Root rot of pea: characterization and biocontrol of the soil-borne disease complex including Aphanomyces euteiches
Pea root rot is an increasing constraint in most of intensive pea cropping areas across the globe. The pathogenic complex responsible for the disease is composed of soil-borne fungal and oomycete pathogens such as Fusarium solani, F.oxysporum, F. avenaceum, F. culmorum, Rhizoctonia solani, Thielaviopsis basicola, Ascochyta pinodella, Pythium spp., Aphanomyces euteiches and probably others not yet identified. The diversity of their ecological and pathogenic properties can explain the worldwide dispersion of the disease and the absence of chemical, agricultural or genetic control tools. My research program aims at characterizing the parasitic consortium occurring in the North of France and at…

Pea root rot diseases : characterization and biocontrol of the disease complex including Aphanomyces euteiches.
Root rots in peas are a major concern in most growing regions around the world. The disease is caused by a parasitic complex made up of many species of soil-borne fungi and oomycetes. In France, the main pathogen involved until recently was the oomycete Aphanomyces euteiches. The identity of the other components of the parasitic complex and their respective contributions to the disease have not been investigated. No control method is currently available to effectively control the disease, apart from a predictive biological test questioned by some users. However, this test allows the avoidance of infested plots, which furthermore limits the multiplication in soils of A. euteiches, i.e. the m…
Les pourritures racinaires du pois potager, caractérisation et biocontrôle du complexe parasitaire d’origine tellurique incluant Aphanomyces euteiches
Pea root rots are a major concern for pea growing regions around the world. The disease is caused by a parasitic complex composed of many species of fungi and oomycetes of soil origin. In France, the main pathogen is the oomycete Aphanomyces euteiches. The identity of the other components of the parasitic complex and their respective contributions to the disease have never been investigated. No means of control is currently available to effectively control the disease except for a predictive bioassay that is questioned by some users. However, this test allows the avoidance of infested plots, which limits the multiplication of the major pathogen A. euteiches in the soil. In this context, the…
