Description and Uses
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.
Accelerates the preharvest ripening of fruits and vegetables.
