Documented Uses

• Used in confined areas to extend the life and usefulness of fresh cut flowers, potted plants, and harvested fruits and vegetables; as a plant growth regulator; [HSDB]
• 1-MCP is to be used in confined areas to extend the life and usefulness of fresh cut flowers and potted flowering, bedding, nursery and foliage plants and harvested fruits and vegetable by inhibiting the negative effects of ethylene. ... The use is classified as indoor food and non-food crops application.
• Any of the hormones produced naturally in plants and active in controlling growth and other functions. There are three primary classes: auxins, cytokinins, and gibberellins.
• 1-MCP has a mode of action in plants which is a non-persistent and non-toxic mode of action. 1-MCP prevents the natural chemical, ethylene, from binding to ethylene receptors in plants. This mode of action is not relevant in animals, since ethylene receptors are not present in animal tissues.
