Abstract
The fungus Alternaria padwickii (Ganguly) M. B. Ellis is one of the most important pathogens of rice seed in Corrientes, Argentina. Currently information on the biology of fungus and in particular with regard to their behavior in culture media is limited therefore the aim of this study was to evaluate in vitro growth of the pathogen in different media, for which the mycelial growth was measured at three, six, nine and twelve days from sowing. The growth rate of the pathogen was quantified. Among the studied media, bean agar (1,46 mm • hr1), rice agar (1,52 mm • hr1) and malt extract agar (1,52 mm • hr-1) showed the best results. Bean agar (AP) was the only medium that favoured the sporulation of A. padwickii.
