A fork of cropsim designed to make using the EPIRICE model (Savary et al. 2012) for rice diseases easier to use. This version provides easy to use functions to fetch weather data from NASA POWER, via the nasapower package (Sparks 2018, Sparks 2020) and predict disease severity of five rice diseases using a generic SEIR model (Zadoks 1971) function, SEIR(). The original EPIRICE manuscript, Savary et al. (2012), which details the model and results of its use to model global epidemics of rice diseases, was published in Crop Protection detailing global unmanaged disease risk of bacterial blight, brown spot, leaf blast, sheath blight and tungro, which are included in this package.
