The release of trichogramma wasps using tricho cards has been successfully employed in Québec to control the European corn borer in fresh sweet corn. Farmers growing sweet corn for processing also want to use trichogramma to control the insect, provided the release method is consistent with the technical and economic realities they face. In 2019 and 2020, four sites in the Montérégie region will be targeted for the experimental release of trichogramma by aerial spraying. A plane will be used to release a spray containing host eggs parasitized by trichogramma pupae over the test plots. In order to assess the presence of the European corn borer, a control plot (no trichogramma release) will be designated at each site as well. The research will involve monitoring the European corn borer population, as well as assessing the quality of trichogramma released and the crop damage. Lastly, an economic analysis of different European corn borer control strategies (aerial spraying of pesticides versus the use of trichocards) will be conducted.
From 2019 to 2021
Pest, weed, and disease control
Crop dusting to control insect pests will one day soon be replaced by the release of tiny insect pest enemies.

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.
This project will provide a better understanding of interactions between a vegetable polyculture system and hedges composed of shrubs and perennials in order to enhance the impact of beneficial insects on vegetable crops.
This project aims to develop a GHD-based fertilizer management system using split band applications for high-N-demand crops grown in rows, e.g., summer cabbage.
