Abstract

A report is given on host plants, distribution, damage and importance of Sclerotinia minor in the southern Pampas and northern Patagonia regions (Argentina). Spontaneous infections were recorded on seven plant species. Sonchus oleraceus and Eruca vesicaria are new hosts for S. minor; Cichorium intybus and Zinnia elegans are new hosts for Argentina. This fungus causes important damage on Helianthus annuus and Lactuca sativa, and it occasionally affects C. intybus and Solanum lycopersicum. Comparative in vitro and in planta studies were carried out with S. minor and S. sclerotiorum isolates obtained from sunflower.
