I-Weed Robot : un robot autoguidé pour un désherbage localisé

2013

We present the development of an autonomous robot, called I-Weed Robot (Intelligent Weed Robot), which aims at reducing herbicides in crop fields (maize, sunflower…). Using a high precision positioning signal (RTK) to locate the robot in the field, a Kalman filter and a proportional-integral-derivative controller (PID controller) allows adjusting the orientation and the speed of the robot depending on a predefined trajectory. As for the specific spraying system, a commercial system is used (weedseeker, Trimble) where the plant detection is obtained by an optical sensors just before to spray specifically on them. The performance of the guidance algorithm using numerical simulations (virtual …

2013

Soil is hosting a tremendous microbial diversity playing a key-role in a number of soil ecosystemic services including nutrient cycling and filtering. ln the European Soil Framework Directive pesticides are clearly marked as one of the major threats for soil biodiversity and functioning. ln orcier to guarantee minimum effects of pesticide application on soil microbes, pesticicleregistration at EU level (Regulation 2006/388) consiclers the toxicity of pesticides ontci non targefsoil microbes by relying on carbon- and nitrcigen-mineralization tests (OECO 216, 217). However tnese tests do not provicle a comprehensive assessment of pesticides onto soil microbes.-ECOFUN-MICROBIODIV was a project…

Establishment of Petunia hybrida as model for studying mycorrhiza-induced resistance

2012

Root pathogens play an important economical role in the production of vegetable and ornamental plants. They cause high losses especially in green house production and are difficult to combat by conventional methods, because the use of pesticides in soils or substrates is limited. The application of arbuscular mycorrhiza could be an alternative as mycorrhizal plants generally showed higher resistance against various soil-borne pathogenic fungi. The success of the inoculation is, however, not predictable and mechanisms behind the protective effects are largely unknown. The ornamental crop Petunia hybrida is among other solanaceous plants confronted with attack by root pathogens and was theref…

La biodiversité des sols au service d'une production agricole et d'une société durable

2019

Les sols sont à la base de nombreux services indispensables pour le développement et l’avenir de notre société. Ils sont le principal support de nos constructions et de notre production alimentaire et représentent aussi un puit de carbone capable de participer à la mitigation des changements climatiques. Leur surexploitation agricole, urbaine et industrielle, depuis le début du XXème siècle, a mené à une dégradation importante de leur qualité et donc des services associés. Historiquement, les géologues, les pédologues et les agronomes ont développé une expertise et des capacités de diagnostic de la qualité physique et chimique des sols et confirment l’impact négatif de certaines pratiques d…
