What should you do if a pesticide label contains a critical error?

• A. Use the product but reduce the rate and recheck the label.
• B. Substitute with a different product without verifying.
• C. Do not use the product; contact the manufacturer or regulatory agency to verify correct usage or obtain an updated label.
• D. Modify the label in the field to correct the error.

Answer: (C)

Pesticide labels are the legally binding instructions for safe and effective use. If you find a critical error on a label, you should not use the product. Instead, stop applying it and contact the manufacturer or the appropriate regulatory agency to verify the correct usage or obtain an updated label. This ensures you’re following authoritative guidance and protecting yourself, workers, crops, water, and the environment from potential harm. Trying to adjust the rate, timing, or site, or substituting with another product without verified guidance, can lead to crop injury, ineffective pest control, or legal penalties. Never modify a label in the field. Obtain the corrected label or official guidance before proceeding.
