Abstract: Compositions and methods for extending the shelf life, quality and performance of plants under moisture stress. The compositions include an antioxidant and an osmolyte dissolved in water. The compositions can be prepared from a dry or liquid concentrate. When prepared from a liquid concentrate, the compositions also preferably include a wetting agent, an emulsifier a preservative and a colorant. In a preferred method of the invention, the compositions are formulated for application via sub-irrigation, drench and/or drip, or are formulated for application via overhead. The compositions maximize water saturation ability (container capacity), and provide better water retention and better rewetting ability. The compositions also improve water usage efficiency and reduce watering frequency requirements. These affects last multiple watering cycles, thereby providing product efficacy.
