To reduce Fusarium Basal Rot caused by Fusarium oxysporum f.sp. cepae (Foc) through crop rotation, plant species should be selected based on Foc multiplication in their roots. Foc multiplication rates in 13 plant species were tested in a greenhouse. All plant species enabled Foc multiplication. The lowest Foc levels (cfu g−1 dry root) were found for wheat, sunflower, cowpea and millet, the highest for black bean. The highest Foc levels per plant were calculated for sudan grass. These data were used to calibrate the model Pf=Pi/(α+βPi) relating final (Pf) and initial (Pi) Foc levels in the soil. The rate of population increase at low Pi (1/α) was highest for onion and black oat and smallest for sunflower. The pathogen carrying capacity (1/β) was highest for black oat and black bean, and lowest forwheat, cowpea and foxtail millet. Foc soil population dynamics was simulated for crop sequences by concatenating Pi-Pf values, considering instantaneous or gradual pathogen release after harvest. Different soil Foc populations were attained after reaching steady states. Foc populations in the sequence onion ?foxtail millet - wheat ? cowpea were 67 % lower than in the sequence onion ? sudan grass - black oat - black beans. In this work, by combining detailed greenhouse experiments with modelling, we were able to screen crops for their ability to increase Foc population and to explore potential crop sequences that may limit pathogen build-up. © 2013 KNPV.  aDINÁMICA DE POBLACIONES  aFUSARIUM  aMODELOS DE SIMULACIÓN  aRELACIONES HUÉSPED-PARÁSITO1 aDE VRIES, M.1 aTER BRAAK, C.J.F.1 aVAN BRUGGEN, A.H.C.1 aROSSING, W.A.H.  tEuropean Journal of Plant Pathology, 2013gv.137, no.3, p.545-561.
