OISC Clean Sweep Pesticide Disposal Program is a great opportunity to legally dispose of unwanted pesticide products at little or no cost. The 2025 Clean Sweep Pesticide Disposal Program sponsored by the Office of the Indiana State Chemist (OISC) offers statewide pesticide collection sites in LaPorte, Vigo, Decatur, Clark, Whitley, and Hendricks counties in August. This is a great way for farmers, public and private schools, ag dealers, nurseries, golf courses, cities, towns, municipalities, county units of government and any others receiving this notice to dispose of suspended, canceled, banned, unusable, opened, unopened or just unwanted pesticides (weed killers, insecticides, rodenticides, fungicides, miticides, etc.) for free (up to 250 pounds per participant), Pesticides Only. Visit the Office of the Indiana State Chemist (OISC) website to download the participant form at oisc.purdue.edu or contact Mitch Trimble at cleansweep@groups.purdue.edu or 765-494-7142 to have a participant form emailed. Those wanting to participate are required to complete and submit the participant form by mail, e-mail, or fax by August 8, 2025. Then bring your labeled, leak free and safe to transport containers to the collection site. DO NOT mix materials. Questions can be directed to Mitch Trimble at cleansweep@groups.purdue.edu or call (765) 494-7142.
