Plant and Canopy Architecture Impact
on Disease Epidemiology and Pest Development

International Conference

July 1-5, 2012 - Rennes, France
The increase in agricultural production over the past fifty years is due to the improvement of yield potential of major crop cultivars, as well as to the massive use of plant health products. However, the current model of crop protection generates complex environmental, human health and economic problems, largely detailed in several instances.

Setting up and implementing alternatives to the 'pesticide only' approach implies to improve currently existing methods (Decision Support Systems, longer rotations, more robust cultivars, mixed crops), to assess their applicability in practice, but also to develop new knowledge that can be put to use in integrated and innovative crop protection and crop production systems.
To reduce the use of pesticides, innovative studies are developed to introduce the plant as the centre of the crop protection system. They aim at acquiring, structuring and exploiting new infor- mation about the plant in order to:
  • analyse how plant architectural traits modify the expression and development of disease epidemics and pest development,
  • define which of these traits (single or combined, at the plant or at the canopy scale) can reduce epidemic progress,
  • model simultaneously plant development and epidemic progress.
This conference focuses on an emerging scientific theme  "plant and canopy architecture as a driver of epidemic processes". Through its scientific and methodological coherence, it aims at overcoming disciplinary boundaries to gain new knowledge directly applicable to the elaboration of environmentally friendlier crop production systems.

The purpose of this conference will be to determine:
  • the role of plant and canopy architecture on disease and pest development,
  • the role of canopy architecture on disease and pest development through the modification of the canopy microclimate and the physiological status of the organs or the whole plant,
  • the role of plant genetics to control architectural traits contributing to disease/pest reduction,
  • the impact of these modifications on yield losses,
  • the possibility to combine the architectural traits and other disease control methods (resistance, cultural practices) to reduce the use of pesticides.
The participation of scientists from several complementary scientific communities is expected to develop a true multidisciplinary approach: Plant Epidemiology, Entomology, Agronomy, Plant and Crop PhysiologBy, Bioclimatology, Plant Genetics, Mathematical Modelling .
