Introduction du séminaire. Le projet ANR Peerless : viabilité d’une gestion écologique renforcée de la santé des plantes dans les paysages agricoles
2017
Prod 2017-344a SPE équipe EA GESTAD INRA; International audience; L’enjeu du projet PEERLESS (Appel d’offre ANR agrobiosphere, 2012) est de proposer une gestion viable des populations de ravageurs dans les agroécosystèmes par une approche intégrative combinant différentes échelles spatiales, des cultures pérennes et annuelles et les interactions trophiques entre plusieurs ravageurs et leurs ennemis naturels. La régulation des bioagresseurs par les auxiliaires naturellement présents dans les cultures est le service ecosystèmique que l’on souhaite renforcer afin de diminuer la dépendance des systèmes de production agricole aux pesticides. Bien que ces auxiliaires des cultures soient souvent m…
Gérer l’ambroisie à feuilles d’armoise en agriculture biologique

Managing common ragweed in organic agriculture Common ragweed (Ambrosia artemisiifolia L.) is an invasive plant native to North America, capable of developing rapidly in many environments: agricultural fields, roadsides, construction sites, wastelands, riverbanks. Pollen, emitted at the end of summer, causes strong allergic reactions in sensitive people (rhinitis, asthma, etc.). It is also a threat to agriculture, as this annual plant can cause significant yield losses if it is not controlled. A study was conducted to analyze the practices of organic farmers in arable crop systems to control ragweed, as well as their level of knowledge of this plant according to their location. The results …
Mise en évidence du rôle de la diversité dans la dynamique des communautés d'adventices et des interactions adventices/cultures
2020
The main challenge of 21st century agriculture is to provide sufficient food for a growing to identify cropping systems which maintain crop productivity, minimize reliance on synthetic herbicides and nitrogen fertilizers, and promote weed diversity. We hypothesized that cropping system diversification, either at the annual scale through the introduction of cover crops, or at the plurennial scale through a diversification of the crop sequence and associated weed management tools, could be a viable means to reach these objectives. More specifically, we hypothesized that cropping system diversification could (i) contain weed abundance and thereby, allow a reduction of herbicide use and an incr…
INFLOWEB : un site pédagogique sur les adventices pour aider à leur gestion intégrée
2013
INFLOWEB is a website that collects, summarizes and promotes useful knowledge to help weed management. This educational tool was developed in 2012 by CETIOM, ACTA AgroSup Dijon ARVALIS‐Institut du végétal, FNAMS, INRA, ITAB and ITB, with financial support from the Ministry of agriculture. The website aims to change the farmers weed management relying on an integrated approach of the weed flora. This paper presents the INFLOWEB site and discusses the results of a national survey on the prevalence and abundance of major weeds in crops. The survey was sent in 2011 to advisors, technicians and agronomists.
