Which statement about pesticide equipment cleanup is false?

• A. Leave pesticide residues in the spray tank when changing products
• B. Rinse the tank between products
• C. Empty and properly dispose of containers according to label
• D. Clean nozzles and hoses after use

Answer: (A)

The important principle here is preventing cross-contamination and staying compliant with label directions during cleanup. You should rinse the spray tank between products to remove any remaining residues, because even small amounts can mix with the next product and change its rate, accuracy, or safety. Proper cleanup also means emptying and disposing of containers according to the label to prevent environmental contamination and ensure safety, and thoroughly cleaning nozzles and hoses after use to avoid residue buildup and clogs. Leaving pesticide residues in the tank when switching products contradicts these practices and can lead to unsafe applications, crop damage, and regulatory violations.
