Full textPectobacterium atrosepticum is a major pathogen of Solanum tuberosum that causes tuber soft rot and potato plant blackleg that are responsible for important economic losses. As methods of control are limited to avoidance of contamination and pathogen expansion ability is high, potato industry – notably Comité Nord – promotes researches that aim at finding efficient control strategies. Concerns about environment preservation in European agricultural policies has incited us to detail our knowledge of this telluric pathogen and of the microflora associated to potato roots in order to develop a new control strategy environmentally respectful. As many other phytopathogens, P. Atrosepticum virulence is controlled by a quorum sensing regulation system based on N-Acyl homoserine Lactone (N-Acyl-HSL) signalling molecules. The psychrotrophic bacteria P. Atrosepticum 6276 uses N-3-oxo-L-octanoyl-homoserine lactone as major N-Acyl-HSL. Mutation of the unique NAcyl- HSL synthase gene leads to an avirulent phenotype. The N-Acyl-HSL production occurs between 2 key events of pathogenicity which are cellular multiplication and maceration. As bacterial growth, N-Acyl-HSL production is observed at least from 8 to 28°C and is optimal production of N-Acyl-HSL is observed at 24°C. Considering the importance of N-Acyl-HSL for pathogenicity, we develop a biocontrol method using NAcyl- HSL degrading bacteria. Potato root associated microflora and 2 model strains belonging to Pseudomonas and Rhodococcus genera were used as a source of biocontrol agents

Full textThe adverse effects of pesticides on health and the environment are well known and different regulations aim at decreasing their use in the agricultural sector in France and Europe. However, this use does not decrease in practice. Agriculture is as of yet characterized in academic literature by a technological lock-in on an intensive use of pesticides. Analyses of technological lock-in have shown that one solution is to produce knowledge on alternative techniques. In this regard, agricultural advisory services have a key role. These services have, nonetheless, undergone profound organisational transformations in European countries, leading to a greater pluralism of agricultural service providers.This PhD research questions the performance of farm advisory services and their capacity to produce knowledge on alternative farming practices that does not require an intensive use of pesticides. This work is based on advances from institutional economics dealing with knowledge intensive business services (KIBS). It presents a conceptual and methodological framework developed to analyse the diversity of service suppliers, their partnerships and their conception of the performance of advisory services. The research draws on case studies in the French potato seed industry

Adaptation du modèle SIPPOM (Simulator for Integrated Pathogen POpulation Management) au pathosystème." Thesis, Toulouse, INPT, 2012. http://www.theses.fr/2012INPT0147/document.
Full textPotato late blight caused by the pathogen Phytophthora infestans is one of the most dreaded diseases to this culture. So far, chemical control is the most widespread method used against the pathogen. In turn, the amount of fungicides used to control this disease makes potato the crop with the highest Treatment Frequency Index of all arable crops. The use of resistant varieties, including specific resistance genes, has also demonstrated an effective limitation of injuries that this disease can cause. Still, specific resistances lack durability as there is an average span of 4 years before the emergence of a resistance breakdown phenomenon by more virulent strains. It is therefore necessary to develop control strategies that combine a set of methods (genetic, cultural, physical and chemical) to meet agronomic, environmental and socio-economic criteria. A model named SIPPOM (Simulator for Integrated Pathogen POpulation Management), was developed to address these issues for the control of phoma stem canker on oilseed rape. The present work consisted in adapting the generic structure of SIPPOM for the integrated control of potato late blight by designing specific sub-models using existing models or specifically developed models. A crop model (Spudgro), an epidemiologic model (Guntz-Divoux/Milsol), a damage model (Shtienberg's model) and a dispersal function (Scherm's model) were selected in the literature, adapted, and embedded in SIPPOM's generic structure. This set of sub-models led to an operational prototype of SIPPOM-de-terre under the RECORD modelling platform. A new model, named VOLPONE, was designed to simulate potato volunteer dynamics in a field or on a waste pile. This model permits to simulate inoculum sources at the territory scale under the influence of climate and cropping practices. The predictive quality of the damage model was assessed with data generated in specific field experimentations and proved to be good. Simulation examples produced with the first prototype of SIPPOM-de-terre illustrate the capacity of the model to represent epidemiological dynamics at the field scale or at a small regional scale under the influence of cropping practices and climate. However, further work is required before to totally achieve the design and the implementation of SIPPOM-de-terre under the modelling platform RECORD. The conducted study illustrates the genericity of the model SIPPOM and produced knowledge, references and tools for the integrated management of the disease. The outputs of this work will help design integrated, collective and durable control strategies of potato late blight
