BiOAD - Development of decision support systems to promote the use of biocontrol
Development of decision support systems to promote the use of biocontrol
  • PhD: Thomas PRESSECQ
  • Biocontrol agents are promising tools to reduce the use of chemical pesticides in agriculture. They represent one of the few means of intervention in organic farming, which makes the success of their use particularly important. Due to their special characteristics (living organisms in the case of microorganisms, object of this study), their deployment is more complex than applying chemical molecules. This can hinder their adoption and foster the variability of their efficacy. Taking this complexity into account would make their use more reliable. This complexity is difficult to envisage in simple product data sheets. Thus, to facilitate advice to farmers, it is necessary to develop decision support systems (DSS), integrating the biological properties of biocontrol agents, those of plant pathogens, and the characteristics of cropping systems. The objective of this PhD thesis is (1) to identify and prioritize the factors governing the efficacy of biocontrol agents, (2) to identify those that could be the subject of decision rules in crop system, (3) to develop a generic prototype of DSS and (4) to parameterize and evaluate a DSS for a specific combination (crop / biocontrol agent / disease) of interest to agriculture. This work will involve the conduction of surveys, a meta-analysis of scientific literature and biological experiments.
