Class 1
Assess Your Pesticide Use
• Instructor Introduction
• Class member introductions
Welcome/Introductions
Logistics/Announcements
• Overview of the Urban Pesticide Reduction Program (UPRP)
• Effects of Pesticides on Human and Environmental Health
• What is a Pesticide?
Today’s Agenda
• Overview of the Urban Pesticide Reduction Program (UPRP)
• Effects of Pesticides on Human and Environmental Health
• What is a Pesticide?
Today’s Agenda
• USA: 74-90% of households utilize pesticides on an annual basis (Whitmore et al. 1994; Landrigran et al. 1999, Fishel 2007)
• Oregon: 46% of households used pesticides in 2007 (PURS 2008)
• Portland Metro: 29% of households used lawn and garden pesticides and 17% used indoor pesticides (Peters et al. 2007)
Pesticide Use Statistics
• Pesticide use is generally underreported, and risk perception is generally underestimated (Nieuwenhuijse et al. 2005)
• PURS (Oregon’s Pesticide Use Reporting System)• Survey “participants were unable to determine what
products were pesticides”• “continued concerns about the ability of pesticide
users to read the label and correctly identify information”
• “Moss control products accounted for 47% of the pounds of active ingredient, but only 2% of the reports identified moss control as the purpose”
Do We Really Use Fewer Pesticides?
Which of these is NOT a pesticide?
• Reduce pesticide use in residential areas – both inside and outside of home.
• Increase knowledge about pesticides.• Safe pesticide use• Alternatives to pesticides
UPRP Goal
• Three classes
• Class 1: Overview of UPRP. Pesticides, defined. Assess your pesticide use in the home, garden and lawn.
• Class 2: Reading a pesticide label. Proper use, storage and disposal of pesticides.
• Class 3: Environmental fate of pesticides. Alternatives to pesticides for pest management. Prevention rather than reaction.
Urban Pesticide Reduction Program (UPRP)
• Does this program work? Does this program decrease pesticide use and increase knowledge?
• Voluntary, anonymous surveys• Pre-tests • Post-test • Follow-Up (6 months following classes)
• IRB Approved (Institutional Review Board)

Sign-In Sheet
• Take 3-5 minutes to think about your pesticide use over the last 12 months.
• On a piece of paper:
list all of the pesticides that you have usedOR
list all of the pests for which you have used products
Opening Exercise
• Overview of the Urban Pesticide Reduction Program (UPRP)
• Effects of Pesticides on Environmental and Human Health
• What is a Pesticide?
Today’s Agenda
• A 2000-2005 U.S. Geological Survey (USGS) study found a variety of pesticides in the lower Clackamas River mainstem and tributaries, along with trace-level detections of pesticides in treated drinking-water samples.
• A total of 63 pesticide compounds were detected.
• The herbicides atrazine and simazine were the most common, detected in half of the samples.
• High-use herbicides such as glyphosate and triclopyr/2,4-D-the active ingredients in RoundUPTM and CrossbowTM, respectively-also were frequently detected. ..."
• The full press release may be viewed at: http://www.usgs.gov/newsroom/article.asp?ID=1895
• The full report may be found at: http://pubs.usgs.gov/sir/2008/5027/
Pesticides in Clackamas
March 18, 2008 Press release, USGS
Common Herbicide Causes Inflammation in FishNo Herbicide160X magnification, Fish Gills
5 mg Glyphosate / Liter Water160 Magnification, Fish Gills
Signs of inflammation
• Colony Collapse Disorder: worker bees in honey bee hives abruptly disappear
• Pesticides may be a contributing factor. Until scientists know more, it is best to use pesticides with caution.
Pesticide Effects on Bees
CCD Hive
Healthy Hive
• Organophosphates: commonly sold, broad spectrum, contact insecticide
• Will kill ladybugs, lacewings, bees, spiders, flower flies and other beneficial insects.
Common Pesticides Impact Beneficial Insects
• Cholinesterase is present in many organisms, including all mammals (like humans!)
• Cholinesterase is an enzyme that is ubiquitous in the human body
• Cholinesterase is critical for many nervous system functions
Common Pesticides Impact Human Health
• Organophosphates • Irreversibly inhibits cholinesterase that is
present in the human body• Cholinesterase must be replaced, by the body,
after exposure to an organophosphate pesticide
• Carbamates • Temporarily inhibits cholinesterase that is
present in the body • Effects can be rapidly reversed (time required
depends on level of exposure)
Pesticides That Inhibit Cholinesterase
• Negative effects of pesticides are amplified when pesticides are:• Misused• Overused• Used at an inappropriate time• Incorrectly stored• Incorrectly disposed
Pesticide Mis-Use
• Overview of the Urban Pesticide Reduction Program (UPRP)
• Effects of Pesticides on Human and Environmental Health
• What is a Pesticide?
Today’s Agenda
• A pesticide is any substance intended tocontrol, destroy, repel, or attract a pest.
What is a pesticide?
• We determine what is a pest.• Causes damage or economic loss• Transmits or produces disease
• Pests can be animals (including insects).• Pests can be unwanted plants.• Pests can be microbes.
What is a pest?
• Is an EPA registration number on the container?
• If so, it is a pesticide.
How do I know if it is a pesticide?
EPA Reg. No. 3120-280
Identifies manufacturer
Identifies product
• Toothpaste, mouthwash (regulated by FDA and not EPA)
• Fertilizers (except for weed and feed products)
• Compost tea• Beneficial insects that eat insect pests
• Ladybugs, Lacewings, Preying Mantis, etc.• Parasitoid wasps• Nematodes
• Bt and spinosad are microrganisms that ARE pesticides
What is not a pesticide?
• Do not have an EPA Registration Number• Are deemed ‘demonstrably safe’
• A complete list of Minimum Risk Pesticides can be viewed at: http://www.epa.gov/oppbppd1/biopesticides/regtools/25b_list.htm
Minimum Risk Pesticides
Citronella White pepper
Castor oil Egg whites and egg solids
Cinnamon oil Citric acid
Clove oil Rosemary oil
Dried Blood Thyme oil
Mint oil Corn gluten meal
• Please take 10 minutes to complete the survey.
• We will revisit the different parts of the survey throughout the UPRP.
Pesticide Use Self-Assessment
• Was there a difference between your original narrative, and the checklist audit of your pesticide use?
Pesticide Use Results
• Please bring a pesticide from home.
• We will be using this pesticide for an activity focused on reading labels.
• We will also discuss safe use, storage and disposal of pesticides, as well as the use of personal protective equipment.
