Fig 1.
Proportion of recipient baits colonized by Rhizoctonia solani upon saprotrophic spread at (A) 10 mm, (B) 12.5 mm and (C) 25 mm after treatment with Monceren® L (pink lines) or tap water (blue lines).
Different letters indicate significant differences in the proportion of colonized baits (P-value < 0.05, Wald test).

Histogram describing the posterior distributions of the parameters of the saprotrophic spread model.
Fig 3.
Saprozone dynamics for saprotrophic spread of Rhizoctonia solani, describing the change in the probability colonization for a bait placed at a given distance from a mycelium disc and after a given time of exposure.
Circles indicate data observed in the placement experiments.
Fig 4.
Effect of fungicide treatment on pathogen infectivity.
Bars show the mean cumulated incidence at harvest (i.e. 30 days after sowing); dark and light grey refer to the type of symptom: damping-off and tuber necrosis, respectively. The analysis of deviance using a Wald chi-square test shows no significant differences between treatments.
Fig 5.
Proportion of recipient baits colonized by Rhizoctonia solani upon pathogenic spread at (A) 25 mm, (B) 50 mm and (C) 75 mm after treatment with Monceren® L (pink lines) or tap water (blue lines).
Different letters indicate significant differences in the proportion of colonized baits (P-value < 0.05, Wald test).

Fig 7.
Saprozone dynamics for pathogenic spread of Rhizoctonia solani, describing the change in the probability of colonization for bait placed at a given distance from a mycelium disc and after a given time of exposure.
Circles indicate data observed in the placement experiments. Data were fitted to the model.
