The swede midge has been the main pest of crucifers (cabbage family) in Québec since 2003. Its presence throughout the season, the difficulty of detecting the damage it causes, and its cryptic behaviour make controlling this pest very complicated. Organic producers currently rely on pest exclusion nets, which are expensive to use. It is important, therefore, to develop other effective ways of controlling this pest.
In conventional production, numerous insecticide sprays are sometimes required. The health and environmental risks associated with insecticide use and consumer demand for pesticide-free products are creating pressure to find other, less risky control methods.

Pest, weed, and disease control
In contrast to pesticide use, this method lowers health risks to humans and the environment.

The fungal pathogen Helminthosporium solani causes silver scurf, a disease that is hard to detect, both in the soil and on harvested potatoes.

This project aims to evaluate effective and economically viable control strategies for leek moth that are healthy for both humans and ecosystems.
Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.
