Amphobotrys ricini, the causal agent of gray mold, is the most important plant pathogen of castor bean. As there are no effective control measures for gray mold, the objective of this study was to evaluate the progress of the disease on representative castor bean cultivars (BRS Energia, IAC Guarani, and IAC 2028) sown in October, November, and December in Paraná a state, Brazil. Field experiments were conducted under minimum tillage in the Instituto Agronômico do Paraná a Research Station in the 2010/11 and 2011/12 seasons. Evaluations of gray mold incidence and severity were initiated at the onset of first disease symptoms on castor bean bunches. Bunch weight was estimated. The weather conditions were favorable to gray mold epidemics in both planting seasons. A significant interaction between sowing dates and cultivar genotypes was found for the area under the disease progress curve of gray mold by incidence (AUGMI) and severity (AUGMS). Cultivar IAC Guarani sown in December 2010 and October 2011 had the lowest values of AUGMI and AUGMS. Highest values of AUGMI and AUGMS were estimated for cv. BRS Energia in both seasons. Although there were no significant interactions between sowing dates and cultivar genotypes, highest bunch weights were found with cvs. IAC Guarani and IAC 2028 in the 2010/11 season. However, there were no differences for bunch weights among cultivars in the 2011/12 season. Therefore, cultivar IAC Guarani is a suitable option for castor bean production in Paraná a state, combining lowest susceptibility and highest yields.
