Ethephon Market is forecast to reach $440 million by 2025, after growing at a CAGR of 9.2% during 2020-2025. Ethephon is a plant growth regulator used to promote fruit ripening, abscission, flower induction, and other responses. Ethephon is registered for use on a number of foods, feed and nonfood crops, greenhouse nursery stock, and outdoor residential ornamental plants, but is used primarily on cotton.

Ethylene the only gaseous plant hormone (C2H4) This is a simple gas that is produced naturally in small quantities by many plant tissues and is able to diffuse readily, via intercellular spaces, throughout the entire plant body. Ethylene is involved primarily in plant responses to environmental stresses such as flooding and drought, and in response to infection, wounding and mechanical pressure. It also influences a wide range of developmental processes, including shoot elongation, flowering, seed germination, fruit ripening and leaf abscission and senescence.

Abscisic acid (ABA) was the last major hormone to be identified, although its existence had been forecast for some time. Groups lead by Addicott studying hormonal relationships in cotton (Ohkuma et al., 1963) And Wareing studying dormancy in woody perennials independently identified Abscisin II in cotton and Dormin in woody plants (Corniforth et al., 1965). The two compounds were ultimately determined to be identical and were given the name Abscisic acid in 1967 at a plant hormone conference in Ottawa, Canada.
