Experimentations to evaluate spatial strategies at the scale of a production basin to control Black leaf streak disease (BLSD) is difficult to implement. Modelling is a key approach to identify innovative scenarios to reduce the use of pesticides while efficiently and sustainably controlling the disease. To achieve this aim, we assess the efficacy of strategies directly based on fungicide applications or based on the deployment of resistant cultivars. For that, we adapted a published spatially-explicit model to simulate BLSD epidemics in a real 300-ha agricultural landscape of Costa-Rica. More than 11,000 simulations of strategies are undergoing and the best scenarios will be identified to be further tested in the field.
