Which statement about pesticide equipment cleanup is false?

The statement that leftover pesticide residue in the spray tank is permitted when changing products is false because effective pesticide application requires that all residues be removed from the equipment to prevent cross-contamination and chemical reactions. Different pesticides have unique chemical compositions and properties; therefore, even small amounts of leftover pesticide can compromise the effectiveness of the new product or lead to unintended reactions that may harm the environment or the applicator's health.

Thorough equipment cleaning ensures not only the safe application of pesticides but also compliance with regulations and best practices, which emphasize the importance of using equipment that is free from residues of previous chemicals. This is particularly essential in maintaining accurate dosages and ensuring that each application functions as intended without interference from prior products. Other statements focus on proper cleaning and disposal practices, reinforcing the necessity of rigorous cleaning protocols in pest control.
