The out-of-soil cultivation of organic raspberries holds great market potential for Canadian berry growers. However, in order to address the attendant phytosanitary issues, research into cropping methods must be carried out and technologies adapted before the practice can be successfully implemented across Canada. The project will be carried out over a four-year period on experimental and on-farm plots that replicate conditions found in commercial facilities, which will facilitate the eventual transfer of knowledge to potential users. The first two activities to be undertaken will seek to boost the profitability of organic raspberry growing by scaling back costly bio-pesticide applications through the development of beneficial organism and sterile insect release practices. The proposed experiments reflect an approach based on the pooling of different types of knowledge rather than reliance on experiments conducted in isolation. The final two activities will seek to make the best use of organic nutrition for out-of-soil long cane raspberry production by optimizing a number of variables related to soil health, i.e., soil substrates, fertilization, and soil volume. This project directly addresses the needs of Canadian producers interested in growing out-of-soil organic raspberries in high tunnels in a profitable and competitive manner with a view to selling their product locally or to large retail chains.
From 2019 to 2023
Optimal water management, Fertilizer management, Pest, weed, and disease control
This major project will result in the development of a cost-effective and competitive protocol for growing organic rapsberries.

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.
