Research Projects

This project will draw recommendations to reduce fugitive emissions through technical means or agricultural practices.

The goal of this project was to measure the impact of irrigation management on nitrogen uptake and available soil nitrogen on several cultivars under commercial production conditions.

IRDA drew up a list of insects and mites in Québec known to be or likely to become resistant to pesticides.

The aim of this project is to evaluate this aspect of potato production economics to assist producers and their advisors.

The aim of this project was to identify manure management strategies that boost productivity on Québec dairy farms and reduce their emissions of greenhouse gases.

The IRDA team is monitoring the hydrology of the three main watersheds in Saint-Zotique.

The project consisted of monitoring the hydrology of the main watercourses flowing into Lac Boivin to determine their flow rates and sediment, nitrogen, and phosphorus inputs to the lake.

The purpose of this project was to develop a set of spatially referenced tools for watercourse managers and those in charge of planning sustainable, environmentally friendly improvements to water systems.

The objective of this project was to determine whether the addition of two types of organic fertilizers or biostimulants would produce more vigorous plants less subject to decline.

As part of an integrated pest control program, the company Les Serres Rosaire Pion & fils launched an innovative project on the use of flower strips in potted perennial production.

There is a great need to test green manure as a main source of nitrogen for potatoes as they help to maintain soil quality and control weeds.

Meeting nitrogen requirements mainly through the use of a highly stable form of fertilizer can minimize nitrogen losses, provide nitrogen amounts closer to the plant’s actual needs.

IRDA produced posters to help producers and extension agents choose pest and disease control strategies that promote the use of IPM.

This project helped to determine if there is a significant correlation between the number of adult spotted wing drosophila captured and yield losses observed in the field.

This project proposes ways of using legume intercrops to control vegetable pests (insects, diseases, and weeds) while increasing soil productivity and quality and economic yields.
