It has been estimated that an average acre of a well maintained urban lawn receives an annual input of five to seven pounds of pesticides. If you determine a pesticide is necessary, REMEMBER:
Don't buy more than you need
Only apply what is necessary
Do not apply in the rain (unless specified)
Never apply on bare ground or near wells, ponds, streams, etc.
Never dump excess pesticides on the ground or into the storm sewer
Consider sharing leftovers (in their original containers) with neighbors
When a container is empty, rinse three times (each time pouring into a sink)
Use a Clean Sweep Program to dispose of pesticides and containers properly
Here are some simple steps you can take to help keep our water clean. A few simple changes can make a big difference!
Maintain a healthy lawn by mowing frequently
Practice hand-weeding with sharp blades set at 2 ½ to 3 inches
Evaluate if a pesticide is necessary
Use mulches to reduce weeds
Spot treat weed and insect areas
Learn to live with a few weeds!
