Theme Outline

• Lesson 5.3
• Effects of IPM on the Environment and Society
• Benefits of IPM
• Drawbacks of IPM

3
Academic Standards for Environment Ecology

• Standard 4.5.10.C
• Determine the effects of integrated pest
  management practices on society over time.
• Analyze the risks to the environment and society
  associated with alternative practices used in
  integrated pest management.
• Analyze the benefits to the environment and
  society associated with alternative practices
  used in integrated pest management.

4
Learning Objectives

• Students will assess various levels of control
  within different integrated pest management
  practices, including increased immunity to
  pesticides, food safety, sterilization, nutrient
  management, and weed control.
• Students will analyze the risks to the
  environment and society associated with
  alternative practices used in integrated pest
  management.
• Students will analyze the benefits to the
  environment and society associated with
  alternative practices used in integrated pest
  management.

5
Effects of IPM on the Environment and Society

• Benefits of IPM
• Drawbacks of IPM

6
Benefits of IPM

• Less pesticide residue on food.
• The EPA considers pesticide residue on food one
  of the most serious environmental health concerns
  in terms of the risk of cancer.

7
Benefits of IPM

• Less chance of pesticide resistance.
• When pesticides are used over a long period of
  time, pests can develop a resistance (or
  immunity) making pesticides less ineffective.

8
Benefits of IPM

• Less Damage to Non-target Organisms.
• Some beneficial organisms are mistakenly effected
  or killed by pesticides meant to target other
  organisms.

9
Benefits of IPM

• Lower costs to farmers.
• Few pesticides used, fewer pesticides to buy.

10
Benefits of IPM

• Preserves nutrients in the soil.
• Planting one single crop year after year depletes
  the soil of vital nutrients.

11
Drawbacks of IPM

• May alter local ecosystems.
• Introducing predators, parasitoids, and pathogens
  changes the balance in an ecosystem.

12
Drawbacks of IPM

• Can contaminate the environment.
• IPM lessens the use of pesticides but does not
  eliminate them.

13
Drawbacks of IPM

• Does not eliminate all pests.
• What is the goal of IPM again?
• Not eliminate but use forecasting and weather
  data to devise a plan to bring pest populations
  down to acceptable levels.

14
Drawbacks of IPM

• May lose more crops.
• Results occur more slowly initially.

15
Drawbacks of IPM

• Can require intensive planning.
• Considerations such as
• Knowledge of pests biology, their lifecycle, and
  natural enemies
• Knowledge of how IPM can be used to control pest
  populations
