Which practice helps minimize cross-contamination between products when filling spray tanks?

• A. To ensure the sprayer looks uniform.
• B. To prevent cross-contamination between products.
• C. To reduce required PPE.
• D. To shorten cleaning time.

Answer: (B)

Minimizing cross-contamination between products relies on preventing any residue from one product from carrying into the next fill. When you fill a spray tank, residues can cling to hoses, valves, and the tank itself. If those residues mix with a new product, you can get crop injury, changed product performance, or label violations. The best practice is to actively stop residue transfer by cleaning and flushing the system thoroughly between products, using dedicated tanks or separate fill lines when practical, and following the label’s instructions for washout and mixing order. By ensuring the system is free of previous product residues before the next fill, you protect crops, maintain efficacy, and stay compliant. Practices that just focus on appearance, reducing PPE, or shortening cleaning time don’t address the core issue and can increase the risk of cross-contamination.
