Method to Put Environmental Price of Pesticides
1) New Jobs2) New Businesses3) Reduced Agricultural Production Costs4) Development of New Products5) Decrease in Pounds of Pesticide Use 6) Decrease Numbers of Pesticide Apps7) Lower Environ. Impacts of Pesticide Use8) Development of New and/or Improved
Pesticide Application Technology
Indicators of IPM Success We Have Used
9) Increased Communication/Partnership (Processors, Producers, and Retailers)10) Increases in Federal or State Funding11) Reduced no. of pesticide treated acres12) Shift in reliance to less-toxic pesticides 13) Creation of more IPM Options14) Biocontrol projects funded then and now 15) Changes in Producer IPM Knowledge, Opinions, Skills, and Aspirations
Indicators of IPM Success We Have Used
One recommendation:
"a related management shortcoming of the federal IPM initiative is that USDA has not devised a method for measuring the environmental or economic results of IPM implementation."
US General Accounting Office - 2001

13 Criteria Used
• Dermal Toxicity• Chronic Toxicity - Reproductive - Teratogenic - Mutagenic - Oncogenic • Fish Toxicity
• Bird Toxicity• Bee Toxicity• Beneficial Arthro.• Soil Persistence• Leaf Persistence• Runoff Potential• Leaching Potential
Over 200 pesticides evaluated(insecticides, fungicides, herbicide)
http://www.nysipm.cornell.edu/publications/EIQ.html
CHRONIC POTENTIAL(Reproductive, Teratogenic,
Mutagenic, Oncogenic)
Little or none = 1
Potential = 3
Definite = 5
http://www.nysipm.cornell.edu/publications/EIQ.html
EIQ Equation
EIQ =
{[C(DT*5)+(DT*P)]+
[(C*(S+P)/2*SY)+(L)]+
[(F*R)+(D*((S+P)/2)*3)+(Z*P*3)+(B*P*5)]}/3

If more biological/cultural control practices are used than less pesticides will be used
If better scouting or forecasting methods are implemented than less pesticides used
Ultimately, changes in IPM adoption behavior leads directly to changes in pesticide use patterns
Methods of Measuring IPM Adoption
Goal:
To develop a “common currency” to assess the environmental andeconomic impact of IPM programs that can be easily communicated.
Pesticide Price Model
Price = Raw materials
+ Capital
+ Production + Transportation
+ Profit
(+ Environmental Cost)
Greener is Cheaper
Pesticide Price Method
3 Components needed
1) Total environmental cost of pesticides used
2) Environmental risk rating for each pesticide
3) Total amount of pesticide used
Pesticide Price Method
Pimentel et al. (1992) estimated the social and environmental cost of pesticide use in the US to be $ 8.1 billion dollars.
Gianessi and Anderson (1995) estimated that 732 million pounds of ai of pesticides were used in the US in 1992.
Environmental cost = $ 8.1 billion / 732 mil lbs. $11.06 per pound of active ingredient of pesticide
How do you incorporate a fair environmental cost per pesticide?
If a pesticide is a leacher it should a have higher groundwater costs
If a pesticide kills bees it should have higher bee costs
Each pesticide should have a different cost for each environmental impact category

• Used (94%) of Pimentel cost calculation (GW = $1.8M)
• Determined relative environmental impacts of each chemical for each category (modified EIQ’s - 1,10,100 - used Field Use EIQ)
•Calculated average cost/FUEIQ
• Determine $/lb ai

Behavior Changes & IPM Implementation
• Negative IncentivesPesticide taxes
• Positive IncentivesIPM MarketingTrading Pesticide Credits
Study on Pesticide Reduction Incentives in Denmark
• subsidies of environmentally favorable practices are inefficient
• “polluter pays” taxes are best
- for a 40-45% reduction in pesticide use, cost should increase by 120%
Dubgaard 1991
Atrazine Environmental Price
Price of Atrazine 4L = $1.81/ lb
Environmental Price = $10.72/ lb ai 43% ai = $ 4.61

Summary
The Pesticide Price Method
• can be used to discuss stewardship issues with growers, policy makers, and the general public
• is one method to make comparison between commodities and growing practices
• can be used to measure IPM adoption rates using either positive or negative incentives
