Spotted wing drosophila egg
2015-2017 • Fruit production

A study on the link between spotted wing drosophila populations, crop damage, and yield losses

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.

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.

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.

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.

Net
2015-2018 • Fruit production

Repellent properties of exclusion nets used for the control of leafroller and stink bug pests of apples

The aim of the project was to measure the effect of certain natural repellents that can be used on different types of exclusion nets.

Strawberries
2014-2018 • Fruit production

Developing a cropping system for organic strawberries

In a high density strawberry crop grown in sod covered with plastic mulch, evaluate the toxicity of bioinsecticides for controlling tarnished plant bugs and strawberry blossom beetles and of bioherbicides for controlling weeds in and between crop rows.

Tephritidae Fly
2014-2017 • Fruit production

Developing a sprayable attracticide to control tephritid flies in fruit production

The aim of the project was to test a series of attracticides that can be mixed and applied with regular sprayers with no additional specialized or expensive equipment or modifications required.

Apple Leafculing Midge
2014-2017 • Fruit production

Variable economic injury for the apple leafcurling midge and modelling of population abundance of this emerging pest

The apple leafcurling midge is a new apple pest in Québec. The aim of the project is to explore the pest’s phenology, establish variable economic injury thresholds, and incorporate the results into a phenology model in CIPRA.
