What is D-Act® Spray System Cleaner?

  • D-Act® Spray System Cleaner uses the Fenton reaction to deactivate dicamba during the cleaning process.
    • The Fenton reaction is an oxidation process by which organic compounds are degraded.
  • D-Act Spray System Cleaner has been tested for several years by Monsanto/Bayer and university researchers. Mississippi State University research has shown that the Fenton reaction coupled with a dilution process of the triple rinse reduces the occurrence of spray system contamination.
  • D-Act Spray System Cleaner contains 2 gallons of ferrous sulfate (green) and 2 gallons of 27% hydrogen peroxide (clear).

Why is D-Act Spray System Cleaner Important?

  • The D-Act Spray System Cleaner has been proven to be applicable to a wide range of lean aqueous waste streams. We have found that utilizing the Fenton reaction in spray systems can improve the cleanout of dicamba.
  • A two-part D-Act Spray System Cleaner has been specially formulated to work in conjunction with Roundup Ready® Xtend Technology.
