The objective of the project is to equip cranberry producers with phytoprotection in order to ensure the sustainability of the organic sector, which is the pride of the province, but also to reduce the impact on human health and the environment of interventions. phytosanitary measures by optimizing monitoring and intervention periods for the major crop pest: the cranberry leafroller. This insect, whose damage can cause a reduction in yields of up to 95% of the annual harvest, represents the main threat to the sustainability of the organic sector.

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.
