Abstract: Solutions and methods for forming an exogenous flexible film on a plant and plants including the exogenous flexible film. The solutions include a solvent, a film forming matrix component, a hydrophobic barrier component, a plasticizing component, and a film enhancing component. The methods include spraying the solution on the plant. The methods also include evaporating at least a fraction of the solvent from the solution to form the exogenous flexible film. The plant includes fruit, and the spraying includes spraying at least 45 days prior to harvesting the fruit. The plants include an exogenous flexible film formed from the solutions and/or by the methods.
