Abstrakt: Irisbulbs and Crocuscorms were planted at two planting dates in sandy soil infested with Pythiumspp. At monthly intervals during the growing season root rot infection was assessed over 3 consecutive years and disease development curves were predicted for both crops. The disease development was remarkably different for Irisand Crocusand the curve shape was determined by the crop rather than by the Pythiumspecies. Planting date had a significant effect on disease development in both crops. No correlation was found between disease development and soil temperature.
