least one substance, an oxidizing agent, capable of degrading ethylene. In order to reduce the quantity of powder needed to protect plants, the powder mixture is in the form of individualized grains existing as a film at surface of the adhesive layer. Part of the grain surface remains outside of the adhesive layer, thereby making the grain active toward the degradation of ethylene.
