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 ?
NOT the common or chemical family name. More
likely they can identify:
the BRAND name
 the TYPE (insecticide, herbicide,
fungicide, fumigant)
 the CROP to which the pesticide was
being applied.

Pesticide Product Label


The label is the agriculture world = the
package insert for the medical world
The label is the LAW and dictates:




Required personal protective equipment

provides basic information
