Spatial factors in the epidemiology of black pod rot caused by Phytophthora sp.
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.
