Anthracnose caused by Colletotrichum lindemuthianum is one of the most important diseases in common beans (Phaseolus vulgaris L.). This research aimed at studying the Colletotrichum lindemuthianum in Paraná state region, Brazil, using race identification through differential cultivars. Nine races were identified from the eighteen isolates assessed: 7, 31, 65, 69, 73, 81, 87, 89 , Co-5 and Co-7 genes, were resistant to the identified races. These results showed the pathogenic variability and the importance of monitoring Colletotrichum lindemuthianum and resistant bean plant cultivars.

In 2003 and 2004, 32 isolates of Colletotrichum lindemuthianum obtained from the infected plants of field-grown common bean (Phaseolus vulgaris L.) in Santa Catarina state, Brazil were analyzed based on the virulence to 12 differential cultivars of Phaseolus vulgaris L.. Thirteen distinct races were identified, six of which had not been reported previously in Santa Catarina. This is the first report of the occurrence of 67, 83,101,103,105, and 581 races of C. lindemuthianum. Race 65 was most common (34%). All the isolates were compatible to the cultivars Michelite and Mexico 222. Some isolates infected not only differential cultivar of Mesoamerican origin, but also the ones of Andean origin.
Em 2003 e 2004, isolados de Colletotrichum lindemuthianum obtidas de plantas infectadas de feijoeiro comum (Phaseolus vulgaris L.) no Estado de Santa Catarina, Brasil foram analisadas baseando-se na virulência em 12 cultivares diferenciadoras de Phaseolus vulgaris L.. Treze raças distintas foram identificadas, sendo que seis delas não haviam sido reportadas anteriormente em Santa Catarina. Este é o primeiro registro de ocorrência das raças 67, 83, 101,103,105, e 581 do C. lindemuthianum. A raça mais comum foi a 65 (34%). Todos os isolados foram compatíveis com as cultivares Michelite e México 222. Alguns dos isolados infectaram tanto cultivares diferenciadoras de origem Mesoamericana como de origem Andina
