Pesticides in the Environment
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.
Civilization has been combating insects and other pests throughout history. A pest is an undesirable organism that injures
humans, desirable plants and animals, manufactured products, or natural substances. Many insects, pathogens (disease-causing organisms, such as viruses, bacteria, or fungi), plants (known as weeds), mollusks (slugs and snails), fish, birds, and a variety of mammals (from mice to deer) compete for our crops and livestock. As the battle between humans
and pests continues over time, so will innovative methods of control.
How Fungicides Work
This course provides the learner with the basics of fungicides and how they work. The process of how fungal spores germinate and penetrate the leaf structure are explained with easy to follow diagrams and instruction. Plant appearance, the status of fungal infections, and fungicide mechanism of action are discussed to provide a framework from which to formulate treatment strategies.
After completing this course participants will be able to:
- Describe how pesticide applications can affect the environment.
- Discuss how to prevent pesticide residue accumulation associated with mixing, loading, and equipment washing.
- Discuss the importance of pest identification in pest control.
- Describe how pest population levels trigger control procedures.
- Give several reasons why pesticide applications may fail.
- Gain an understanding of how fungicides penetrate the structures of a targeted plant.
- Tailor a management strategy that addresses the prevention, identification, and treatment of fungal infections in plants.
