Applicators and the public share concerns about how pesticides may harm the environment. Initially, hazards to humans were the primary reason the U.S. Environmental Protection Agency (EPA) decided to classify a pesticide as a restricted-use product. Now, more and more pesticide labels list environmental effects (such as contamination of groundwater or toxicity to birds or aquatic organisms) as reasons for restriction. Anyone who uses a pesticide—indoors or outdoors, in a city or on a farm—must consider how that pesticide affects the environment.
After completing this course, participants will be able to:
• Describe how pesticide applications can affect the environment.
• Explain how to prevent pesticide drift, runoff, and movement to nontarget areas.
• Discuss how to prevent pesticide residue accumulation associated with mixing, loading, and
