Directions for use

Directions for use


  • Hang sachets in sheltered locations in the crop, not exposed to direct sunlight
  • Sachets already have an exit hole
  • Hold sachets by the cardboard strip at the top, to avoid damaging the predatory mites


The dosage of Swirski-Mite LD depends on climate, crop and pest density and should always be adjusted to the particular situation. Start introduction preventively or as soon as the first pest mites are detected in the crop. Use at least 4,000 sachets per ha and hang them evenly spaced in the crop. Release should be repeated after 5-6 weeks if the pest is not controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
