Tricho-Corn

Trichogramma wasps card hang on a corn plant to control European corn borer





Description


trichogrammes Tricho-Corn® is a natural product used to control the European corn borer (Ostrinia nubilalis) in outside commercial production of Sweet corn, Cannabis and Hemp. Inside each Tricho-Corn card, there are 8000 Trichogramma pupae of Trichogramma ostriniae. This species has been selected for maximum results in suppressing European corn borer eggs.

Trichogramma are tiny wasps (1 mm) that parasitize moth eggs. In agriculture, they are used to control more than 200 moth and butterfly pest species.

Trichogramma ostriniae pupae are glued to cards and introduced in field. Once set up, adult trichogramma will emerge after 2 to 7 days, depending on environmental conditions. Upon emergence, the female Trichogramma wasps will actively search for moth eggs on the surface of the leaves. Once detected, she lays her eggs inside them. The Trichogramma larvae will grow inside the moth eggs and feed on the future corn borer larvae in formation. This will cancel the future generation of corn borer.

Application


Trichogramma

Release should start as soon as soon as moths are first detected (pheromone lure traps) or in mid-june (for the Univoltine generation). If Trichogramma wasps are not released before laying period, they can not prevent the development or larvae (= damage).

The introduction depends of the crop area. Trichogramma wasps must be uniformly distributed (by length and width). A bad distribution would cause unprotected areas.

The first card is placed 7 meters from the edge of the ?eld and the next one every 7 meters. For example, for a plot of 100 meters by 100 meters:

100 m wide/ 14 m = 7 introduction rows*

100 m long/ 14 m = 7 cards per introduction row*

*Round to the nearest unit.

Put new cards avery week from the moth emergence until the end of his cycle. In general, 5 weeks are sufficient. To prevent removal of trichogramma not emerged, keep the card in field for minimum of 3 consecutive weeks.
