Product description


Tricho-Pepper® cards offer an effective solution to protect hop and pepper crops against European corn borer . Inside each card are parasitic wasps, Trichogramma ostriniae. Once emerged, the females, measuring only 1mm, lay their eggs inside butterfly eggs. Trichogramme larvae develop by feeding on the embryos. The eggs hatch in about two weeks to create a new generation of these beneficial insects, reducing crop damage. Used in Canada and the United States with proven effectiveness, this biological approach is essential to maintaining healthy farms without the use of insecticides.

Targeted crops

  • Hop
  • Piment


Targeted pests

  • European corn borer (Ostrinia nubilalis)

Application Instructions

To achieve optimal results, start introducing the trichogrammes as soon as the pest is detected or at the fruiting stage. If the trichogrammes are not introduced before the eggs are laid, they will not be able to prevent the caterpillar’s development.

The number of cards to be introduced depends on the area to be treated. The trichogrammes should be distributed evenly both lengthwise and widthwise. Poor distribution could lead to unprotected areas. The first card should be placed 3 meters from the edge of the field, and subsequent cards should be placed 14 meters (width) and 7 meters (length) apart.

New cards should be introduced every week. On average, 5 releases per season are required to achieve good control against the pest.

Storage Instructions

To get the most out of this product, handle it with care using the provided hook or its edges. Change the card every week and keep the other cards in the refrigerator for up to four weeks to keep them performing well. Avoid freezing.
