Fig. 6.

Simulated vertical distribution of inoculum interception within cultivar mixture canopies as a function of the distance to the main inoculum source. The graph shows the amount of inoculum intercepted per leaf area, by a determined leaf layer as a function of height difference with the main inoculum source (leaves 4 and 5 of the susceptible cultivar). Points correspond to simulations involving changes in cultivar height within mixtures with unchanged leaf area index. Each point corresponds to one leaf layer of one cultivar in one simulation. Leaf 1 (L1) corresponds to the top leaf or flag leaf. The curve corresponds to a model fitted for positive distances to the inoculum source: log(intCD) = 25.5 − 7.9 × (dInoc + 1.5) (R² = 0.84) with ‘intCD’ the number of intercepted contaminated droplets per raindrop and per m² of leaves and ‘dInoc’ the distance (height) to the inoculum source.
