Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "эфир" (ether/ester), which is a different class of compound.
- Do not associate with the English prefix "eth-" relating to ethics or ethnicity.
- The closest direct translation is the technical loanword "этион".
Common Mistakes
- Misspelling as 'ethian', 'ethyon', or 'etheon'.
- Mispronouncing the 'th' as in 'thin' (/θ/) instead of as in 'the' (/ð/) or, more accurately for this word, as a simple /t/ sound preceding the /iː/.
- Using it as a general term for any pesticide.

FAQ
Frequently Asked Questions
Ethion is an organophosphate insecticide which is toxic to humans. Its use is highly regulated, and safety protocols including protective equipment and pre-harvest intervals must be strictly followed to minimise risk.
Historically, it has been used on a range of crops including citrus fruits, apples, pears, nuts, and some vegetables. Approved uses vary significantly by country and change over time as regulations evolve.
The primary concerns are its toxicity to non-target organisms, including beneficial insects, aquatic life, and birds, as well as its potential to persist in soil and water under certain conditions.
As an organophosphate, it works by inhibiting the enzyme acetylcholinesterase, leading to a nervous system breakdown in insects. This distinguishes it from other classes like pyrethroids (neurotoxins) or neonicotinoids (acting on nicotinic receptors).
