| Hazard Information | Back Directory | [Potential Exposure]
Ethephon is an organophosphonate
plant 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 nonfood
crops (rubber plants, flax), greenhouse nursery stock, and
outdoor residential ornamental plants, but is used primarily
on cotton. Ethephon is applied to plant foliage by either
ground or aerial equipment. It also may be applied by hand
sprayer to certain home garden vegetables and ornamentals.
Use practice limitations include prohibitions against applying ethephon through any type of irrigation system; feeding
or grazing livestock in treated areas; and treating within
2 to 60 days of harvest, depending on the crop | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way valve
or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance,
immediately flush skin or eyes with running water for at
least 20 minutes. For minor skin contact, avoid spreading
material on unaffected skin. Keep victim warm and quiet.
Effects of exposure (inhalation, ingestion or skin contact) to
substance may be delayed. Ensure that medical personnel
are aware of the material(s) involved and take precautions to
protect themselves. Medical observation is recommended for
24 to 48 hours after breathing overexposure, as pulmonary
edema may be delayed. As first aid for pulmonary edema, a
doctor or authorized paramedic may consider administering
a drug or other inhalation therapy. Cigarette smoking may
exacerbate pulmonary injury and should be discouraged for
at least 72 hours following exposure | [Shipping]

Hygroscopic. Aqueous solutions are
highly acidic. May cause corrosion if metals, especially
when moisture is present. Contact with flammable material
may cause fire and explosions. Contact with combustible or
oxidizable materials may form heat-, shock-, and frictionsensitive explosive mixtures. Static electricity may also
cause explosions. Keep away from all acids, especially
dibasic organic acids, ammonium compounds, antimony
sulfide, arsenic trioxide, metal sulfides, powdered metals,
calcium aluminum hydride, cyanides, manganese dioxide,
phosphorus, selenium, sulfur, thiocyanates, and zinc.
| [Description]
Ethephon, which is also known as chlorethephon and 2-CEPA, is a plant growth regulator which is approved for use in the UK and the EU. It is highly soluble in water and many organic solvents. It is not considered persistent in soils but can be in water bodies under certain conditions. Based on its physico-chemical parameters, ethephon is not expected to leach to groundwater. It’s ecotoxicity is considered low to moderate for most species. There are concerns regarding its toxicity to humans being moderately toxic via the oral route, an acetyl cholinesterase inhibitor, neurotoxin and irritant. | [Chemical Properties]
Ethephon is a white to tan powder. Commercial
product is a white, waxy solid. Commercial products may be
available as aqueous solutions or soluble concentrates. | [Chemical Properties]
white to beige powder | [Waste Disposal]
Destruction by alkali hydrolysis or incineration. Containers must be disposed of properly
by following package label directions or by contacting your
local or federal environmental control agency, or by contacting your regional EPA office. | [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 mat
urity 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. | [Uses]
Plant growth regulator. | [Definition]
ChEBI: A phosphonic acid compound having a 2-chloroethyl substituent attached to the P-atom. | [Production Methods]
Ethephon is commercially produced by synthesising 2-chloroethylphosphonic acid, an organophosphorus compound. The process typically involves reacting phosphorus trichloride with ethylene oxide or similar intermediates under controlled conditions to form the active molecule | [Agricultural Uses]
Plant growth regulator: Ethephon is a plant growth regulator used to promote
fruit ripening, abscission, flower induction, and other responses.

Soil. Degrades rapidly in soil to phosphoric acid, ethylene and chloride ions (Hartley
and 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). | [Pesticide Type]
