Performances of pesticide-free agroecological cropping systems: the CA-SYS platform
Meeting the challenges of current agriculture requires the development of innovativecropping systems with high environmental, economic and social performances. Agroecologyseeks to optimize the services provided by cultivated and wild biodiversity to reduce thereliance on external inputs while maintaining/increasing cropping system sustainability.Maximizing the delivery of ecosystem services from biodiversity requires an in-depth redesignof production systems considering in-field management as well as ecological infrastructuressurrounding the fields. An agroecological system experiment aims to design and assesscropping systems, the spatio-temporal arrangements of these cropping systems andec…
Mobiliser les agroéquipements et le numérique pour des systèmes de culture sans pesticides
Chapitre 6 Disponible gratuitement en ebook; International audience; Les agroéquipements et le numérique sont des leviers essentiels pour développer des systèmes de culture sans pesticides. Des innovations en matière de précision d’exécutionet d’adaptabilité des équipements sont attendues. En parallèle, le développement des capteurs va permettre d’améliorer la surveillance des bioagresseurs, mais égalementcelle de l’ensemble du système de culture et de son environnement. Les capteurs, associés aux nouvelles technologies de l’information, pourront également contribuer àl’émergence de filières sans pesticides et facilitant la traçabilité du champ à l’assiette. Des questions vont néanmoins se …
Accompagner les réseaux DEPHY-FERME et DEPHY EXPE dans la caractérisation de l’effet des systèmes de culture sur la flore adventice
To characterize weed pressure in agricultural fields of the DEPHY Ecophyto networks, the "weeds" working group of the CASIMIR project, helped by crop and weed experts working for the french crop institutes, developed two methods (CASIMIR DEPHYFARM and CASIMIR DEPHYEXPE) to survey weeds in main crops. The objectives of these methods are: (i) with shortterm concern, assess the efficacy of farming practices to manage weeds within the crop season, (ii) with longterm concern, assess the effect of cropping system (farming practices and crop sequence) on the dynamic of the weed communities. The CASIMIR DEPHYFARM method is based on walk away surveys made within a 2000m² reference plot where t…
Co-design and test of biodiversity-based pesticide-free Conservation Agriculture in the long-term CA-SYS platform in France
The French National Institute for Agricultural Research (INRA) has established an ambitious experimental infrastructure (the CA-SYS platform) in autumn 2018 after 5 years of co-design with farmers, crop advisors and researchers. CA-SYS covers an area of 125ha divided into 42 fields. The originality of CA-SYS is that it is explicitly conceivedfor the design and evaluation of biodiversity-based and pesticide-free agroecological systems across agriculturallyrealistic scales. An agroecological system will comprise a matrix of fields of one (or a few) cropping systems over anumber of years interacting with adjacent semi-natural habitats (hedges, grass margin strips, flower strips). Thisspatio-te…
Field testing of IPM-based cropping systems: a diversity of experimental approaches in Europe
International audience; Integrated Pest Management (IPM) emphasizes physical and biological regulation strategies to control pests while reducing the reliance on pesticides. It is often based on combinations of control measures, because each available alternative measure might have a moderate efficiency. Field experiments are required to analyse the interactions between control measures, and to evaluate the sustainability of IPM-based cropping systems (CS). A network of European agronomists managing field experiments at the CS level was set recently, aiming at sharing data and expertise to enhance our knowledge on IPM. Comparing methodologies highlighted a diversity of approaches in CS desi…
