Etude de la variabilité des propriétés physiques et hydrodynamiques d'un sol argileux sous l'effet de conduites en protection intégrée contre les adv…

2015

Integrated weed management (IWM)-based cropping systems are of great interest due to their significant reduction of herbicide inputs by using a complex combination of agricultural techniques. The main objective of our work was to contribute to the environmental dimension of the multi-criteria evaluation of IWM-based cropping systems which were set up since 2000 on the experimental domain of the National Institute for Agronomical Research (INRA) to Bretenière (France). The variability of physical and hydrodynamic soil properties involved in the transfer of water through the vadose zone was studied for the 5 cropping systems present on the experimental site (1 reference cropping system and 4 …

The arbuscular mycorrhizal symbiosis a modulator of cadmium stress

2008

International audience; Ecosystems are submitted to various abiotic stresses, among which heavy metals represent major industrial pollutants. Cadmium (Cd), that has damaging effects on plant metabolism, occurs in agricultural environments through industrial pollution and human activities, including phosphate fertiliser and sewage sludge applications. Metal availability to plants can be modulated by soil microorganisms, such as arbuscular mycorrhizal (AM) fungi. In the present work, Cd effects on the model legume Medicago truncatula inoculated or not with the AM fungus Glomus intraradices have been studied at 3 levels: (1) plant biomass production together with green part chlorophyll quantif…

Le rôle des modèles pour l'évaluation multicritère et la conception multi-objectif de systèmes de culture pour la gestion des adventices

2013

Weeds are both harmful for crop production and important for biodiversity in agricultural landscapes. Moreover, we need to reduce herbicide use to limit environmental impacts. We therefore must design new cropping systems optimising all cultural techniques and reconciling agricultural production on one hand, herbicide reduction and biodiversity on the other hand. The objective of our study was to illustrate how to (1) develop models quantifying the effects of cropping systems on weed dynamics, (2) integrate interactions between weeds and other biotic components, (3) translate weed flora into a series of indicators of the impact on production and biodiversity, (4) use the model for multicrit…

Complémentarité entre expérimentations et réseau de fermes pour explorer des systèmes de culture à faible usage de pesticides

2013

Cropping system prototypes are assessed in long term experiments to test innovative strategies. The experiment conducted at the INRA-Dijon showed that Integrated Weed Management can be successful in controlling weeds. Environmental benefits and impacts on productivity and profitability were quantified. However, only a limited number of strategies can be explored in such experiments, and the generic value of the results might be questioned, notably regarding the adaptation of the systems to other contexts. Analysing data from farm networks provide additional knowledge, using the huge diversity of agricultural situations and cropping systems. The network ‘DEPHY-Ferme’ is part of the ECOPHYTO …

Fusariose du cyclamen : connaître, détecter et prévenir

2015

SPE Pôle IPM; Fusarium oxysporum est un champignon tellurique ubiquiste présentant une grande diversité de souches pathogènes et non pathogènes. Les souches phytopathogènes sont groupées en formae speciales selon leur spécificité d’hôte. Ainsi, la forma specialis cyclaminis (Focy) est responsable de la fusariose vasculaire du cyclamen. C’est le pathogène le plus destructeur sur cyclamen. Le pathogène, et donc la maladie peuvent intervenir à tout moment du cycle de culture causant d’importantes les pertes. Malheureusement, la détection préventive de Focy n’est pas possible, la lutte chimique inefficace et la résistance variétale inexistante. La lutte biologique apparaît comme l’alternative à…

Discussion on collaborative works on rare plants protection

2014

During the session, I presented the interest of studying rare plants and the need to assess the relative success of different conservation measures. Besides its rationale and the diverse benefits for agriculture, biodiversity and human heritage, I discussed the hassle of getting money to setup programs and get money from national and European agencies. Being sexy for decision-makers and explaining key questions for reviewers was illustrated by deciders’’ responses to three calls for public tender for research proposals in the area of agriculture and biodiversity. One proposal was for a European research grant on restoration of arable plant communities. Ten of the 52 eligible projects were a…

2014

National audience; Le séminaire « Gérer la santé des cultures : des variétés au paysage » exposera une vision de la complémentarité des leviers utilisables pour gérer la santé des plantes. On abordera aussi bien les résistances variétales que les pratiques agronomiques qui accompagnent leur déploiement. On fera également le point sur le renouvellement des méthodes de surveillance des bioagresseurs pouvant être mises en œuvre collectivement pour un gain notable d’efficacité. La première session sera consacrée à deux exemples de mise au point de nouvelles variétés porteuses de résistances génétiques, de leur découverte à leur caractérisation et à leur déploiement sur le territoire. Deux histo…
