Name That Pesticide
How to Identify the
Products Your Patients
Are Exposed To
Helen Murphy, RN, FNP, MHS
Director of Outreach
Pacific Northwest Agricultural Safety and Health
University of Washington, Seattle WA
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 in the agricultural world = the
package insert for the medical world

Some databases only allow you to search
by common name.
