Fig. 4.

Simulated raindrop and inoculum interception by resistant and susceptible virtual plants in a cultivar mixture as a function of virtual plant height of each cultivar making up the mixture. Each point corresponds to one simulation with a determined height of virtual plants of one of the cultivars making up the mixture. The reference was a homogeneous cultivar mixture with a resistant and a susceptible cultivar, both of standard plant height (approx. 80 cm), at the flowering stage. Plant height is expressed as a proportion of the reference plant height. In (A) and (C), the size of the resistant cultivar varies, while the size of the susceptible cultivar is fixed with two different heights: reference height (solid line) or twice the reference height (dotted line). In (B) and (D), the size of the susceptible cultivar varies, while the size of the resistant cultivar is fixed with two different heights (solid line: reference height, dotted line: twice the reference height).
