Description

An initial laboratory phase was aimed at comparing the efficacy of two parasites T. brassicae and T. ostriniae on leek moth. The purpose of a second, two-year phase, conducted at the Organic Agriculture Innovation Platform in Saint-Bruno-de-Montarville, is to test the ability of both parasites to reduce leek moth damage in the field compared to a control. A technical and economic analysis will look at the costs and benefits of trichogramma releases.

Objective(s)

  • Determine in the lab and the field the capacity of two species of trichogramma wasps raised commercially in Québec (T. brassicae and T. ostriniae) to parasitize leek moth eggs and reduce larval populations and the damage they cause on organic leeks
  • Develop a cost-effective, ecofriendly control strategy that protects natural enemies

From 2015 to 2019

Developing a web app to facilitate the viewing and interpretation of potato soil health analyses

This project aims to develop an accessible and user-friendly web application that will let stakeholders search the IRDA potato soil database, one of the largest in Canada, to visualize the impact of growing practices and protocols on the biological, physicochemical, and agronomic characteristics of soils cultivated with different cropping systems.

Developing fertilization strategies for organic garlic farming that combine green and farmyard manure, while taking their N and P supply dynamics and soil quality impacts into account

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.
