An innovative biological fungicide with three modes of action that forms a shield of protection on plants’ surfaces to protect against disease.

  • Targets botrytis and powdery mildew in grapes
  • Complements chemistry-based programs and helps manage the potential for resistance
  • Sets the quality standard for purity, performance and reliability
  • With no recordable residues, Serifel™ fungicide provides greater flexibility by extending the window of application, especially near harvest
  • Can be used for organic production

  • Ensure the spray tank is clean before use.
  • Fill the spray tank 3/4 full of water and start agitation.
  • The pH of the spray solution should be between 4 and 9.
  • Before adding Serifel to the spray tank, create a pre-slurry by mixing the required amount of Serifel with water in a bucket.
  • With the spray tank agitation system running, add the Serifel pre-slurry to spray tank.
  • Add the required amount of tank-mix partner, if applicable.
  • Add the recommended amount of adjuvant, if applicable.
  • Continue agitation while filling the remainder of the spray tank, throughout mixing and application.
  • The spray mixture should be applied shortly after mixing; do not allow the spray mixture to sit overnight.
  • After use, clean the spray tank according to label precautions.
  • The product mixture should be applied shortly after mixing. DO NOT store mixed suspensions of Serifel overnight.

Application tips

Rainfastness – 3 hours
Restricted entry interval – 4 hours or until sprays have dried.
Resistance management – Serifel is an excellent resistance management tool to include in an IPM program. It can be used in combination or rotation with other chemistries to prevent the development of resistant strains.

Pre-harvest interval

0 days for all labeled crops.
