Abstract: A preharvest coating for fruits, vegetables and other plants includes a primary ingredient for protecting the fruit, vegetable or plant from physical harm or damage during growing and harvesting and/or for enhancing the appearance of the fruit, vegetable or plant. In addition, the coating includes a nutraceutical component that may provide health beneficial effects to human consumers of the fruit, vegetable or plant. Such nutraceutical components can include phytonutrients such as flavonoids, stilbenes or other phytochemicals. Preferably, the nutraceutical component is included in an otherwise conventional coating and is applied by means of preharvest thermofogging of the fruit, vegetable or plant.
