Instructions for use

  • Apply at 0.5-20 parasites per m² depending on whitefly occurrence and intensity
  • Use at low doses to prevent whitefly establishment
  • Use a selective insecticide to clean up existing populations

 

Blister:

  • Remove the sheet of blister packs from the envelope and separate along the perforations
  • Open the flap at the back of the blister
  • Hang on the plant in the shade, out of direct sunlight.

Bottle:


  • Open the bottle in the glasshouse in the early morning or evening when light
    conditions are low
  • Do not release in bright sunlight
  • Sprinkle the product directly onto the leaves in areas where whitefly occurs
  • Spread evenly in the crop
  • Use as many release points as possible
  • Keep bran carrier out of reach of rodents and excessive humidity


Important information:

  • Eretmocerus populations are 50% female and 50% male, unlike Encarsia where males occur only rarely
  • If there is a risk of virus transmission to plants from invading Bemisia adults, it may be preferable to use an insecticide and follow up later with Eretmocerus releases
  • Where only Trialeurodes is present, consider using Encarsia rather than Eretmocerus
