Research Projects

The hypothesis was that it should be possible to measure sap flow in apple trees and correlate it with soil water conditions and the weather.

The aim of this project was to leverage the efficiency of drip irrigation and splitting nitrogen inputs into multiple applications to reduce total nitrogen inputs per unit produced and provide better economic and environmental alternatives to conventional irrigation.

This project will compare the ability of various pheromone mixes to prevent male swede midges from locating females.

This online training platform will help improve technical support for Québec apple growers by furthering the training of new consultants.

Economic analysis of using flower strips around soybean fields to serve as a reservoir for aphid species attacked by Pandora neoaphidis.

The aim of this project is to determine the combined impact on fungicide efficacy of rain and the appearance of new leaves to more accurately identify how long treatments remain effective.

The main aim of this project is to test a bacterial detection technique developed in Austria that consists of quantifying inoculum carried by bees.

The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.

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.
