L’agriculture de précision au service de la transition : comment réduire drastiquement et efficacement l’usage des pesticides ?
L’agriculture est aujourd’hui confrontée à plusieurs défis majeurs résultant de plusieurs facteurs d’ordre aussi bien environnemental que socio-économique. L’un des plus importants étant notamment celui d’augmenter significativement sa production à l’horizon 2050 pour être en mesure de nourrir une population mondiale croissante, tout en préservant l’environnement. Autrement dit, satisfaire les besoins alimentaires des générations présentes sans compromettre la capacité des générations futures à satisfaire les leurs. Face au développement de souches de plus en plus virulentes des maladies phytopathologiques et à la résistance de certaines de ces maladies aux effets des pesticides, il est plus qu’important d’accélérer le développement d’une agriculture raisonnée reposant sur des traitements phytosanitaires pertinents et opportuns.
Le colloque L’agriculture de précision au service de la transition vise ainsi à être ce cadre d’échanges et de partages d’expériences autour de thèmes variés. Ces derniers incluent les récentes recherches scientifiques et technologiques en agriculture de précision et les facteurs d’adoption de ces technologies. Il ne faut pas oublier non plus l’utilisation et la valorisation des données, de plus en plus nombreuses et diverses dans un monde numérique, et les différents défis liés à une transition rapide vers une agriculture numérique/de précision durable.
Autant de sujets qui, sans nul doute, permettront de « prendre le pouls », en temps réel, des experts participant au colloque sur toutes ces questions d’actualité.
Le colloque sera dispensé en français et en anglais (avec une traduction simultanée vers le français pour ceux qui le désirent).
Version Anglaise
Modern agriculture faces several major challenges including a substantial increase in agricultural production by at least 50% by 2050 to feed the growing world population while preserving the environment. That is, feeding present generations without compromising the future. Given the development of increasingly virulent strains of plant diseases and the resistance of some of these diseases to agrochemicals, it is crucial to develop integrated plant protection strategies for effective and timely phytosanitary treatments to achieve sustainable and profitable farming activities.
The colloquium "Precision farming at the service of transition" aims at promoting and encouraging scientific debates and sharing of experiences around various themes including recent scientific and technological research in precision agriculture and the factors involved in adopting these technologies. We should also not forget the use and development of data, which is increasingly numerous and diverse in a digital world, and the various challenges linked to a rapid transition to sustainable digital/precision agriculture.
All these topics will undoubtedly allow the experts participating in the conference to “take the pulse”, in real-time, of all these current issues.

” The original tool for disease severity assessment: status of visual estimation”
Knowledge of the quantity of disease is crucial to many endeavors in plant pathology and related disciplines (for example, to understand the impact on yield loss). Historically, all plant disease assessment was performed by visual estimation. Even in 2022, the majority of studies rely on individuals to correctly detect disease, and subsequently identify and quantify it for both estimates of incidence and severity, where incidence is the proportion of units diseased, and severity is the quantity of diseased perceived on the unit. Incidence is an easier metric to quantify as it is a yes/no response. Severity, when based on the proportion or percentage of the unit diseased can be more challenging to estimate visually. Since the first attempt by Cobb in 1882 to quantify disease severity, there have been substantial advances in understanding error in visual plant disease severity estimation, and the development of new methods and tools as aids to improve the accuracy of visual estimates for individual raters and among raters. These will be discussed, best-operating practices for plant disease estimation presented, and the future role of digital, sensor-based technology acknowledged.

” Precision agriculture – challenges and opportunities for plant bacteria and viruses management”
Plant pathogenic bacteria and viruses are challenging pests in plant protection. There is a lack of direct control measures. Yet, precision agriculture is offering new tools and approaches for improving the management of those diseases. Recent innovations in the early field detection of plant diseases, the assessment of their spatial distribution will be reviewed. A focus on quarantine diseases like Xylella fastidiosa, Xanthomonas citri pv. citri or Huanglongbing will be given. Emerging surveillance approaches, as well as participatory approaches like the application appi.be will be advertised. The presentation will also be the opportunity to underline the challenges lying ahead of the wide-scale implementation of precision agriculture in this field.
