an interger used as seed for Random Number Generator.
a string specifying the deployment strategy: "MO" for mosaic of resistant cultivars, "MI" for intra-fied mixtures, "RO" for cultivar rotations, and "PY" for resistance gene pyramiding in a cultivar.
number of cropping seasons (years) to simulate.
number of time-steps (days) per cropping season.
a logical indicating if a video must be generated (TRUE, default) or not (FALSE).
A set of text files, graphics and a video showing epidemic dynamics.
In these examples on rust fungi of cereal crops, 2 completely efficient resistance sources (typical of major resistance genes) are deployed in the landscape according to one of the following strategies:
Mosaic: 3 pure crops (S + R1 + R2) with very high spatial aggregation.
Mixture: 1 pure susceptible crop + 1 mixture of two resistant cultivars, with high aggregation.
Rotation: 1 susceptible pure crop + 2 resistant crops in alternation every 2 years , with moderate aggregation.
Pyramiding: 1 susceptible crop + 1 pyramided cultivar in a fragmented landscape (low aggregation).
