Research and/or project statements
My projects consist in detecting the presence of herbicide-resistant weeds and explaining the mechanism that the plant uses to survive the herbicide treatment. With this information, we develop genetic tests (molecular markers) which make possible the rapid detection of identical cases. We also study weed populations in order to better understand and possibly act on field implantation. This work is in line with the sector strategy in several ways. By its innovation, it allows to be more competitive in the external markets because it reduces the cost of inputs (herbicides) and therefore the cost of production. These tools, which provide rapid knowledge of resistance cases, mitigate risks and prevent unnecessary use of herbicides while encouraging the development of farming methods that will produce better results using resources with more efficiency.
