First report of Phakopsora pachyrhizi on soybean in Costa Rica
Plant Disease 99 (3), 418-418
Abstract: Phakopsora meibomiae has been reported as Phakopsora pachyrhizi in Costa Rica but the latter species has not been confirmed in that country. During 2012 and 2013, soybean plants (Glycine max) grown in Costa Rica were observed with symptoms of yellow leaf spots, causing substantial defoliation. The fungus Phakopsora pachyrhizi was isolated from the diseased plants. The identification was based on DNA sequence analysis.
