Regional surveys are being conducted at the CIDEFI to investigate the presence of wheat (Triticum aestivum L.) pathogens on leaves and seeds across the Argentinian cropping area. During the past 5 years in the wheat cropping area of Buenos Aires Province, Entre Ríos and Santa Fe Provinces, Argentina, several unusual diseases have been found on wheat leaves. From the symptomatic tissues, the fungi were isolated and identifi ed. To test pathogenicity and fulfi l Koch´s postulates, inoculationsof different wheat cultivars under greenhouse conditions were carried out; disease symptoms and the causal agents are described.
