Directions for use

Directions for use


  • Shake bottle or container well before use
  • Fill the tank with half of the required amount of water
  • Add the required amount of Nopath
  • Stir well
  • Add the remaining amount of water while maintaining agitation
  • Spray or drench immediately after preparation


Nopath can be applied via drench or drip at the base of the plant around the roots or sprayed on the plant canopy. Do not apply Nopath with fogging or low volume mist devices

Application via drip irrigation:

  • Make sure Nopath does not remain in the irrigation system during the night but ends up in the substrate instead
  • Use disinfectants regularly to keep the irrigation system clean, but do not use Nopath at the same time as the disinfectant.

Application via spraying:

  • Spray as a full canopy spray using standard spraying equipment with high pressure. Use a fine nozzle of less than 300 microns for best plant coverage
  • The pH of the solution should be between 5 and 7
  • Rinse spray equipment thoroughly after use to avoid clogging


  • The dosage of Nopath depends on the crop and disease situation and should always be adjusted to the particular conditions
  • Apply 0.1-0.5 litre/100 litre water
  • Always check the product label for more information
  • Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation


Start application when diseases start to appear.

  • Do not apply if rain is expected within 4 hours after application


  • Nopath is compatible with foliar fertilizers except those containing calcium. Find out which products are compatible or contact your local representative for advice
