If you have experienced a suspected dicamba incident contact the Iowa Department of Agriculture and Land Stewardship (IDALS) at 515-281-8591 to file a report. You may file an “Incident Report” or a “Documentary Report” with the IDALS Pesticide Bureau. 

Reporting dicamba incidents helps evaluate the impact of dicamba use in Iowa and provides valuable information.

Incident Reports

If you choose to file an Incident Report, IDALS will collect information about the incident and will visit the site and do pesticide applicator follow-up. Additionally, the report needs to contain:

  1. The name of the person allegedly responsible for the application of said pesticide;
  2. The name of the owner or lessee of the land on which the crop is grown and for which damage is alleged to have occurred;
  3. The date on which the alleged damage occurred; and a
  4. Brief description of the incident.

This report must be filed within 40 days after the alleged date that damages occurred. If a growing crop is alleged to have been damaged, the report must be filed before 25% of the crop is harvested. Additional information on filing an Incident Report can be found at

Documentary Reports

If you request to file a “Documentary Report,” IDALS will collect information about the incident but will not visit the site or do any applicator follow-up. Documentary reports are included in IDALS’ total number of pesticide complaints.
