1 Name That Pesticide How to Identify the Products Your Patients Are Exposed To

2 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.

3 What the Patient Will Know ? NOT the common or chemical family name. More likely they can identify: BRAND name TYPE of pesticide (insecticide, herbicide, fungicide, fumigant) CROP to which the pesticide was being applied.

4 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

5 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

6 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)

7 Brand Name “SUPRACIDE” Type“Insecticide” Hazard Level “Danger/poison” Poison Icon Common Name “ Methadithion” Manufacturer Gowan Chemical Family “Organophosphate” Antidote “Atropine”

9 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)

12 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.

13 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

14 Common Name Critical identifier of the chemical Some databases only allow you to search by common name. Basis of treatment!

15 Types of Pesticides Types of Pesticides InsecticidesHerbicidesFungicidesRodenticides Disinfectants Fumigants Control pests by attacking their nervous system Corrosive weed killers Antibiotics for plants Kill rodents with anticoagulants

16 Pesticide Chemical Families - grouping based on similarities- 1.Similar chemically (similar structure) 2.Attacks pests in a similar way (toxicity) 3.Common treatment + antidote Organophosphate insecticides Carbamate insecticides Pyrethroid insecticides Organochlorine insecticides Chlorophenoxy Herbicides Paraquat Diquat herbicides

17 How Toxic Is It? Source: Richards, Kerry Penn State University Extension Service


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

20 Source: Richards, Kerry Penn State University Extension Service

21 Adapted from Richards, Kerry Penn State University Extension Service * * DANGER/POISON = extremely toxic by ingestion DANGER = extremely toxic high potential for skin and eye irritation WHO International Standard US Standard

23 Sample Case A patient comes into your office after spilling the weed killer – Direx - on himself. He is having some vague non specific problems. How will you identify what kind of adverse heath effects he may experience?

24 Pesticide Identification Resources Poison Control (800) (TDD) 1(800) Google “ Direx ” Pesticide Websites: – PAN – CDMS – NPIC

25 Practice: Using these resources for Diurex ™ find The common name The chemical family Health effects Recommended decontamination Recommended PPE Describe the attributes of each resource used including advantages and disadvantages
