You might recognize the first as one of the substances found in oat products (alongside glyphosate) that caused a health scare in 2019. It makes sense that people might be worried because organophosphate is essentially a neurotoxin; in insects, it causes paralysis by inhibiting an important enzyme.
Pyrethroids act similarly by causing mobility issues, weakness, and eventual death. Carbamates, as you can probably guess, also works on the nervous system inducing paralysis and respiratory failure. If I…
