IPM Measurement Putting an Environmental Price To Pesticide Use Joe Kovach IPM Program Ohio State University
Method to Put Environmental Price of Pesticides • Background • Method • Application
Indicators of IPM Success We Have Used • 1) New Jobs • 2) New Businesses • 3) Reduced Agricultural Production Costs • 4) Development of New Products • 5) Decrease in Pounds of Pesticide Use • 6) Decrease Numbers of Pesticide Apps • 7) Lower Environ. Impacts of Pesticide Use • 8) 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 Funding 11) Reduced no. of pesticide treated acres 12) Shift in reliance to less-toxic pesticides 13) Creation of more IPM Options 14) Biocontrol projects funded then and now 15) Changes in Producer IPM Knowledge, Opinions, Skills, and Aspirations
US General Accounting Office - 2001 Management Improvements Needed to Further Promote IPM 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."

A Method to Measure theEnvironmental Impact of Pesticides (EIQ)1992J. Kovach, C. Petzoldt and J. TetteIPM ProgramCornell UniversityNYS Ag. Exp. Sta.Geneva, NY http://www.nysipm.cornell.edu/publications/EIQ.html
Over 200 pesticides evaluated (insecticides, fungicides, herbicide) 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 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 Farmworker Consumer Ecological http://www.nysipm.cornell.edu/publications/EIQ.html

Methods of Measuring IPM Adoption 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
Pesticide Price Model Goal: To develop a “common currency” to assess the environmental and economic impact of IPM programs that can be easily communicated.
Price = Raw materials • + Capital • + Production • + Transportation • + Profit • (+ Environmental Cost)
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 aleacherit 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

Behavior Changes & IPM Implementation • • Negative Incentives • Pesticide taxes • •Positive Incentives • IPM Marketing • Trading 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
