The nomenclature of pesticides is similar to
medications in that they have.

• A brand/trade or product name e.g. Motrin
• A generic name (common name or active
  ingredient) ibuprofen
• A chemical family e.g. NSAID

Likewise one needs to know the chemical family
and more specifically the common name to
understand the health effect of an exposure and
how to treatment a poisoning.

What the Patient Will Know ?

  likely they can identify

  fumigant)
• the CROP to which the pesticide was being
  applied.
