Tricho-Gard

Trichogramma small wasps to control leek moth

Description


Tricho-Gard® is a biological alternative to protect garden crops and gardens against butterflies and moth pests. Inside the card, there are trichogramma pupae in host eggs, a small moth egg parasite wasp of the species Trichogramma brassicae.

The adults Trichogramma wasps are tiny, measuring less than 1 mm. After mating, females actively seek lepidopteran eggs such as Leek moth (Acrolepiopsis assectella), Cabbage moth (Plutella xylostella), Cabbage looper (Trichoplusia ni) and Cabbage white (Artogeia rapae). She lays her eggs inside these. The wasp larvae develop and feed on the pest embryo. A new generation of trichogramma will emerge 2 weeks later.

Trichogramma brassicae has been selected specifically for field of Alliacea and Brassicaceae (cruciferous) family crops. For several years, its use has been an alternative to conventional insecticides and bio-insecticides like Bacillus thuringiensis (Bt) to garlic, leek and cruciferous growers.The card can also be used in combination with Bt products to enhance the protection of some more sensitive area.

The Use of Tricho-Gard® can be applied without pesticide equipment, at all hours of the day and in different environmental conditions (rain, wind, soggy soil, etc.).
