Autre titre : Facteurs spatiaux dans l'épidémiologie de la pourriture brune des cabosses due à Phytophthora sp.

Abstract : Early screening for resistance to Phytophthora sp. is efficient, notably using leaf discs. However, a field assessment under natural infection conditions remains necessary to validate results. Infestations display spatial effects on a study plot scale. Spatial heterogeneity therefore has to be taken into account in field assessments. (Résumé d'auteur)
