Which statement about pesticide equipment cleanup is false?

The statement regarding leftover pesticide residue in the spray tank being acceptable when changing products is false because it is essential to ensure that there is no cross-contamination between different pesticides. Even small residues from one product can react with another or reduce the effectiveness of the new pesticide being applied. This can lead to ineffective pest control and potentially harmful effects on the environment.

In pest control practices, rigorous cleaning of all equipment, including spray tanks, is crucial to maintain the integrity of the applications and to protect non-target organisms. Hoses must be thoroughly rinsed to remove any pesticide remnants that could contaminate future applications. Following label instructions is a best practice as it ensures compliance with safety standards and legal regulations, promoting both effectiveness and safety in pesticide application.
