(2-Chloroethyl)phosphonic acid, widely known as Ethephon, stands as one of the most commonly applied plant growth regulators globally. It is frequently utilized on crops including wheat, coffee, tobacco, cotton, and rice to accelerate the ripening process of fruits and enhance maturation speed. Ethephon features low acute toxicity, and residues on treated plants break down rapidly into ethylene.

Product Application of Ethephon 16672-87-0
As a versatile plant growth regulator, Ethephon supports fruit ripening, organ abscission, flower promotion, and multiple physiological responses. It is registered for application on food crops, feed crops, non‑food crops like rubber and flax, greenhouse plants, and outdoor ornamental plants. Cotton remains its primary target crop.
Application methods include ground and aerial spraying on foliage; home garden uses may employ manual sprayers for vegetables and ornamentals. Restrictions apply to irrigation system application, livestock grazing in treated zones, and pre‑harvest intervals ranging from 2 to 60 days based on specific crop requirements.
