A foliar disease simulation model to assist the design of new control methods against black leaf streak disease of banana

•We built a foliar disease mechanistic model to simulate BLSD on a banana plant.•The model couples perennial host growth and complex pathogen epidemic cycle.•We present the Bayesian inference of the most influent pathogen parameters.•Model evaluation suggests realistic predictions of disease dynamics.•Simulations allow identifying disease control using plant resistance and plant growth.
