Resumo(...) Loss is a function of the difference in the relative area under the disease progress curves (RAUDPC) among these crops multiplied by the effect of disease on bulking rate. RAUDPC calculation is based on integrating disease severity over the period of yield accumulation and weighing each chronological day by its relative contribution to host growth. Seventy-one epidemics of early blight or late blight that developed in Freeville, NY, where the model's parameters were estimated and 53 epidemics from other growing areas or from epidemics having both pathogens simultaneously in Freeville, were used as independent data sets for evaluating the predictions of the model (...)
