Dispersal patterns simulated in virtual 3-D canopies in cultivar mixtures with contrasting canopy structure. Drop interception (A) was expressed as a proportion of total raindrops per m² of leaves. Inoculum interception (B) was expressed as the number of spore-carrying droplets per incoming raindrop and per m² of leaves. Diseased leaves of susceptible plants constituted most of the inoculum source and corresponded to lower leaves (leaf 4 and 5). Error bars correspond to the s.e. obtained with four simulations for each treatment.
