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:– Use– Required personal protective equipment

• The label on the bottle or package provides basic information

Company Name

• May be useful in looking up a product

• Workers may confuse this name with the brand, product or trade name.

• Companies will keep brand names but CHANGE the active ingredients (e.g. Raid)

• Can use brand name as a search term

• Critical identifier of the chemical• Some databases only allow you to

search by common name. • Basis of treatment!

LD50

Lethal dose = Amount of chemical it takes to kill 50% of an experimental population


Adapted from Richards, Kerry Penn State University Extension Service
