Results for Fruit production
Strawberry field
2015-2017 • Fruit production

Developing a cropping system that focuses on improving soil health to restore the yield potential of matted row strawberry fields with a history of strawberry decline

A cropping system based on adding organic matter through soil amendments and organic fertilizers can restore soil health and strawberry yields by limiting the occurrence of disease symptoms.

Blueberries
2016 • Fruit production

Detecting spores of Pucciniastrum geopertianum, the fungus that causes blueberry witches’ broom rust

The aim of the project was to determine whether the witches’ broom symptom on blueberries is really caused by the rust Pucciniastrum geopertianum, which attacks balsam.

Exclusion nets
2014-2018 • Fruit production

Exclusion nets for organic apple production in Eastern Canada

The aim of this project was to test the general hypothesis that exclusion nets, when properly used, can prevent attacks by most apple pests and reduce disease incidence with no major adverse effects on fruit quality.

Spotted Wing Drosophila
2016-2019 • Fruit production

Control strategies to reduce the impact of the spotted wing drosophila

This project aims to promote a biocontrol solution by testing a complex of natural enemies that attack the spotted wing drosophilia at different development stages.

Exclusion net
2017-2019 • Fruit production

Exclusion nets made from biobased polymers

The purpose of this project is to test the general hypothesis that biobased polymers can be used to replace fossil-fuel-based products and reduce the use of pesticides without increasing GHG emissions.

Plasticulture

Banded controlled-release and conventional fertilizer in horticultural production under plastic mulch

The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.

Plum curculio
2015-2017 • Fruit production

Attract and kill strategies for control of the plum curculio in conventional and organic apple orchards

An attract and kill technique to control plum curculio was recently proposed by U.S. researchers, but it is very little used in orchards and virtually unknown in Québec.

Blueberries
2015-2019 • Fruit production

Sound water management for lowbush blueberries under fluctuating and changing climatic conditions

Using sound irrigation management to control frost and water stress in lowbush blueberry helps stabilize yield while minimizing environmental impacts.

Mullein Bug
2016-2019 • Fruit production

Selection, mass rearing, and field efficiency of a predaceous strain of mullein bug

The goal of the project is to select a strain of the mullein bug to control two spotted and red spider mites when populations tend to explode.

Cranberries
2016-2018 • Fruit production

Adapting fruit crop pest and disease control to climate change

The goal of this project was to document the impact of climate change on fruit crop pests and diseases in Québec.

Strawberries
2015-2017 • Fruit production

Effects of various irrigation strategies on nutrient uptake in organically grown June-bearing strawberries grown in beds covered with black plastic mulch

The project was conducted at IRDA’S Organic Agriculture Innovation Platform. Strawberries (Cleary cultivar) were produced in beds covered with black plastic mulch.

Blueberry Field
2015-2016 • Fruit production

Productivity of healthy looking plants that have never received nitrogen fertilizer and that are located in a blueberry field infected by stunt disease

In highbush blueberry fields where stunt disease has been detected, plants that have never received nitrogen fertilizer are more vigorous and homogeneous than plants that have received nitrogen fertilizer.
