Angular leaf spot (ALS), caused by Phaeoisariopsis griseola (Sacc.) Ferraris, is one of the most destructive and widespread problems of common bean (Phaseolus vulgaris L.) in Tucumán and other northwestern provinces of Argentina. Symptoms similar to those of ALS were observed during April 2005 on most plants of runner bean (P. coccineus L.) in an 80-ha field in Tafí del Valle, Tucumán (2,000 m above sea level). To our knowledge, this is the first report of ALS occurring on P. coccineus in Argentina. This report may prompt the inclusion of regular testing of seeds for ALS in P. coccineusproduction areas. A voucher culture has been deposited in the LPSC (Culture collection of the La Plata Spegazzini Institute) No. 844.
