Description
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. The system was adapted specifically to conditions in Eastern Canada and a water barrier treatment added (depending on the results) to protect against apple scab.
Objective(s)
- Measure the effects of this protection system on fruit quality and profitability in the orchards’ geographic and climatic context (humid climate east of the Rockies)
From 2014 to 2018
Project duration
Fruit production
Activity areas
Pest, weed, and disease control
Service
IRDA helps Québec growers adopt eco-friendly tools.
Partner
