The proportion of resistant hosts in mixtures should be biased towards the resistance with the lowest breaking cost
Fig 5
Prevalence of the disease (P) at equilibrium as a function of the proportion of resistance 2 (p), when varieties are not epidemiologically interchangeable (c1 ≠ c2 < 0.5).
Parameter values: R = 7, ρ = 0.8, and ν = 1.
