Name That Pesticide How to Identify the Products Your Patients Are Exposed To
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 familyname. More likely they can identify: • BRAND name • TYPE of pesticide (insecticide, herbicide, fungicide, fumigant) • 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
Information Sources on Pesticides • Ingredient statement • EPA registration number • Establishment number • Formulation • Signal word • Statement of practical treatment (first aid) • Personal protective equipment (PPE) handlers • Environmental hazards • Directions for use • Hazards to humans • Storage and disposal directions • Chemical product identification • Physical and chemical properties • Fire and explosion hazards • Toxicological information / Human health data • Regulatory levels and classifications • Personal protection recommendations (concentrate only) • Emergency and first aid procedures • Ecological or environmental hazards • Spills, fires, and accident procedures • Storage and disposal directions Label MSDS
Sample Package Labels • Type of pesticide • Company name • Brand/trade/product name • Common/generic name (sometimes the same as the active ingredients) • Chemical family • Signal word (hazard level)

Class Exercise • Find the following items on the label • Company/Manufacturer’s name • Brand/Product/Trade name • Common name (generic – active ingredient) • Type: use in agriculture • Chemical family • Signal word (hazard level) • Fill in the pesticide classification table (hand out)

Company Name • May be useful in looking up a product • Workers may confuse this name with the brand, product or trade name. • Some companies also produce pharmaceuticals.
Brand/Trade/Product Name • Agricultural workers know pesticides primarily through the brand name • Companies will keep brand names but CHANGE the active ingredients (e.g. Raid) • Can use brand name as a search term
Common Name • Critical identifier of the chemical • Some databases only allow you to search by common name. • Basis of treatment!
Types of Pesticides Disinfectants Fumigants Kill rodents with anticoagulants Control pests by attacking their nervous system Antibiotics for plants Corrosive weed killers
Pesticide Chemical Families-grouping based on similarities- • Similar chemically (similar structure) • Attacks pests in a similar way (toxicity) • Common treatment + antidote Pyrethroid insecticides Organophosphate insecticides Carbamate insecticides Paraquat Diquat herbicides Organochlorine insecticides Chlorophenoxy Herbicides
