Which statement about pesticide equipment cleanup is false?

• A. Leave pesticide residues in the spray tank when changing products
• B. Sprayers should be thoroughly rinsed with a water detergent solution for several minutes
• C. Rinse the system with plain water after use
• D. When getting ready to store your sprayer, add some lightweight oil to the tank before the final flushing

Answer: (A)

Removing pesticide residues completely is essential to prevent cross-contamination, protect crops, and stay compliant with labels and safety rules. The practice of leaving residues in the spray tank contradicts these goals, so it isn’t correct. Thorough cleanup starts with rinsing the sprayer using a water-detergent solution for several minutes to dissolve and lift remaining product. After that, you rinse with plain water to wash away the detergent and any lingering residues. When getting ready to store, adding a small amount of lightweight oil to the tank can help coat internal surfaces and protect components during storage, and then you perform the final flushing to remove residues and oil before putting the sprayer away.
