What should you do if you realize you applied the wrong product or wrong rate?

• A. Stop applying, do not reapply, notify your supervisor, and follow the label’s or regulatory authority’s emergency procedures.
• B. Continue applying until the label says stop.
• C. Switch to a different product immediately.
• D. Discontinue field operation and document for later.

Answer: (A)

When you realize you’ve applied the wrong product or the wrong rate, the top priority is to stop applying and prevent any further exposure or harm. Do not reapply, because continuing the misapplication could worsen crop injury, increase drift or environmental impact, and raise safety risks for workers.

Next, tell your supervisor right away so someone with authority can coordinate the next steps and ensure proper follow-up. Then act on the label’s emergency procedures or the regulatory authority’s instructions. Those steps are there to contain the situation, protect people and the environment, and ensure the incident is reported and handled correctly.

Documentation is important, but it comes after you’ve stopped the application and started the emergency response. The other options would allow the misapplication to continue, introduce new risks by switching products without guidance, or delay action and reporting.
