The use of the most commonly used weed-killer in the world, glyphosate, which is found in the product Roundup, is likely to soon be banned in your community and in your park system. Although EPA declared the pesticide safe in 2019, the controversy over the safety of glyphosate rages, fueled by a growing body of evidence regarding the negative effects on human health and the environment. Cities and counties are already taking action to ban the use of glyphosate in public places, leaving park and rec agencies few alternatives to halt the spread of invasive species and control aggressive weeds in park landscapes. What will your agency do to control weeds in your parks when this herbicide is banned?  Learn about possible alternatives that are safer and less toxic and which the public will support even if your park landscape areas have a lot more weeds than you ever thought they would have before.
