Focus expansion in plant disease. IV. Expansion rates in mixtures of resistant and susceptible hosts

1990-07-01

Abstract excerpt

The radial expansion of plant disease foci in ideal (i.e., infinitesimally fine grained) mixtures of a susceptible and a resistant cultivar is described. If the only difference between the cultivars is in their susceptibility to disease, theory predicts that the radial velocity of focus expansion increases linearly with the logarithm of the fraction of susceptible plants. This hypothesis was tested in the field by...
