If you suspect mislabeling or misapplication of a pesticide, which steps should you take?

• A. Switch to different product without documentation
• B. Ignore and continue
• C. Stop using product; document; notify supervisor or MDA; preserve label and samples; do not apply again until clarified
• D. Keep applying until problem resolved

Answer: (C)

When you suspect mislabeling or misapplication, you should stop using the product immediately and take careful, documented steps. Halt application, document what happened (product name and batch if available, location, date/time, rate and method, crops or targets affected, symptoms seen), notify the supervisor or the Minnesota Department of Agriculture, preserve the label and any product samples or affected materials, and wait for clarification before applying again. This approach protects people, crops, and the environment and ensures an official review can determine what happened and what corrective actions are needed. Posing no action or continuing to spray without documentation can lead to further harm and legal issues, while quickly escalating the issue with proper records and oversight helps prevent additional problems.
