Proper Sprayer Cleanout Prevents Contamination

Follow label guidelines for sprayer cleanout after any herbicide application.

Proper sprayer cleanout is key to avoiding damage to non-target crops. After applying DuPont™ FeXapan™ herbicide Plus VaporGrip® Technology, triple-rinse sprayers and all sprayer components that come in contact with the spray solution, including tanks, pumps, hoses, connectors, screens, nozzle bodies and nozzles.

Prior to applying an approved dicamba for a labeled use:

  • You must ensure that the entire spray system used to apply this product is clean before using this product (other dicamba products)
  • Failure to properly clean the entire spray system can result in inadvertent contamination of the spray system
  • Small quantities of dicamba may cause injury to non-dicamba tolerant soybeans or cotton and other susceptible crops
