This two-year project was conducted on an organic polyculture farm in southern Québec (Ferme des Quatre-Temps).
The first stage of the project focused on describing the polyculture system and how the hedges are planted and maintained. Interactions between the polyculture and the hedges were studied, based on the insects associated with crops in the cabbage family. Insects were sampled on plots to check for parasitism of immature pest stages (caterpillers and pupa) on the crops and in adjacent hedges to determine what natural enemies and pollinators use them as a refuge. This data was used to identify the plant species most used by natural enemies and pollinators. The project also looked at the economic aspects of planting recommended species and the economic benefits of various control strategies for Lepidopteran pests of the cabbage family.
From 2017 to 2018

Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
