Résistance du vulpin aux herbicides. Son importance et sa répartition en Côte d'Or
2006
BlACKGRASS lN WHEAT: A MAP OF HERBICIDE RESISTANCE Since the years 1990, the spread of herbicide resistance in wheatis more and more important within weed species as blackgrass (Alopecurus myosuroidesHuds,). Resistanceto the fenoxaprop-P-ethyl within blackgrass population wasfirst was detected in the Côte d'Or departement. ln this context, a map of the herbicide resistance of blackgrass was undertaken at the scale of this departement. 149 fields were used for this study with for each an agronomic investigation and harvests of blackgrass seeds. Almost the whole of the populations of blackgrass tested present at least 50% of plants resistant to fenoxaprop-P-ethyl, and 53% and 9% of these popu…

Medicago species affect the community composition of arbuscular mycorrhizal fungi associated with roots
2007
National audience; The symbiosis between plants and arbuscular mycorrhizal fungi (AMF) is ancient and involves 80% of terrestrial plant families. The symbiotic association between AMF and plants was described to be non specific. However, AMF were reported to influence plant community diversity and productivity. On the other way, the effect of plant genotypes belonging to closely related species on AMF diversity has not been explored so far. The aim of this work was to assess the impact of four different Medicago species, M. laciniata, M. murex, M. polymorpha and M. truncatula cv. Jemalong J5, on the composition of AM fungal community, when cultivated in a silty-thin clay soil (Mas d’Imbert,…
Review of factors influencing the success or failure of biocontrol: technical, industrial and socio-economic perspectives
2010
Communication orale au 11. IOBC-WPRS Meeting of the working group "Biological control of fungal and bacterial plant pathogens". Climate change: challenge or threat to biocontrol?, 2010/06/07-11 ; Graz (AUT).; International audience; Although their role in plant health management is still quite modest, ever increasing expectations are placed on biocontrol agents for the complementation or replacement of pesticide use. Despite decades of research and more than 12,000 scientific papers on biological control of plant diseases, little more than 14 microbe-based commercial products are presently registered for use against diseases in the European Union. Through a review of published scientific li…
