Documented Uses

Used as plant growth regulator to promote ripening in fruits, nuts, and other crops and to stimulate latex flow in rubber; [HSDB] Used primarily on cotton; [Reference #1]
A plant-growth regulator that increases rate of ripening of plants by promoting release of ethylene, stimulates rubber latex formation; ripening of sugarcane; flowering agent for pineapple; color enhancer.
In cotton, it is used as a boll opener and defoliant prior to harvesting.
Ethephon is used to promote fruit ripening, abscission, flower induction, breaking of apical dominance (inhibition of the growth of lateral buds by the terminal bud of a shoot), and other plant responses.
CLEAVAGE OF THE BIS(2-CHLOROETHYL) ESTER OF 2-CHLOROETHYL PHOSPHONIC ACID
Ethephon is made from tris(2-chloroethyl) phosphite by rearrangement to bis(2-chloroethyl)2-chloroethyl phosphonate followed by hydrolysis
