• Uses: 1-Methylcyclopropene (1-MCP) is a plant growth and ripening regulator. It acts as an inhibitor of ethylene by blocking the receptor of ethylene in the tissues of plants, flowers, fruit and vegetables, thus preventing the ripening process. It is used to inhibit ethylene production in cut flowers, potted flowers, bedding, nursery and foliage plants, and in stored fruits and vegetables. It is approved for use only in enclosed spaces, such as greenhouses, store rooms, coolers, enclosed truck trailers, controlled atmosphere food storage facilities, and shipping containers.
