Read the label of each pesticide for any special considerations.

Definitions:

Pesticide - Pesticides are a group of products that includes insecticides, herbicides, algicides, miticides and several other products specific to a particular target. Insecticides are used to control insects. Herbicides are designed to control plant growth.

Environment - The environment is everything around us. The environment includes not only the natural elements, such as trees, shrubs and water but, also includes people and manmade components (buildings, swing sets, etc.).

When: Contamination can occur when a pesticide moves from the target site into an area that is not intended to be sprayed

Example: a herbicide goes off the intended target site and moves into the storm sewer or drifts off of the right of way

Example: herbicide carried home on contaminated clothing

Special Recommendations:

Sensitive areas. When applying any herbicides, be aware of sensitive sites around the area

A. Outdoor sensitive areas include:

1. Ground water that is near the surface or that is easily accessed. Examples: wells, sinkholes, porous soil.

2. In or around surface water

3. Near or around endangered species habitats

4. Near honeybee sites, wildlife refuges or parks

5. Near gardens, food, or feed crops

B. Indoor sensitive areas include:

1. Where people live, work, or are cared for

2. Where food or feed is processed, prepared, or served

3. Where domestic or confined animals live, eat, or cared for

4. Where other ornamental plantings are grown or maintained

Pesticide movement:

A. The movement or spreading of a pesticide from target area to non-target area. Pesticides can move or spread in different ways:

1. Drift: the movement of pesticides by wind or air currents

2. Leaching and run off: the movement of pesticide by water

3. Through plants, clothing, boots and animals

B. Effects on non-target plants and animals:

1. Drift from the target site may injure pets, people, sensitive plants, wildlife and livestock

Read the Label of each Pesticide for any Special Consideration

Refer to Crop Data Management System's website for label information.

2. Poorly timed applications can kill insects and plant pollinators

3. Pesticide run-off may harm fish of other aquatic life

C. We must remember that the environment is everything around us

D. We should take precautions to protect our environment when applying pesticides
