Maximizing Your SmartFresh℠ Investments

By: Michael Parker, Steve McArtney, Robert Tom Hoyt, J.D. Obermiller Horticulture Information Leaflets

SmartFresh℠ (1-methylcyclopropene, MCP) is a relatively new tool for postharvest management of apples. In 2002, SmartFresh was approved for commercial use on apples by the Environmental Protection Agency under a reduced risk program because of the very low toxicity of the product and the fact that treated fruit have no detectable residue. It is thought to bind irreversibly to the ethylene receptors in plant tissues making the crops insensitive to ethylene and subsequently retarding many of the ethylene mediated responses such as fruit softening in apples. SmartFresh can maintain apple firmness and acidity and decrease scald and greasiness even when stored under less than ideal storage temperatures.
