  • Utilize newest ‘R’-rated hybrids, a product of extensive disease breeding
  • Scout fields, properly identify and monitor infection
  • Where possible, extend canola rotations to a minimum of once every three years to reduce inoculum and canola volunteers
  • Manage susceptible weeds and volunteer canola to reduce inoculum sources
  • Use a registered fungicide at the proper timing
  • Utilize Vercoras® seed treatment to protect cotyledons through the critical infection period and reduce the potential for stem infection
