Which statement about pesticide equipment cleanup is false?

The statement regarding leaving pesticide residues in the spray tank when changing products is false because it goes against best practices for pesticide equipment cleanup. Proper equipment cleanup is essential for several reasons, including preventing chemical contamination, protecting the environment, and ensuring safety when switching between different pesticide products. Residues from one pesticide can react with another, leading to unintended chemical interactions that could pose risks to both human health and the environment.

Thoroughly rinsing the equipment and removing all residues ensures that the next product used can work as intended without interference from leftover chemicals. Therefore, it is crucial to always rinse the spray equipment and avoid leaving any residues in the tank before switching products.

The other statements reflect proper cleaning procedures: adding lightweight oil helps maintain the tank, rinsing with a water-detergent solution ensures thorough cleanliness, and using commercially available cleaning compounds can assist in effectively removing residues.
