The goal of this project was to document the impact of climate change on fruit crop pests and diseases in Québec. Lists were drawn up of pests and diseases that are likely to change and exotic invasive species that will threaten four fruit crops due to climate change. This allowed us to recommend plant protection strategies that decision makers and producers need to develop or adopt.
For four fruit crops of major economic importance in Québec (apples, cranberries, strawberries, and raspberries):
From 2016 to 2018
Pest, weed, and disease control
This project will help prepare berry growers for the emergence of new pests.

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.

Exclusion nets have proven to be effective against nearly all of these insect pests, which means that it’s possible to develop apple growing practices in Québec that are not only neonicotinoid free, but also devoid of all pesticides (including acaricides, given that mite problems are a consequence of broad-spectrum insecticide use). Although the net exclusion microsystem studied in Québec since 2012 has demonstrated its effectiveness in controlling insect pests, some issues remain to be studied before it can be unreservedly recommended. Among these are the handling times for the nets, i.e., installation/removal and opening/closing, and the system’s profitability and durability over the long haul for various cultivars.
