Some pesticides used near water may contaminate the water supply. Continuous use of certain pesticides may induce resistance in the pests they are designed to control, thus requiring the gardener to switch to more toxic substances. Some pesticides do not break down easily and can remain in the environment for years. Read the label when you purchase a pesticide, and again before mixing or applying it. If you are confused about any part of the label, consult your Extension agent or a representative of the product manufacturer.
Many pesticides now list a toll-free number for consumers.
The label includes specific information that you should be aware of and learn to understand. The registration and use of pesticides are regulated by the United States Environmental Protection Agency and the Virginia Department of Agriculture and Consumer Services. It is also illegal to exceed the given rate of application on the label. For more information on selection, planting, cultural practices, and environmental quality, contact your local Virginia Cooperative Extension office , or view a list of other on-line publications in this series. If you want to learn more about horticulture through training and volunteer work, ask your Extension agent about becoming an Extension Master Gardener.
