Recommendations on Resistance Management for Dicarboxamides


General Use Recommendations

  • Minimise the selection pressure by minimising the number of applications. As a guide, do not apply more than two to three per crop per season.
  • Restrict applications to those times when Botrytis infection pressure is high.
  • Maintain regular prolonged times without exposure to dicarboximides.
  • Where resistance is well established, use combinations to stabilise Botrytis control, but their application must follow the same rules as for dicarboximides alone.

Note that individual countries will now have their own, more detailed, use guidelines for specific crops.
