In vitro studies were carried out to identify causal fungi of Sclerotinia diseases in Cerrado region in Brazil. Temperature responses of mycelial growth of Sclerotinia sp. collected in Cerrado on P D A were similar to Japanese isolate of S. sclerotiorum S B-1 but not to that of S. trifoliorum Y W-4. In dual culture the mycelia of isolates in Cerrado and S. sclerotiorum S B-1 intermingled freely without the formation of a brown zone in the regions association on P D A medium, being in good agreement with Wong and Willets` reaction type (i). On the other hand, a white zone could be seen between mycelia of isolates in Cerrado and S. trifoliorum Y W-4. As a result, all the isolates of Sclerotinia sp. collected in Cerrado region should be identified as Sclerotinia sclerotiorum. |
