Sound Off: What kind of herbicides and chemicals does the city use in the parks and other areas? And why do they use them?
Megan Gilliland, the city’s communications manager, provided this answer: City staff uses pesticides as a tool to control unwanted and noxious weeds such as poison ivy and other plant pests such as bagworms in selected areas. A map of green parks and other limited-spray areas is available at lprd.org. The department created an Integrated Pest Management Policy including an accepted pesticide materials list several years ago. All chemicals used are Category Level 3 or 4. When spray applications are occurring, the department posts signs in advance of spraying and leaves the signs up for 24 hours after completion. The parks department also uses alternative methods of weed control including sheet and wood chip mulching and mowing grass high to help control weeds and reduce use of pesticides.
