What is considered the most important maintenance practice for pesticide equipment?

• A. Thorough and consistent cleaning
• B. Regular calibration
• C. Lubricating moving parts
• D. Replacing hoses annually

Answer: (A)

Thorough and consistent cleaning is the most important maintenance practice because residues from pesticides, dirt, and debris left in the system can cause nozzle clogging, inaccurate flow, cross-contamination between applications, and corrosion. Cleaning lays the foundation for everything else: it preserves spray quality, protects worker safety, and extends the life of pumps, seals, and nozzles. If cleaning is neglected, even well-calibrated equipment can misread flow rates or spray patterns, lubricating moving parts or replacing hoses won’t fix contamination, and worn components may fail prematurely. Keeping equipment clean ensures that calibration, lubrication, and component replacements work as intended and that applications stay accurate and safe. After each use, flush lines, clean nozzles, screens, and filters, inspect for wear, and store the equipment per manufacturer instructions.
