| Chemical Properties | white to beige powder |
| Chemical Properties | Ethephon is a white to tan powder. Commercialproduct is a white, waxy solid. Commercial products may beavailable as aqueous solutions or soluble concentrates. |
| Uses | 2-Chloroethyl)phosphonic acid (Ethephon) is the most widely used plant growth regulator. Ethephon is often used on wheat, coffee, tobacco, cotton, and rice in order to help the plant's fruit reach maturity more quickly. The toxicity of Ethephon is actually very low, and any Ethephon used on the plant is converted very quickly to ethylene. |
| Uses | Accelerates the preharvest ripening of fruits and vegetables. |
| Definition | ChEBI: A phosphonic acid compound having a 2-chloroethyl substituent attached to the P-atom. |
| Agricultural Uses | Plant growth regulator: Ethephon is a plant growth regulator used to promotefruit ripening, abscission, flower induction, and other responses.It is registered for use on a number of food, feedand nonfood crops (rubber plants, flax), greenhouse nurserystock, and outdoor residential ornamental plants, but is usedprimarily on cotton. Ethephon is applied to plant foliage byeither ground or aerial equipment. It also may be appliedby hand sprayer to certain home garden vegetables and ornamentals.Use practice limitations include prohibitionsagainst applying ethephon through any type of irrigation system;feeding or grazing livestock in treated areas; and treatingwithin 2 to 60 days of harvest, depending on the crop. |

| Safety Profile | Moderately toxic by ingestion. Mddly toxic by skin contact. A plant growth regulator. Caution: Spray formulations are quite acidic, about pH 1 .O. May be irritating to exposed skin and eyes, or if inhaled. When heated to decomposition it emits toxic fumes of Cland POx. |
| Potential Exposure | Ethephon is an organophosphonateplant growth regulator used to promote fruit ripening,abscission, flower induction, and other responses. It is registered for use on a number of food, animal feed and nonfoodcrops (rubber plants, flax), greenhouse nursery stock, andoutdoor residential ornamental plants, but is used primarilyon cotton. Ethephon is applied to plant foliage by eitherground or aerial equipment. It also may be applied by handsprayer to certain home garden vegetables and ornamentals.Use practice limitations include prohibitions against applying ethephon through any type of irrigation system; feedingor grazing livestock in treated areas; and treating within2 to 60 days of harvest, depending on the crop |
| Environmental Fate | Soil. Degrades rapidly in soil to phosphoric acid, ethylene and chloride ions (Hartleyand Kidd, 1987) and naturally occurring substances (Humburg et al., 1989). Chemical/Physical. In an aqueous solution at pH 3.5, ethepon begins to hydrolyze,releasing ethylene (Windholz et al., 1983). |
| Shipping | UN2928 Toxic solids, corrosive, organic, n.o.s.,Hazard Class: 6.1; Labels: 6.1-Poisonous materials,8-Corrosive material, Technical Name Required |
| Incompatibilities | Hygroscopic. Aqueous solutions arehighly acidic. May cause corrosion if metals, especiallywhen moisture is present. Contact with flammable materialmay cause fire and explosions. Contact with combustible oroxidizable materials may form heat-, shock-, and frictionsensitive explosive mixtures. Static electricity may alsocause explosions. Keep away from all acids, especiallydibasic organic acids, ammonium compounds, antimonysulfide, arsenic trioxide, metal sulfides, powdered metals,calcium aluminum hydride, cyanides, manganese dioxide,phosphorus, selenium, sulfur, thiocyanates, and zinc. |
| Waste Disposal | Destruction by alkali hydrolysis or incineration. Containers must be disposed of properlyby following package label directions or by contacting yourlocal or federal environmental control agency, or by contacting your regional EPA office. |
