OISC Clean Sweep Pesticide Disposal Program is a great opportunity to legally dispose of unwanted pesticide products at little or no cost. 

The 2022 Clean Sweep Pesticide Disposal Program sponsored by the Office of the Indiana State Chemist (OISC) offers statewide pesticide collection sites in Wabash, Bartholomew, Daviess, Randolph, Porter 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 others 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).  

Visit the Office of the Indiana State Chemist (OISC) website to download the participant form at or contact Nathan Davis at 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 5, 2022.  Then bring your labeled, leak free and safe to transport containers to the collection site. DO NOT mix materials. In case of an emergency, you should bring with you a list of products you are carrying and a contact phone number. 

The drop off time is 9 a.m. to 3 p.m. on August 25, 2022 at the Hendricks County Fairgrounds in Danville, IN.

Questions can be emailed to Nathan Davis.
