Most of Quebec's wild blueberry production is frozen. This allows large volumes of fruit to be harvested in a short period of time and sold throughout the year. Fresh blueberries are in a more precarious situation where the harvest period determines when they will be on the shelves of food chains. Ripening occurs at a time when the risk of frost increases. Increasing the consumption of fresh Quebec wild blueberries and improving the predictability of supply from one season to the next are priorities for the sector. To achieve this, harvests need to be spread out over a longer period of time to prevent an early frost event from sabotaging the crop. The risk of frost can be mitigated with different protection methods that have proven their worth for other crops. However, the feasibility, cost, risks and framework for successful adoption of this practice remain to be detailed for blueberries.
From 2020 to 2022
This project’s goal is to develop a large-scale inundative release method using the same trichogramma species employed in a previous project.
