The European corn borer Ostrinia nubilalis is the main pest of fresh and processing sweet corn in Québec. For the past 20 years, producers have used biological control to protect their sweet corn against the borer. According to a well-defined protocol (number of wasps per hectare, number and location of releases), cards carrying trichogramma eggs are installed on the corn plants during the pest’s egg laying period. The goal of this project is to boost to 200 the number of fresh and processing sweet corn producers in Québec using trichogramma to control European corn borer. Wider adoption of this biocontrol method in Québec will limit pesticide sprays against the European corn borer and thus help protect the environment and human health and reduce the associated risks.
From 2017 to 2019
Pest, weed, and disease control
This technology transfer project will lead to a significant reduction in the number of insecticide spray applications needed to control the corn borer across Québec.

By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.

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.
