  3. Sources of Contamination of Spray Equipment: • Improper or inadequate cleanout • Redissolved residues • Contamination from using remix water • Poly fiber tanks, old hoses • Low-rate actives with highly active molecules • Presence of tank mix partners • Mini-bulk contamination - repackaging

  4. Ways to reduce or avoid contamination: • Use pesticide resistant materials • stainless steel tanks • Removing enough liquid during the cleanout process • ‘Follow’ proper cleanout procedures • label information if provided • Extension publications • Adopting engineering controls • tank rinsing nozzles • Use special cleaners • Use a dedicated sprayer

  5. Steps for cleanout: • Work in a safe area (environment and people). • Hose down inside of tank • Fill tank have full and flush out through the nozzles. • Repeat and include a proper cleaning agent. • Flush final time with clean water.
