If improperly used, these chemicals also can injure or kill plants or animals that were not intended to be controlled. Certain pesticides that don't readily break down can accumulate in the food chain. Unless otherwise directed, don't water an area immediately after applying these chemicals to it. This might cause them to run off with the extra water into a storm sewer or stream. Don't throw pesticides or herbicides in the trash, or pour them on the ground or down a drain.
