Weed control methods to reduce the number of viable seeds in the soil are limited in organic production. Biofumigation could be an attractive option for increasing the mortality of dormant seeds. Biofumigation uses plants naturally rich in glucosinolates (especially the cabbage family), which release toxic volatile compounds (thiocyanates and isothiocyanates) as they decompose. The aim of this project was to explore the potential of biofumigation for reducing weed seed banks and its long-term impact on weed communities. Two experiments were set up at the Organic Agriculture Innovation Platform in Saint-Bruno-de-Montarville, Québec. The first was a greenhouse study on four generations of weeds and the second was a three-year field trial.

This project aims to explore and experiment new approaches and ways to preserve, develop, and enhance the MRC’s bio-food sector, and reduce or eliminate the water deficit on the island.
Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
