Academic Standards for Academic Standards for Environment & EcologyEnvironment & 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.

Learning ObjectivesLearning 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.

Benefits of IPM Drawbacks of IPM

Benefits of IPMBenefits 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.

Benefits of IPMBenefits 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.

Benefits of IPMBenefits of IPM

Less Damage to Non-target Organisms. Some beneficial organisms are mistakenly effected

or killed by pesticides meant to target other organisms.

Benefits of IPMBenefits of IPM

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

Benefits of IPMBenefits of IPM

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

soil of vital nutrients.

Drawbacks of IPMDrawbacks of IPM

May alter local ecosystems. Introducing predators, parasitoids, and pathogens

changes the balance in an ecosystem.

Drawbacks of IPMDrawbacks of IPM

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

eliminate them.

Drawbacks of IPMDrawbacks 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.

Drawbacks of IPMDrawbacks of IPM

May lose more crops. Results occur more slowly initially.

Drawbacks of IPMDrawbacks 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
